    • This is different from your web login password

  5. Configure environment variables:

    INBOX_LV_EMAIL=your-username@inbox.lv
INBOX_LV_PASSWORD=your-special-imap-password

  6. Test the setup:

    cargo run --example test_auto_otp

For detailed setup instructions, see: examples/setup/auto_otp_setup.md

Manual .env Configuration

File Creation

# Create .env file in project root
touch .env

# Set restrictive permissions (recommended)
chmod 600 .env  # Unix/Linux/macOS only

Variable Format

Use proper formatting to handle special characters:

# Simple values (no spaces or special characters)
AXIOM_EMAIL=user@example.com

# Values with special characters (use quotes)
AXIOM_PASSWORD="my-complex-password!@#$"

# Values with spaces (use quotes)
SOME_VALUE="value with spaces"

# Avoid these characters without quotes: $ ` " ' \ # space

Special Character Handling

The library's EnvLoader properly handles special characters:

#![allow(unused)]
fn main() {
// Values are automatically parsed correctly
let password = env::var("AXIOM_PASSWORD")?; // Works with special chars
}

Characters requiring quotes:

  • Spaces: "password with spaces"
  • Dollar signs: "password$with$dollars"
  • Quotes: "password\"with\"quotes"
  • Backslashes: "password\\with\\backslashes"

Security Best Practices

Credential Management

  1. Use strong passwords:

    • 12+ characters with mixed case, numbers, symbols
    • Unique passwords for each service
    • Consider using a password manager

  2. Protect credential files:

    # Set restrictive permissions
chmod 600 .env

# Verify permissions
ls -la .env  # Should show: -rw-------

  3. Never commit credentials:

    # Ensure .env is in .gitignore
echo ".env" >> .gitignore

Network Security

  1. Use secure connections - axiomtrade-rs uses HTTPS/WSS by default
  2. Verify certificates - Built-in certificate validation
  3. Monitor authentication - Log successful/failed attempts
  4. Rotate credentials regularly - Update passwords periodically

Production Environment

  1. Environment isolation:

    # Different .env files for different environments
.env.development
.env.staging  
.env.production

  2. Secret management:

    • Consider using secret management services
    • Use environment variables in production
    • Avoid storing secrets in container images

  3. Access control:

    • Limit access to credential files
    • Use service accounts where appropriate
    • Implement proper logging and monitoring

Configuration Validation

Built-in Validation

Test your configuration using the provided tools:

# Comprehensive testing
cargo run --example environment_setup
# Choose: Test current configuration

# OTP-specific testing
cargo run --example test_auto_otp

# Basic authentication testing
cargo run --example basic_login

Manual Validation

Verify variables are loaded correctly:

#![allow(unused)]
fn main() {
use std::env;

fn validate_config() -> Result<(), Box<dyn std::error::Error>> {
    // Load environment variables
    dotenvy::dotenv().ok();
    
    // Check required variables
    let email = env::var("AXIOM_EMAIL")?;
    let password = env::var("AXIOM_PASSWORD")?;
    
    println!("Email configured: {}", email);
    println!("Password configured: [{}]", "*".repeat(password.len()));
    
    // Check optional OTP variables
    if let (Ok(otp_email), Ok(_otp_pass)) = (
        env::var("INBOX_LV_EMAIL"),
        env::var("INBOX_LV_PASSWORD")
    ) {
        println!("OTP automation configured for: {}", otp_email);
    } else {
        println!("Manual OTP entry will be required");
    }
    
    Ok(())
}
}

Environment Variable Priority

The library loads variables in this order (last wins):

  1. Process environment variables
  2. .env file in current directory
  3. .env file in parent directories (recursive search)

Override specific variables for testing:

# Override for single command
AXIOM_EMAIL=test@example.com cargo run --example basic_login

# Export for session
export RUST_LOG=debug
cargo run --example environment_setup

AXIOM_PASSWORD="password-with-special-chars!@#$"

Debug Steps

  1. Check environment loading:

    #![allow(unused)]
fn main() {
use std::env;
dotenvy::dotenv().ok();
for (key, value) in env::vars() {
    if key.starts_with("AXIOM_") || key.starts_with("INBOX_") {
        println!("{}: {}", key, if key.contains("PASSWORD") { "[HIDDEN]" } else { &value });
    }
}
}

  2. Test individual components:

    # Test just environment loading
cargo test env_loader

# Test just IMAP (if configured)
cargo run --example test_auto_otp

# Test just authentication
cargo run --example basic_login

  3. Enable verbose logging:

    export RUST_LOG=axiomtrade_rs=debug
cargo run --example your_example

Next Steps

After completing environment setup:

  1. Test authentication:

    cargo run --example basic_login

  2. Explore examples:

    ls examples/
cargo run --example portfolio_monitoring

  3. Build your application:

    use axiomtrade_rs::AxiomClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Environment is automatically loaded
    let client = AxiomClient::new().await?;
    // Your application logic here
    Ok(())
}

  4. Review additional documentation:

Automatic OTP

The Axiom Trade Rust client provides automatic OTP (One-Time Password) retrieval functionality that eliminates the need to manually check emails for verification codes. This feature uses IMAP protocol to fetch OTP codes directly from your inbox.lv email account.

Overview

When enabled, the automatic OTP system:

  • Monitors your inbox.lv email account for new Axiom security codes
  • Extracts 6-digit OTP codes from email subjects and bodies
  • Provides methods for immediate retrieval or waiting for new codes
  • Automatically marks processed emails as read to avoid duplicates

Prerequisites

  • Axiom Trade account with OTP authentication enabled
  • inbox.lv email account with IMAP access
  • Environment variables configured for email credentials

Configuration Setup

1. inbox.lv Account Setup

Create a dedicated inbox.lv email account for OTP purposes:

  1. Register Account

    • Navigate to https://www.inbox.lv/
    • Click "Register" and complete the form
    • Choose a unique username (becomes username@inbox.lv)
    • Verify your account through the confirmation email

  2. Enable IMAP Access

  3. Retrieve IMAP Credentials

    • After the 15-minute wait, refresh your settings page
    • Locate the "IMAP/SMTP Password" section
    • Copy the special IMAP password (different from web login password)
    • Save these credentials securely

2. IMAP Configuration

The client uses these IMAP settings for inbox.lv:

  • Server: mail.inbox.lv
  • Port: 993 (SSL/TLS)
  • Security: TLS encryption
  • Authentication: Username/password

3. Email Forwarding Setup

Configure Axiom Trade to send OTP emails to your inbox.lv account:

  1. Access Axiom Settings

    • Log into your Axiom Trade account
    • Navigate to Account Settings or Security Settings
    • Find "Email Preferences" or "Notification Settings"

  2. Configure Forwarding

    • Add your inbox.lv email as the notification address
    • Enable "Security Code" or "OTP" notifications
    • Save the configuration

  3. Test Email Delivery

    • Trigger an OTP request from Axiom Trade
    • Verify the email arrives at your inbox.lv account
    • Confirm subject format: "Your Axiom security code is XXXXXX"

4. Environment Variables

Set the required environment variables in your .env file:

# inbox.lv IMAP Configuration
INBOX_LV_EMAIL=your_username@inbox.lv
INBOX_LV_PASSWORD=your_special_imap_password

# Axiom Trade Credentials (if using automatic login)
AXIOM_EMAIL=your_axiom_email@domain.com
AXIOM_PASSWORD=your_axiom_password

Important Notes:

  • Use the IMAP password, not your web login password
  • Ensure no spaces around the = signs
  • Never commit .env files to version control

Usage Examples

Basic OTP Retrieval

#![allow(unused)]
fn main() {
use axiomtrade_rs::email::otp_fetcher::{OtpFetcher, from_env};

if let Some(otp) = fetcher.fetchotp()? {
    println!("Retrieved OTP: {}", otp);
} else {
    println!("No unread OTP emails found");
}
}

Waiting for New OTP

#![allow(unused)]
fn main() {
// Wait up to 60 seconds for a new OTP email, checking every 5 seconds
let timeout_seconds = 60;

fn main() {
// Fetch OTP from emails received in the last 3 minutes
let minutes_ago = 3;

if let Some(otp) = fetcher.fetchotp_recent(minutes_ago)? {
    println!("Recent OTP found: {}", otp);
} else {
    println!("No OTP emails from the last {} minutes", minutes_ago);
}
}

Integration with Client Authentication

#![allow(unused)]
fn main() {
use axiomtrade_rs::AxiomClient;

let mut client = AxiomClient::new().await?;

// Attempt login
let login_result = client.login(&email, &password).await?;

if login_result.requires_otp {
    // Use automatic OTP retrieval
    if let Some(fetcher) = from_env()? {
        if let Some(otp) = fetcher.wait_for_otp(60, 5)? {
            client.verify_otp(&otp).await?;
            println!("Authentication successful with automatic OTP");
        } else {
            return Err("Failed to retrieve OTP automatically".into());
        }
    } else {
        // Fall back to manual OTP entry
        print!("Enter OTP: ");
        // ... manual input logic
    }
}
}

OTP Extraction Methods

The system uses multiple strategies to extract OTP codes from emails:

Subject Line Extraction

  • Primary pattern: "Your Axiom security code is (\d{6})"
  • Extracts 6-digit codes from email subjects

Body Content Extraction

The system tries multiple patterns in order:

  1. "Your Axiom security code is[:\s]+(\d{6})"
  2. "Your security code is[:\s]+(\d{6})"
  3. "security code[:\s]+(\d{6})"
  4. HTML tags: <span>, <b>, <strong> containing 6 digits
  5. Fallback: Any 6-digit number in context containing "security code" or "Your Axiom"

Example Email Formats

Subject Line Format:

Subject: Your Axiom security code is 123456

Plain Text Body:

Your Axiom security code is: 123456

This code will expire in 10 minutes.

HTML Body:

<div style="background-color: #f5f5f5; padding: 15px;">
  <span style="font-size: 24px; font-weight: bold;">123456</span>
</div>
<p>Your Axiom security code</p>

Troubleshooting OTP Issues

Connection Problems

Issue: "IMAP connection failed"

  • Cause: IMAP not enabled or incorrect credentials
  • Solutions:
    • Verify 15-minute IMAP activation wait period completed
    • Check IMAP password vs web login password
    • Confirm email address spelling in environment variables
    • Test connection manually using an IMAP client

Issue: "Authentication failed to inbox.lv"

  • Cause: Wrong IMAP credentials
  • Solutions:
    • Verify IMAP password from inbox.lv settings
    • Check for typos in email address
    • Try logging into inbox.lv webmail to verify credentials
    • Regenerate IMAP password if necessary

Email Delivery Problems

Issue: "No OTP emails found"

  • Cause: Email forwarding not configured or emails not arriving
  • Solutions:
    • Verify Axiom Trade sends OTP emails to inbox.lv address
    • Check spam/junk folder in inbox.lv
    • Manually trigger OTP and verify email arrives
    • Confirm email subject format matches expected pattern

Issue: "OTP extraction failed"

  • Cause: Email format changed or parsing issue
  • Solutions:
    • Check recent OTP email for exact subject format
    • Verify subject contains "Your Axiom security code is"
    • Review email body format if subject extraction fails
    • Report format changes to maintain compatibility

Debug and Testing

Enable debug logging for detailed information:

RUST_LOG=debug

Test individual components:

#![allow(unused)]
fn main() {
// Test IMAP connection
let fetcher = OtpFetcher::new(
    "your_email@inbox.lv".to_string(),
    "your_imap_password".to_string()
);

// Test email parsing
let email_body = "Your Axiom security code is: 123456";
let result = fetcher.extract_otp_from_email(email_body)?;
}

Manual verification steps:

  1. Send test email to inbox.lv account
  2. Verify email appears in webmail interface
  3. Request OTP manually from Axiom Trade
  4. Check exact subject line format in received email

Security Considerations

Email Account Security

  • Use dedicated inbox.lv account only for OTP purposes
  • Avoid using this email for other services
  • Consider the email account semi-public
  • Use strong, unique password for inbox.lv account

Credential Management

  • Store IMAP credentials securely in environment variables
  • Never commit .env files to version control
  • Use proper file permissions on configuration files
  • Consider using OS keychain for production deployments

Access Control

  • The inbox.lv account only needs to receive emails
  • Enable two-factor authentication on Axiom Trade account
  • Regularly review account access and settings
  • Monitor for unauthorized access attempts

Network Security

  • All IMAP connections use TLS encryption
  • Verify SSL certificate validation
  • Use secure networks for production systems
  • Consider VPN for additional protection

Alternative Configurations

Other Email Providers

The OTP fetcher can be adapted for other IMAP-enabled providers:

Gmail (requires app-specific passwords):

#![allow(unused)]
fn main() {
let fetcher = OtpFetcher::new(
    "user@gmail.com".to_string(),
    "app_specific_password".to_string()
);
// Note: Different IMAP server settings required
}

Custom Email Servers:

  • Modify IMAP_DOMAIN and IMAP_PORT constants
  • Adjust TLS settings as needed
  • Update authentication method if required

Manual Fallback

Always provide manual OTP entry as fallback:

#![allow(unused)]
fn main() {
fn get_otp_manual() -> Result<String> {
    print!("Enter OTP code: ");
    io::stdout().flush()?;
    
    let mut input = String::new();
    io::stdin().read_line(&mut input)?;
    
    Ok(input.trim().to_string())
}

// Use in authentication flow
let otp = if let Some(fetcher) = from_env()? {
    fetcher.fetchotp()?.unwrap_or_else(|| get_otp_manual())
} else {
    get_otp_manual()?
};
}

Performance and Limitations

Performance Characteristics

  • IMAP connection establishment: ~1-2 seconds
  • Email search and retrieval: <1 second
  • OTP extraction: <100 milliseconds
  • Total process time: 2-4 seconds typically

Rate Limiting

  • IMAP servers may limit connection frequency
  • Implement backoff strategies for production use
  • Consider connection pooling for high-frequency operations

Email Limitations

  • Only processes UNREAD emails to avoid duplicates
  • Requires emails to match specific subject patterns
  • Dependent on email delivery timing and reliability
  • Limited to 6-digit numeric OTP codes

Best Practices

  • Use timeouts to prevent hanging operations
  • Implement retry logic with exponential backoff
  • Log operations for debugging and monitoring
  • Handle network interruptions gracefully
  • Cache credentials securely to avoid repeated lookups

Login and Sessions

This guide covers the complete authentication and session management system in axiomtrade-rs, including basic login, OTP verification, cookie-based authentication, and comprehensive error handling.

Overview

The authentication system in axiomtrade-rs provides a robust, secure login mechanism with automatic OTP fetching, cookie-based session persistence, and comprehensive token management. The system is designed to handle the two-step authentication process required by Axiom Trade's API.

Basic Login Flow

The standard login process involves two steps:

  1. Password Verification: Submit email and hashed password to get an OTP JWT token
  2. OTP Verification: Submit the OTP code to complete authentication and receive access tokens

Simple Login Example

use axiomtrade_rs::auth::AuthClient;
use std::env;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load environment variables
    dotenvy::dotenv().ok();
    
    let email = env::var("AXIOM_EMAIL")?;
    let password = env::var("AXIOM_PASSWORD")?;

    // Create auth client
    let mut auth_client = AuthClient::new()?;
    
    // Perform login (automatic OTP if configured)
    let tokens = auth_client.login(&email, &password, None).await?;
    
    println!("Login successful!");
    println!("Access token: {}...", &tokens.access_token[..20]);
    
    Ok(())
}

Manual OTP Entry

If automatic OTP fetching is not configured, you can provide the OTP manually:

use std::io::{self, Write};

fn get_otp_from_user() -> Result<String, io::Error> {
    print!("Enter OTP code: ");
    io::stdout().flush()?;
    
    let mut otp = String::new();
    io::stdin().read_line(&mut otp)?;
    
    Ok(otp.trim().to_string())
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut auth_client = AuthClient::new()?;
    
    // Get OTP from user if auto-fetch not configured
    let otp_code = if env::var("INBOX_LV_EMAIL").is_ok() {
        None  // Auto-fetch enabled
    } else {
        Some(get_otp_from_user()?)
    };
    
    let tokens = auth_client.login(&email, &password, otp_code).await?;
    
    Ok(())
}

Login with OTP

The system supports automatic OTP fetching from inbox.lv email accounts when properly configured.

Automatic OTP Configuration

Set up environment variables for automatic OTP fetching:

# Axiom Trade credentials
AXIOM_EMAIL=your.email@example.com
AXIOM_PASSWORD=your_password

# Inbox.lv credentials for OTP auto-fetching
INBOX_LV_EMAIL=your_username@inbox.lv
INBOX_LV_PASSWORD=your_imap_password

OTP Verification Example

use axiomtrade_rs::auth::AuthClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut auth_client = AuthClient::new()?;
    
    // Check if auto-OTP is configured
    let auto_otp_configured = env::var("INBOX_LV_EMAIL").is_ok() 
        && env::var("INBOX_LV_PASSWORD").is_ok();
    
    if auto_otp_configured {
        println!("Automatic OTP retrieval is configured");
        println!("The system will automatically fetch OTP from inbox.lv");
    } else {
        println!("Manual OTP entry will be required");
    }
    
    // Login with automatic OTP handling
    let tokens = auth_client.login(&email, &password, None).await?;
    
    println!("Login successful with OTP verification!");
    
    Ok(())
}

Full Login Result

Use login_full() to get complete authentication information including Turnkey credentials:

#![allow(unused)]
fn main() {
let login_result = auth_client.login_full(&email, &password, None).await?;

// Access tokens
let tokens = login_result.tokens;

// Turnkey credentials for wallet operations
if let Some(turnkey) = login_result.turnkey_credentials {
    println!("Turnkey Organization ID: {}", turnkey.organization_id);
    println!("Turnkey User ID: {}", turnkey.user_id);
    println!("Client Secret: {}...", &turnkey.client_secret[..8]);
}

// User information
if let Some(user) = login_result.user_info {
    println!("User ID: {:?}", user.id);
    println!("Email: {:?}", user.email);
}
}

The authentication system automatically manages HTTP cookies for session persistence, which is particularly useful for web-based integrations.

use axiomtrade_rs::auth::{AuthClient, AuthCookies};
use std::collections::HashMap;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut auth_client = AuthClient::new()?;
    
    // Login and get tokens
    let tokens = auth_client.login(&email, &password, None).await?;
    
    // Cookies are automatically managed by the HTTP client
    // The auth client maintains cookie store with:
    // - auth-access-token (HttpOnly)
    // - auth-refresh-token (HttpOnly) 
    // - g_state (Google OAuth state)
    // - Additional session cookies
    
    println!("Authentication cookies are automatically managed");
    
    Ok(())
}

The authentication system implements several security best practices for cookies:

  • HttpOnly Flag: Prevents JavaScript access to authentication cookies
  • Secure Flag: Ensures cookies are only transmitted over HTTPS
  • SameSite Protection: Provides CSRF protection
  • Path Restrictions: Limits cookie scope to appropriate paths
  • Automatic Expiry: Manages cookie lifecycle and cleanup

Making Authenticated Requests

The AuthClient provides methods for making authenticated API requests with automatic cookie handling:

#![allow(unused)]
fn main() {
use reqwest::Method;
use serde_json::json;

// Make authenticated request with automatic cookie handling
let response = auth_client.make_authenticated_request(
    Method::GET,
    "https://api.axiom.trade/portfolio/balance",
    None
).await?;

// Make authenticated POST request with JSON body
let body = json!({
    "token_address": "So11111111111111111111111111111111111111112",
    "amount": "1000000"
});

let response = auth_client.make_authenticated_request(
    Method::POST,
    "https://api.axiom.trade/trade/buy",
    Some(body)
).await?;
}

Session Management

The system provides comprehensive session management with automatic token refresh and persistence.

Token Persistence

use axiomtrade_rs::auth::{TokenManager, AuthClient};
use std::path::PathBuf;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create token manager with persistent storage
    let tokens_file = PathBuf::from(".axiom_tokens.json");
    let token_manager = TokenManager::new(Some(tokens_file));
    
    // Check for existing session
    if let Some(existing_tokens) = token_manager.get_tokens().await {
        println!("Found existing session");
        
        if !existing_tokens.is_expired() {
            println!("Session is still valid");
            // Use existing tokens
        } else {
            println!("Session expired, need to refresh");
            // Refresh or re-login
        }
    } else {
        println!("No existing session, performing new login");
        
        let mut auth_client = AuthClient::new()?;
        let tokens = auth_client.login(&email, &password, None).await?;
        
        // Save tokens for future use
        token_manager.set_tokens(tokens).await?;
    }
    
    Ok(())
}

Automatic Token Refresh

The authentication client automatically handles token refresh when making API requests:

#![allow(unused)]
fn main() {
// Tokens are automatically refreshed when needed
let mut auth_client = AuthClient::new()?;

// This will automatically refresh tokens if they're expired
let valid_tokens = auth_client.ensure_valid_authentication().await?;

println!("Guaranteed valid tokens: {}...", &valid_tokens.access_token[..20]);
}

Multiple Session Management

#![allow(unused)]
fn main() {
use axiomtrade_rs::auth::SessionManager;

// Manage multiple sessions for different accounts
let session_manager = SessionManager::new(
    Some(PathBuf::from(".axiom_sessions.json")), 
    true  // Enable encryption
);

// Example session files for different purposes
let session_files = vec![
    ".axiom_session_trading.json",
    ".axiom_session_portfolio.json",
    ".axiom_session_notifications.json",
];

for session_file in session_files {
    let path = PathBuf::from(session_file);
    if path.exists() {
        println!("Found session: {}", session_file);
    }
}
}

Error Handling

The authentication system provides comprehensive error handling for various failure scenarios.

Authentication Error Types

#![allow(unused)]
fn main() {
use axiomtrade_rs::auth::error::AuthError;

match auth_client.login(&email, &password, None).await {
    Ok(tokens) => {

    }
    Err(AuthError::InvalidCredentials) => {
        println!("Invalid email or password");
    }
    Err(AuthError::InvalidOtp) => {
        println!("Invalid OTP code");
    }
    Err(AuthError::OtpRequired) => {
        println!("OTP required but not provided");
    }
    Err(AuthError::TokenExpired) => {
        println!("Authentication token has expired");
    }
    Err(AuthError::TokenNotFound) => {
        println!("No authentication token found");
    }
    Err(AuthError::NetworkError(e)) => {
        println!("Network error: {}", e);
    }
    Err(AuthError::EmailError(msg)) => {
        println!("Email fetcher error: {}", msg);
    }
    Err(e) => {
        println!("Other authentication error: {}", e);
    }
}
}

        .map_err(|e| format!("Failed to create auth client: {}", e))?;
    
    let max_retries = 3;
    let mut attempts = 0;
    
    loop {
        attempts += 1;
        
        match auth_client.login(email, password, None).await {
            Ok(tokens) => {
                println!("Login successful on attempt {}", attempts);
                return Ok(());
            }
            Err(AuthError::NetworkError(e)) if attempts < max_retries => {
                println!("Network error on attempt {}, retrying: {}", attempts, e);
                tokio::time::sleep(tokio::time::Duration::from_secs(2)).await;
                continue;
            }
            Err(AuthError::InvalidCredentials) => {
                return Err("Invalid credentials - check email and password".into());
            }
            Err(AuthError::OtpRequired) => {
                return Err("OTP required but auto-fetching not configured".into());
            }
            Err(AuthError::EmailError(msg)) => {
                return Err(format!("Email OTP fetching failed: {}", msg).into());
            }
            Err(e) => {
                return Err(format!("Login failed: {}", e).into());
            }
        }
    }
}
}

Recovery Strategies

#![allow(unused)]
fn main() {
async fn handle_authentication_failure(
    auth_client: &mut AuthClient,
    error: AuthError
) -> Result<(), AuthError> {
    match error {

            // Try to refresh tokens
            match auth_client.refresh_tokens().await {
                Ok(_) => {
                    println!("Tokens refreshed successfully");
                    Ok(())
                }
                Err(_) => {
                    println!("Token refresh failed, need to re-login");
                    Err(AuthError::NotAuthenticated)
                }
            }
        }
        AuthError::NetworkError(_) => {
            // Implement exponential backoff
            tokio::time::sleep(tokio::time::Duration::from_secs(5)).await;
            Err(error)
        }
        AuthError::OtpRequired => {
            println!("Configure automatic OTP fetching:");
            println!("1. Create inbox.lv account");
            println!("2. Set INBOX_LV_EMAIL and INBOX_LV_PASSWORD");
            println!("3. Forward Axiom OTP emails to inbox.lv");
            Err(error)
        }
        _ => Err(error)
    }
}
}

Complete Example: Production Login

Here's a complete example demonstrating production-ready authentication with all features:

use axiomtrade_rs::auth::{AuthClient, TokenManager, AuthError};
use axiomtrade_rs::client::EnhancedClient;
use std::env;
use std::path::PathBuf;

#[tokio::main]

            println!("Warning: Portfolio access failed: {}", e);
        }
    }
    
    Ok(())
}

The Axiom Trade Rust client provides a comprehensive token management system that handles authentication tokens, automatic refresh, persistent storage, and validation. This system ensures secure and reliable API access while maintaining session integrity.

Overview

The token management system consists of two main components:

  • AuthTokens: Core JWT token structure containing access and refresh tokens
  • TokenManager: Thread-safe manager for storing, validating, and persisting tokens

Token Types

Access Tokens

Access tokens are JWT tokens used to authenticate API requests. They have a limited lifespan and are included in the Authorization header of HTTP requests.

#![allow(unused)]
fn main() {
// Access token is automatically included in API requests
let balance = client.get_portfolio().await?;
}

Refresh Tokens

Refresh tokens are long-lived tokens used to obtain new access tokens when they expire. They provide a secure way to maintain authentication without requiring the user to log in repeatedly.

#![allow(unused)]
fn main() {
// Refresh happens automatically when needed
let new_tokens = auth_client.refresh_tokens().await?;
}

Token Structure

The AuthTokens struct contains all necessary token information:

#![allow(unused)]
fn main() {
pub struct AuthTokens {
    pub access_token: String,      // JWT access token
    pub refresh_token: String,     // JWT refresh token  
    pub expires_at: Option<DateTime<Utc>>, // Token expiration time
}
}

TokenManager

The TokenManager provides thread-safe token operations with optional persistent storage.

Creating a TokenManager

#![allow(unused)]
fn main() {
use axiomtrade_rs::auth::TokenManager;
use std::path::PathBuf;

// In-memory token storage
let token_manager = TokenManager::new(None);

// Persistent token storage
let storage_path = PathBuf::from("tokens.json");
let token_manager = TokenManager::new(Some(storage_path));

// Create from environment variables
let token_manager = TokenManager::from_env()?;
}

Environment Variable Setup

The TokenManager can automatically load tokens from environment variables:

export AXIOM_ACCESS_TOKEN="your_access_token_here"
export AXIOM_REFRESH_TOKEN="your_refresh_token_here"

#![allow(unused)]
fn main() {
// Automatically loads tokens from environment
if let Some(manager) = TokenManager::from_env()? {
    println!("Tokens loaded from environment");
}
}

Token Operations

Setting Tokens

Store new authentication tokens in the manager:

#![allow(unused)]
fn main() {
use axiomtrade_rs::auth::types::AuthTokens;
use chrono::{Utc, Duration};

let tokens = AuthTokens {
    access_token: "eyJhbGciOiJIUzI1NiIs...".to_string(),
    refresh_token: "refresh_token_value".to_string(),
    expires_at: Some(Utc::now() + Duration::hours(1)),
};

token_manager.set_tokens(tokens).await?;
}

Retrieving Tokens

Get stored tokens for API requests:

#![allow(unused)]
fn main() {
// Get complete token structure
if let Some(tokens) = token_manager.get_tokens().await {
    println!("Access token: {}", tokens.access_token);
}

// Get individual tokens
let access_token = token_manager.get_access_token().await?;
let refresh_token = token_manager.get_refresh_token().await?;
}

Token Validation

Check token status before making API calls:

#![allow(unused)]
fn main() {
// Check if tokens are expired (with 5-minute buffer)
if token_manager.is_expired().await {
    println!("Tokens have expired");
}

// Check if tokens need refresh (with 15-minute buffer)
if token_manager.needs_refresh().await {
    println!("Tokens should be refreshed soon");
}
}

Clearing Tokens

Remove stored tokens and delete persistent storage:

#![allow(unused)]
fn main() {
// Clear tokens from memory and delete storage file
token_manager.clear().await?;
}

Token Storage and Persistence

File-Based Storage

When a storage path is provided, tokens are automatically saved to disk as JSON:

{
  "access_token": "eyJhbGciOiJIUzI1NiIs...",
  "refresh_token": "refresh_token_value",
  "expires_at": "2024-01-15T10:30:00Z"
}

Storage Benefits

  • Persistence: Tokens survive application restarts
  • Security: Only stored locally on the filesystem
  • Convenience: Automatic loading on TokenManager creation

Storage Location

Choose an appropriate storage location based on your application:

#![allow(unused)]
fn main() {
// User-specific storage
let storage_path = dirs::config_dir()
    .unwrap()
    .join("axiomtrade")
    .join("tokens.json");

// Application-specific storage  
let storage_path = PathBuf::from("./config/tokens.json");

// Temporary storage
let storage_path = std::env::temp_dir().join("axiom_tokens.json");
}

Automatic Token Refresh

The token management system provides intelligent refresh logic:

Refresh Timing

  • Expiration Buffer: Tokens are considered expired 5 minutes before actual expiration
  • Refresh Buffer: Tokens should be refreshed 15 minutes before expiration
  • Automatic Refresh: The client automatically refreshes tokens when needed

Refresh Implementation

#![allow(unused)]
fn main() {
// Manual refresh check and execution
if token_manager.needs_refresh().await {
    // Refresh logic would be implemented in the auth client
    let new_tokens = auth_client.refresh_tokens().await?;
    token_manager.set_tokens(new_tokens).await?;
}
}

Security Considerations

Token Protection

  • Local Storage Only: Tokens are never transmitted except for authentication
  • File Permissions: Ensure token files have appropriate read/write permissions
  • Environment Variables: Use secure environment variable management

Best Practices

  1. Regular Rotation: Implement token refresh before expiration
  2. Secure Storage: Use appropriate file permissions for token storage
  3. Error Handling: Always handle token-related errors gracefully
  4. Cleanup: Clear tokens on logout or application termination
#![allow(unused)]
fn main() {
// Secure token file permissions (Unix-like systems)
#[cfg(unix)]
fn set_token_file_permissions(path: &Path) -> Result<(), std::io::Error> {
    use std::fs;
    use std::os::unix::fs::PermissionsExt;
    
    let mut perms = fs::metadata(path)?.permissions();
    perms.set_mode(0o600); // Read/write for owner only
    fs::set_permissions(path, perms)?;
    Ok(())
}
}

Error Handling

The token management system uses structured error handling:

#![allow(unused)]
fn main() {
use axiomtrade_rs::auth::error::AuthError;

match token_manager.get_access_token().await {
    Ok(token) => {
        // Use token for API request
    }
    Err(AuthError::TokenNotFound) => {
        // Handle missing tokens - may need to log in
    }
    Err(AuthError::TokenExpired) => {
        // Handle expired tokens - refresh or re-authenticate
    }
    Err(e) => {
        // Handle other errors
        eprintln!("Token error: {}", e);
    }
}
}

Thread Safety

The TokenManager is designed for concurrent access:

#![allow(unused)]
fn main() {
use std::sync::Arc;

// Share TokenManager across threads
let manager = Arc::new(TokenManager::new(None));
let manager_clone = Arc::clone(&manager);

tokio::spawn(async move {
    // Safe concurrent access
    let tokens = manager_clone.get_tokens().await;
});
}

Integration Example

Complete example showing token management integration:

use axiomtrade_rs::auth::{TokenManager, AuthClient};
use std::path::PathBuf;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create token manager with persistent storage
    let storage_path = PathBuf::from("tokens.json");
    let token_manager = TokenManager::new(Some(storage_path));
    
    // Check if we have valid tokens
    if token_manager.is_expired().await {
        // Need to authenticate
        let auth_client = AuthClient::new();
        let login_result = auth_client.login("user@example.com", "password").await?;
        token_manager.set_tokens(login_result.tokens).await?;
    } else if token_manager.needs_refresh().await {
        // Refresh tokens proactively
        let auth_client = AuthClient::new();
        let new_tokens = auth_client.refresh_tokens().await?;
        token_manager.set_tokens(new_tokens).await?;
    }
    
    // Use tokens for API requests
    let access_token = token_manager.get_access_token().await?;
    println!("Ready to make authenticated requests");
    
    Ok(())
}

Advanced Usage

            return Err(AuthError::TokenExpired);
        }
        
        if self.token_manager.needs_refresh().await {
            // Proactive refresh
            let new_tokens = self.auth_client.refresh_tokens().await?;
            self.token_manager.set_tokens(new_tokens).await?;
        }
        
        Ok(())
    }
    
    pub async fn get_valid_access_token(&self) -> Result<String, AuthError> {
        self.ensure_valid_tokens().await?;
        self.token_manager.get_access_token().await
    }
}
}

        let backup_manager = TokenManager::new(Some(backup_path.to_path_buf()));
        backup_manager.set_tokens(tokens).await?;
    }
    Ok(())

}

The token management system provides a robust foundation for maintaining authenticated sessions with the Axiom Trade API while ensuring security, reliability, and ease of use.

Session Management

This document covers the comprehensive session management system in axiomtrade-rs, which handles authentication state, persistence, and multi-session support.

Overview

The SessionManager provides a centralized system for managing authentication sessions that include:

  • JWT tokens (access and refresh)
  • HTTP cookies for browser-like authentication
  • Turnkey wallet integration sessions
  • Session metadata and tracking
  • Persistent storage capabilities

Session Lifecycle

1. Session Creation

Sessions are created after successful authentication through multiple pathways:

#![allow(unused)]
fn main() {
use axiomtrade_rs::auth::{SessionManager, AuthTokens, UserInfo};
use std::path::PathBuf;

// Create session manager with persistent storage
let storage_path = Some(PathBuf::from(".axiom_session.json"));
let session_manager = SessionManager::new(storage_path, true);

// Method 1: Basic session creation
let tokens = AuthTokens {
    access_token: "jwt_access_token".to_string(),
    refresh_token: "jwt_refresh_token".to_string(),
    expires_at: Some(chrono::Utc::now() + chrono::Duration::hours(1)),
};

session_manager.create_session(tokens, user_info, cookies).await?;

// Method 2: Session from complete login result
let login_result = auth_client.login_with_otp(&credentials, &otp_code).await?;
session_manager.create_session_from_login_result(login_result, cookies).await?;
}

2. Session Validation

The session manager provides multiple validation levels:

#![allow(unused)]
fn main() {
// Check if session exists and is valid
if session_manager.is_session_valid().await {
    println!("Session is active and valid");
}

// Check if session needs token refresh
if session_manager.needs_refresh().await {
    println!("Session needs token refresh");
    // Trigger token refresh process
}

// Get detailed session summary
let summary = session_manager.get_session_summary().await;
println!("Session status: {}", summary);
}

3. Session Updates

Sessions are automatically updated during API operations:

#![allow(unused)]
fn main() {
// Update tokens after refresh
let new_tokens = auth_client.refresh_tokens().await?;
session_manager.update_tokens(new_tokens).await?;

// Update cookies from API responses
let new_cookies = AuthCookies::parse_from_headers(&response.headers());
session_manager.update_cookies(new_cookies).await?;

// Track API calls
session_manager.mark_api_call(Some("api.axiom.trade")).await;
}

4. Session Termination

Sessions can be cleared manually or automatically:

#![allow(unused)]
fn main() {
// Manual session cleanup
session_manager.clear_session().await;

// Automatic cleanup on token expiration
// Sessions become invalid when tokens expire beyond refresh window
}

Session Persistence

Automatic Persistence

When auto_save is enabled, sessions are automatically saved after modifications:

#![allow(unused)]
fn main() {
// Enable auto-save during manager creation
let session_manager = SessionManager::new(
    Some(PathBuf::from(".axiom_session.json")),
    true  // auto_save enabled
);

// All session updates are automatically persisted
session_manager.update_tokens(new_tokens).await?;  // Auto-saved
session_manager.update_cookies(new_cookies).await?;  // Auto-saved
}

Manual Persistence

For fine-grained control over when sessions are saved:

#![allow(unused)]
fn main() {
// Disable auto-save for manual control
let session_manager = SessionManager::new(storage_path, false);

// Make multiple changes
session_manager.update_tokens(new_tokens).await?;
session_manager.update_cookies(new_cookies).await?;

// Save manually when ready
session_manager.save_session().await?;
}

Session Loading

Sessions are automatically loaded from storage on manager creation:

#![allow(unused)]
fn main() {
// Sessions are loaded automatically if storage file exists
let session_manager = SessionManager::new(
    Some(PathBuf::from(".axiom_session.json")),
    true
);

// Manual loading (if needed)
session_manager.load_session().await?;
}

Multi-Session Support

Session Isolation

Each SessionManager instance manages one authentication session:

#![allow(unused)]
fn main() {
// Multiple isolated sessions
let trading_session = SessionManager::new(
    Some(PathBuf::from(".axiom_trading_session.json")),
    true
);

let monitoring_session = SessionManager::new(
    Some(PathBuf::from(".axiom_monitoring_session.json")),
    true
);

// Each session maintains independent state
trading_session.create_session(trading_tokens, None, None).await?;
monitoring_session.create_session(monitoring_tokens, None, None).await?;
}

Session Switching

For applications needing multiple concurrent sessions:

#![allow(unused)]
fn main() {
use std::collections::HashMap;

struct MultiSessionManager {
    sessions: HashMap<String, SessionManager>,
    active_session: Option<String>,
}

impl MultiSessionManager {
    pub async fn switch_session(&mut self, session_id: &str) -> Result<(), AuthError> {
        if self.sessions.contains_key(session_id) {
            self.active_session = Some(session_id.to_string());
            Ok(())
        } else {
            Err(AuthError::NotAuthenticated)
        }
    }
    
    pub async fn get_active_session(&self) -> Option<&SessionManager> {
        self.active_session
            .as_ref()
            .and_then(|id| self.sessions.get(id))
    }
}
}

Session Validation

Token Validation

The session manager implements intelligent token validation:

#![allow(unused)]
fn main() {
impl AuthTokens {
    // Checks if token is expired with 5-minute buffer
    pub fn is_expired(&self) -> bool {
        match self.expires_at {
            Some(expires_at) => {
                let buffer = chrono::Duration::minutes(5);
                chrono::Utc::now() >= (expires_at - buffer)
            }
            None => false,
        }
    }
    
    // Checks if token needs refresh with 15-minute buffer
    pub fn needs_refresh(&self) -> bool {
        match self.expires_at {
            Some(expires_at) => {
                let buffer = chrono::Duration::minutes(15);
                chrono::Utc::now() >= (expires_at - buffer)
            }
            None => false,
        }
    }
}
}

HTTP cookies are validated for completeness:

#![allow(unused)]
fn main() {
impl AuthSession {
    pub fn has_valid_cookies(&self) -> bool {
        self.cookies.auth_access_token.is_some() 
            && self.cookies.auth_refresh_token.is_some()
    }
}
}

Turnkey Session Validation

Turnkey integration sessions have separate validation:

#![allow(unused)]
fn main() {
impl AuthSession {
    pub fn turnkey_needs_refresh(&self) -> bool {
        if let Some(turnkey) = &self.turnkey_session {
            if let Some(expires_at) = turnkey.expires_at {
                let buffer = chrono::Duration::hours(1);
                chrono::Utc::now() >= (expires_at - buffer)
            } else {
                false
            }
        } else {
            false
        }
    }
}
}

Logout and Cleanup

Immediate Cleanup

Clear session data immediately:

#![allow(unused)]
fn main() {
// Clear session from memory and optionally delete storage file
session_manager.clear_session().await;

// Session is now invalid
assert!(!session_manager.is_session_valid().await);
}

Secure Cleanup

For security-sensitive applications:

#![allow(unused)]
fn main() {
// 1. Revoke tokens on server (if supported)
if let Some(refresh_token) = session_manager.get_refresh_token().await {
    auth_client.revoke_token(&refresh_token).await?;
}

// 2. Clear local session
session_manager.clear_session().await;

// 3. Clear any cached credentials
// (Application-specific cleanup)
}

Automatic Cleanup

Sessions automatically become invalid when tokens expire:

#![allow(unused)]
fn main() {
// Sessions with expired tokens return false
let is_valid = session_manager.is_session_valid().await;

// Cleanup expired sessions periodically
async fn cleanup_expired_sessions(managers: &[SessionManager]) {
    for manager in managers {
        if !manager.is_session_valid().await {
            manager.clear_session().await;
        }
    }
}
}

Session Metadata

Tracking Information

Sessions include comprehensive metadata:

#![allow(unused)]
fn main() {
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct SessionMetadata {
    pub created_at: chrono::DateTime<chrono::Utc>,
    pub last_refreshed_at: Option<chrono::DateTime<chrono::Utc>>,
    pub last_api_call_at: Option<chrono::DateTime<chrono::Utc>>,
    pub current_api_server: Option<String>,
    pub user_agent: String,
    pub ip_address: Option<String>,
    pub client_fingerprint: Option<String>,
}

// Usage examples
let session = session_manager.get_session().await.unwrap();
let age_minutes = session.session_metadata.session_age_minutes();
let last_api_call = session.session_metadata.minutes_since_last_api_call();
}

Usage Analytics

Track session usage patterns:

#![allow(unused)]
fn main() {
// Mark API calls for analytics
session_manager.mark_api_call(Some("api.axiom.trade")).await;

// Get session summary with timing information
let summary = session_manager.get_session_summary().await;
// Output: "Session: VALID | Tokens: VALID | Cookies: PRESENT | Turnkey: ACTIVE | Age: 45m | Last API: 2m ago"
}

Integration Examples

HTTP Client Integration

Use sessions with HTTP requests:

#![allow(unused)]
fn main() {
use reqwest::Client;

async fn make_authenticated_request(
    session_manager: &SessionManager,
    client: &Client,
    url: &str,
) -> Result<reqwest::Response, Box<dyn std::error::Error>> {
    let mut request = client.get(url);
    
    // Add authorization header
    if let Some(token) = session_manager.get_access_token().await {
        request = request.header("Authorization", format!("Bearer {}", token));
    }
    
    // Add cookie header
    if let Some(cookies) = session_manager.get_cookie_header().await {
        request = request.header("Cookie", cookies);
    }
    
    // Add user agent from session
    if let Some(session) = session_manager.get_session().await {
        request = request.header("User-Agent", session.get_user_agent());
    }
    
    let response = request.send().await?;
    
    // Track API call
    session_manager.mark_api_call(Some("api.axiom.trade")).await;
    
    Ok(response)
}
}

WebSocket Integration

Use sessions for WebSocket authentication:

#![allow(unused)]
fn main() {
use tokio_tungstenite::{connect_async, tungstenite::Message};

async fn connect_websocket(
    session_manager: &SessionManager,
) -> Result<(), Box<dyn std::error::Error>> {
    if !session_manager.is_session_valid().await {
        return Err("Invalid session for WebSocket connection".into());
    }
    
    let access_token = session_manager.get_access_token().await
        .ok_or("No access token available")?;
    
    let ws_url = format!("wss://ws.axiom.trade?token={}", access_token);
    let (ws_stream, _) = connect_async(&ws_url).await?;
    
    // WebSocket connection established with session authentication
    Ok(())
}
}

Error Handling

Handle session-related errors gracefully:

#![allow(unused)]
fn main() {
use axiomtrade_rs::auth::error::AuthError;

async fn handle_session_error(
    result: Result<(), AuthError>,
    session_manager: &SessionManager,
) -> Result<(), AuthError> {
    match result {
        Err(AuthError::NotAuthenticated) => {
            // Session invalid, clear and require re-authentication
            session_manager.clear_session().await;
            Err(AuthError::NotAuthenticated)
        }
        Err(AuthError::TokenExpired) => {
            // Try to refresh tokens
            if session_manager.needs_refresh().await {
                // Implement token refresh logic
                Ok(())
            } else {
                session_manager.clear_session().await;
                Err(AuthError::TokenExpired)
            }
        }
        other => other,
    }
}
}

Best Practices

Security

  1. Use HTTPS only - Never transmit session data over unencrypted connections
  2. Secure storage - Store session files with appropriate file permissions
  3. Token rotation - Refresh tokens before expiration
  4. Cleanup on exit - Clear sessions when application terminates

Performance

  1. Auto-save carefully - Consider performance impact of frequent saves
  2. Session reuse - Reuse sessions across requests instead of recreating
  3. Batch updates - Disable auto-save for bulk operations, save manually
  4. Memory management - Clear unused sessions promptly

Reliability

  1. Handle network failures - Implement retry logic for session operations
  2. Validate before use - Always check session validity before API calls
  3. Graceful degradation - Handle missing or corrupted session files
  4. Monitor session health - Track session age and usage patterns

This comprehensive session management system provides robust, secure, and efficient handling of authentication state for the axiomtrade-rs client library.

OTP Verification

The OTP (One-Time Password) verification system in axiomtrade-rs provides both manual and automatic OTP handling for secure authentication with Axiom Trade. This system supports automatic OTP retrieval from email via IMAP, eliminating the need for manual intervention in automated trading systems.

Overview

The OTP verification flow consists of two main approaches:

  1. Manual OTP Entry - User manually enters the OTP code when prompted
  2. Automatic OTP Fetching - System automatically retrieves OTP from email via IMAP

Both approaches integrate seamlessly with the authentication system and handle retries, timeouts, and error recovery.

Manual OTP Entry

Manual OTP entry is the simplest approach and requires no additional setup beyond basic authentication credentials.

Basic Usage

use axiomtrade_rs::auth::AuthClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut auth_client = AuthClient::new()?;
    
    // The None parameter triggers manual OTP entry
    let tokens = auth_client.login(
        "your-email@domain.com",
        "your-password",
        None  // Will prompt for manual OTP entry
    ).await?;
    
    println!("Authentication successful!");
    Ok(())
}

Manual OTP Helper Function

You can also provide the OTP code directly if you have it from another source:

use std::io::{self, Write};

fn get_otp_from_user() -> Result<String, io::Error> {
    print!("Enter OTP code: ");
    io::stdout().flush()?;
    
    let mut otp = String::new();
    io::stdin().read_line(&mut otp)?;
    
    Ok(otp.trim().to_string())
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut auth_client = AuthClient::new()?;
    
    // Get OTP from user input
    let otp_code = get_otp_from_user()?;
    
    let tokens = auth_client.login(
        "your-email@domain.com",
        "your-password",
        Some(otp_code)
    ).await?;
    
    println!("Authentication successful!");
    Ok(())
}

Automatic OTP Fetching

Automatic OTP fetching eliminates manual intervention by retrieving OTP codes directly from your email via IMAP. This feature is essential for automated trading systems and production applications.

Prerequisites

Before enabling automatic OTP fetching, you need:

  1. An inbox.lv email account with IMAP enabled
  2. Axiom Trade configured to send OTP emails to your inbox.lv address
  3. Environment variables configured with IMAP credentials

Environment Configuration

Add these variables to your .env file:

# Axiom Trade Credentials
AXIOM_EMAIL=your_axiom_email@domain.com
AXIOM_PASSWORD=your_axiom_password

# inbox.lv IMAP Configuration
INBOX_LV_EMAIL=your_username@inbox.lv
INBOX_LV_PASSWORD=your_imap_password

Automatic OTP Usage

When environment variables are configured, the system automatically fetches OTP codes:

use axiomtrade_rs::auth::AuthClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load environment variables
    dotenvy::dotenv().ok();
    
    let mut auth_client = AuthClient::new()?;
    
    // Automatic OTP fetching when None is passed
    let tokens = auth_client.login(
        &std::env::var("AXIOM_EMAIL")?,
        &std::env::var("AXIOM_PASSWORD")?,
        None  // System will automatically fetch OTP from email
    ).await?;
    
    println!("Authentication successful with automatic OTP!");
    Ok(())
}

Advanced OTP Fetching

For more control over the OTP fetching process:

use axiomtrade_rs::email::otp_fetcher::{OtpFetcher, from_env};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create OTP fetcher from environment variables
    let otp_fetcher = from_env()?
        .ok_or("OTP fetcher not configured")?;
    
    // Wait for OTP with custom timeout and check interval
    if let Some(otp) = otp_fetcher.wait_for_otp(120, 5)? {
        println!("Retrieved OTP: {}", otp);
        
        // Use the OTP for authentication
        let mut auth_client = AuthClient::new()?;
        let tokens = auth_client.login(
            "your-email@domain.com",
            "your-password",
            Some(otp)
        ).await?;
        
        println!("Authentication successful!");
    } else {
        println!("OTP not received within timeout");
    }
    
    Ok(())
}

OTP Validation Flow

The OTP validation process follows this sequence:

  1. Initial Login Request - Send credentials to /login-password-v2
  2. OTP JWT Token - Receive temporary JWT token for OTP verification
  3. OTP Retrieval - Get OTP code (manual entry or automatic fetch)
  4. OTP Verification - Send OTP code to /login-otp with JWT token
  5. Token Receipt - Receive access and refresh tokens on success

Flow Diagram

[Credentials] → [login-password-v2] → [OTP JWT Token]
                                            ↓
[OTP Code] ← [Manual/Auto Fetch] ← [OTP Required]
     ↓
[login-otp] → [Access/Refresh Tokens]

Implementation Details

The authentication client handles the complete flow automatically:

#![allow(unused)]
fn main() {
// Internal flow (handled automatically by AuthClient)
async fn login_flow_example() -> Result<(), AuthError> {
    let mut client = AuthClient::new()?;
    
    // Step 1: Initial login - gets OTP JWT token
    let otp_jwt_token = client.login_step1(email, hashed_password).await?;
    
    // Step 2: Fetch OTP (automatic or manual)
    let otp_code = client.fetch_otp().await?;
    
    // Step 3: Verify OTP and get tokens
    let tokens = client.login_step2(&otp_jwt_token, &otp_code, email, hashed_password).await?;
    
    // Tokens are automatically saved by TokenManager
    Ok(())
}
}

Retry Logic

The OTP system includes comprehensive retry logic for robust operation:

Email Fetching Retries

#![allow(unused)]
fn main() {
// Automatic retry with exponential backoff
pub fn wait_for_otp(&self, timeout_seconds: u64, check_interval_seconds: u64) -> Result<Option<String>, Box<dyn Error>> {
    let start_time = std::time::Instant::now();
    let timeout_duration = std::time::Duration::from_secs(timeout_seconds);
    let check_interval = std::time::Duration::from_secs(check_interval_seconds);
    
    while start_time.elapsed() < timeout_duration {
        // Check for new OTP emails
        if let Some(otp) = self.fetchotp_recent(3)? {
            return Ok(Some(otp));
        }
        
        // Wait before next check
        std::thread::sleep(check_interval);
    }
    
    Ok(None) // Timeout reached
}
}

Authentication Retries

The authentication client automatically retries failed requests:

#![allow(unused)]
fn main() {
// Built-in retry logic for authentication requests
impl AuthClient {
    async fn login_with_retry(&mut self, email: &str, password: &str, max_retries: u32) -> Result<AuthTokens, AuthError> {
        let mut retries = 0;
        
        loop {
            match self.login(email, password, None).await {
                Ok(tokens) => return Ok(tokens),
                Err(AuthError::NetworkError(_)) if retries < max_retries => {
                    retries += 1;
                    println!("Login attempt {} failed, retrying...", retries);
                    tokio::time::sleep(tokio::time::Duration::from_secs(retries as u64)).await;
                }
                Err(e) => return Err(e),
            }
        }
    }
}
}

Multiple Endpoint Fallback

The system automatically tries different API endpoints on failure:

#![allow(unused)]
fn main() {
// Automatic endpoint rotation on failure
let endpoints = [
    "https://api2.axiom.trade",
    "https://api3.axiom.trade", 
    "https://api6.axiom.trade",
    // ... more endpoints
];

// Client automatically selects different endpoint on retry
}

Common Issues

IMAP Connection Issues

Problem: Connection to inbox.lv IMAP server fails

Symptoms:

  • "IMAP connection failed" errors
  • "Authentication failed" messages
  • Timeout errors connecting to mail.inbox.lv

Solutions:

  1. Verify IMAP is enabled: Wait 15 minutes after enabling IMAP in inbox.lv settings
  2. Check credentials: Use IMAP password, not web login password
  3. Test connection: Try logging into inbox.lv webmail to verify credentials
  4. Firewall check: Ensure port 993 (IMAPS) is not blocked
#![allow(unused)]
fn main() {
// Test IMAP connection manually
use imap::ClientBuilder;

async fn test_imap_connection() -> Result<(), Box<dyn std::error::Error>> {
    let tls = native_tls::TlsConnector::builder().build()?;
    let client = imap::connect(("mail.inbox.lv", 993), "mail.inbox.lv", &tls)?;
    
    let _session = client.login("your_email@inbox.lv", "your_imap_password")
        .map_err(|e| format!("IMAP login failed: {:?}", e))?;
    
    println!("IMAP connection successful!");
    Ok(())
}
}

OTP Email Not Found

Problem: System cannot find OTP emails in inbox

Symptoms:

  • "No OTP emails found" errors
  • "OTP not received within timeout" messages
  • Empty email search results

Solutions:

  1. Check email forwarding: Verify Axiom Trade sends OTP to inbox.lv address
  2. Check spam folder: OTP emails might be filtered as spam
  3. Verify email format: Ensure subject contains "Your Axiom security code is XXXXXX"
  4. Test email delivery: Send test email to inbox.lv to verify delivery
#![allow(unused)]
fn main() {
// Manual email search for debugging
use axiomtrade_rs::email::otp_fetcher::OtpFetcher;

async fn debug_email_search() -> Result<(), Box<dyn std::error::Error>> {
    let fetcher = OtpFetcher::new(
        "your_email@inbox.lv".to_string(),
        "your_imap_password".to_string()
    );
    
    // Check for any recent emails (not just OTP)
    println!("Searching for recent emails...");
    
    // This would require additional methods in the OtpFetcher implementation
    // to help debug email reception issues
    
    Ok(())
}
}

OTP Extraction Failures

Problem: OTP found in email but extraction fails

Symptoms:

  • "OTP extraction failed" errors
  • Retrieved empty or invalid OTP codes
  • Regex pattern matching failures

Solutions:

  1. Check email format: Verify actual email subject and body format
  2. Update patterns: Add new regex patterns if email format changed
  3. Manual verification: Check raw email content for OTP code location
#![allow(unused)]
fn main() {
// Debug OTP extraction
fn debug_otp_extraction(email_content: &str) {
    let patterns = vec![
        r"Your Axiom security code is[:\s]+(\d{6})",
        r"Your security code is[:\s]+(\d{6})",
        r"security code[:\s]+(\d{6})",
        r"<span[^>]*>(\d{6})</span>",
        r"<b>(\d{6})</b>",
        r"<strong>(\d{6})</strong>",
    ];
    
    for pattern in patterns {
        if let Ok(re) = regex::Regex::new(pattern) {
            if let Some(captures) = re.captures(email_content) {
                if let Some(otp) = captures.get(1) {
                    println!("Found OTP '{}' using pattern: {}", otp.as_str(), pattern);
                    return;
                }
            }
        }
    }
    
    println!("No OTP found in email content");
    println!("Email content preview: {}", &email_content[..std::cmp::min(200, email_content.len())]);
}
}

Authentication Timeout Issues

Problem: OTP verification takes too long or times out

Symptoms:

  • "Authentication timeout" errors
  • Slow OTP retrieval (>2 minutes)
  • Connection timeouts during verification

Solutions:

  1. Increase timeout: Extend OTP wait time for slow email delivery
  2. Reduce check interval: Check for emails more frequently
  3. Network check: Verify stable internet connection
  4. Server selection: Try different API endpoints
#![allow(unused)]
fn main() {
// Custom timeout configuration
async fn login_with_custom_timeout() -> Result<(), Box<dyn std::error::Error>> {
    let mut auth_client = AuthClient::new()?;
    
    // Configure longer timeout for OTP fetching
    if let Some(otp_fetcher) = auth_client.get_otp_fetcher() {
        // Wait up to 5 minutes, check every 10 seconds
        if let Some(otp) = otp_fetcher.wait_for_otp(300, 10)? {
            let tokens = auth_client.login(
                "email@domain.com",
                "password", 
                Some(otp)
            ).await?;
            println!("Authentication successful with extended timeout!");
        }
    }
    
    Ok(())
}
}

Token Management Issues

Problem: Token storage or refresh failures

Symptoms:

  • "Token not found" errors
  • "Token expired" messages
  • Authentication succeeds but tokens not saved

Solutions:

  1. Check file permissions: Ensure write access to token file location
  2. Verify token format: Check saved token file structure
  3. Manual token refresh: Implement custom token refresh logic
#![allow(unused)]
fn main() {
// Manual token management
use axiomtrade_rs::auth::{TokenManager, AuthTokens};

async fn manage_tokens_manually() -> Result<(), Box<dyn std::error::Error>> {
    let token_manager = TokenManager::new(Some(std::path::PathBuf::from(".axiom_tokens.json")));
    
    // Check for existing tokens
    if let Ok(Some(tokens)) = token_manager.get_tokens().await {
        if tokens.is_expired() {
            println!("Tokens expired, refreshing...");
            
            let mut auth_client = AuthClient::new()?;
            let new_access_token = auth_client.refresh_token(&tokens.refresh_token).await?;
            
            let updated_tokens = AuthTokens {
                access_token: new_access_token,
                refresh_token: tokens.refresh_token,
                expires_at: Some(chrono::Utc::now() + chrono::Duration::hours(1)),
            };
            
            token_manager.set_tokens(updated_tokens).await?;
            println!("Tokens refreshed successfully!");
        } else {
            println!("Tokens are still valid");
        }
    } else {
        println!("No existing tokens found, need to login");
    }
    
    Ok(())
}
}

Best Practices

Security Considerations

  1. Dedicated Email: Use inbox.lv account only for OTP purposes
  2. Environment Variables: Store credentials in .env file, never in code
  3. File Permissions: Secure token storage files with appropriate permissions
  4. Credential Rotation: Regularly update IMAP passwords

Performance Optimization

  1. Connection Pooling: Reuse IMAP connections when possible
  2. Caching: Cache successful configurations to reduce setup time
  3. Async Operations: Use async/await for all network operations
  4. Timeout Tuning: Optimize timeout values based on email delivery speed

Error Handling

  1. Graceful Degradation: Fall back to manual OTP when automatic fails
  2. Detailed Logging: Log OTP retrieval steps for debugging
  3. User Feedback: Provide clear status messages during OTP process
  4. Retry Strategies: Implement exponential backoff for failed requests

Production Deployment

  1. Health Checks: Monitor OTP system health and email delivery
  2. Alerting: Set up alerts for OTP failures or slow delivery
  3. Backup Methods: Have manual OTP fallback for system maintenance
  4. Documentation: Maintain setup documentation for team members

Testing Your Setup

Use the provided test example to verify your OTP configuration:

cargo run --example test_auto_otp

This test will:

  1. Verify environment variable configuration
  2. Test IMAP connection to inbox.lv
  3. Attempt full authentication flow with automatic OTP
  4. Provide detailed diagnostic information on failures

The test output will guide you through any configuration issues and provide specific troubleshooting steps for your setup.

Portfolio Management

The portfolio management system in axiomtrade-rs provides comprehensive access to wallet balances, token holdings, and portfolio analytics. This module allows you to query single wallets, perform batch operations across multiple addresses, and retrieve detailed portfolio summaries.

Overview

The PortfolioClient handles all portfolio-related operations including:

  • Single wallet balance queries - Get detailed balance information for individual wallets
  • Batch balance operations - Query multiple wallets simultaneously for efficiency
  • Portfolio summaries - Comprehensive portfolio analytics with performance metrics
  • Token account analysis - Detailed token holdings and distribution analysis

Quick Start

#![allow(unused)]
fn main() {
use axiomtrade_rs::api::portfolio::PortfolioClient;

// Create portfolio client
let mut portfolio_client = PortfolioClient::new()?;

// Get single wallet balance
let balance = portfolio_client.get_balance("DYw8jCTfwHNRJhhmFcbXvVDTqWMEVFBX6ZKUmG5CNSKK").await?;
println!("SOL Balance: {:.6}", balance.sol_balance);
println!("Total Value: ${:.2}", balance.total_value_usd);
}

Getting Wallet Balances

Single Wallet Balance

Retrieve the complete balance information for a single Solana wallet address.

#![allow(unused)]
fn main() {
let wallet_address = "DYw8jCTfwHNRJhhmFcbXvVDTqWMEVFBX6ZKUmG5CNSKK";
let balance = portfolio_client.get_balance(wallet_address).await?;

println!("SOL Balance: {:.6} SOL", balance.sol_balance);
println!("Total USD Value: ${:.2}", balance.total_value_usd);
println!("Token Count: {}", balance.token_balances.len());

// Access individual token balances
for (mint_address, token) in &balance.token_balances {
    println!("{} ({}): {} tokens (${:.2})", 
        token.symbol, 
        token.name,
        token.ui_amount, 
        token.value_usd
    );
}
}

Response Structure:

#![allow(unused)]
fn main() {
WalletBalance {
    sol_balance: f64,                              // SOL amount in native units
    token_balances: HashMap<String, TokenBalance>, // Token holdings by mint address
    total_value_usd: f64,                         // Total portfolio value in USD
}

TokenBalance {
    mint_address: String,     // Token mint address
    symbol: String,           // Token symbol (e.g., "USDC")
    name: String,             // Full token name
    amount: f64,              // Raw token amount
    decimals: u8,             // Token decimal places
    ui_amount: f64,           // Human-readable amount
    value_usd: f64,           // USD value of holding
    price_per_token: f64,     // Current token price
}
}

Batch Balance Queries

For applications managing multiple wallets, batch queries provide significant performance improvements by fetching all balances in a single API call.

Basic Batch Query

#![allow(unused)]
fn main() {
let wallet_addresses = vec![
    "DYw8jCTfwHNRJhhmFcbXvVDTqWMEVFBX6ZKUmG5CNSKK".to_string(),
    "5FHwkrdxntdK24hgQU8qgBjn35Y1zwhz1GZwCkP2UJnM".to_string(),
    "7xLk17EQQ5KLDLDe44wCmupJKJjTGd8hs3eSVVhCx932".to_string(),
];

let batch_response = portfolio_client.get_batch_balance(&wallet_addresses).await?;

println!("Retrieved {} wallet balances", batch_response.balances.len());

let mut total_value = 0.0;
for (address, balance) in &batch_response.balances {
    println!("Wallet {}: {:.6} SOL (${:.2})", 
        &address[..8], 
        balance.sol_balance, 
        balance.total_value_usd
    );
    total_value += balance.total_value_usd;
}

println!("Combined portfolio value: ${:.2}", total_value);
}

Advanced Batch Analysis

#![allow(unused)]
fn main() {
let batch_response = portfolio_client.get_batch_balance(&wallet_addresses).await?;

// Analyze token distribution across wallets
let mut token_counts = HashMap::new();
let mut token_values = HashMap::new();

for (address, balance) in &batch_response.balances {
    for token in balance.token_balances.values() {
        *token_counts.entry(token.symbol.clone()).or_insert(0) += 1;
        *token_values.entry(token.symbol.clone()).or_insert(0.0) += token.value_usd;
    }
}

// Find most common tokens
let mut sorted_tokens: Vec<_> = token_counts.iter().collect();
sorted_tokens.sort_by(|a, b| b.1.cmp(a.1));

for (token, count) in sorted_tokens.iter().take(5) {
    let total_value = token_values.get(*token).unwrap_or(&0.0);
    println!("{} - held by {} wallets, total value: ${:.2}", 
        token, count, total_value);
}
}

Batch Response Structure:

#![allow(unused)]
fn main() {
BatchBalanceResponse {
    balances: HashMap<String, WalletBalance>, // Wallet address -> balance data
    timestamp: i64,                          // Query timestamp
}
}

Portfolio Summary

The portfolio summary provides comprehensive analytics including performance metrics, top positions, and transaction history.

Getting Portfolio Summary

#![allow(unused)]
fn main() {
let wallet_addresses = vec![
    "DYw8jCTfwHNRJhhmFcbXvVDTqWMEVFBX6ZKUmG5CNSKK".to_string(),
    "5FHwkrdxntdK24hgQU8qgBjn35Y1zwhz1GZwCkP2UJnM".to_string(),
];

let portfolio = portfolio_client.get_portfolio_summary(&wallet_addresses).await?;

// Overall balance statistics
println!("Total Value: {:.4} SOL", portfolio.balance_stats.total_value_sol);
println!("Available Balance: {:.4} SOL", portfolio.balance_stats.available_balance_sol);
println!("Unrealized PnL: {:.4} SOL", portfolio.balance_stats.unrealized_pnl_sol);

// Performance metrics
println!("1 Day PnL: {:.4} SOL", portfolio.performance_metrics.one_day.total_pnl);
println!("7 Day PnL: {:.4} SOL", portfolio.performance_metrics.seven_day.total_pnl);
println!("30 Day PnL: {:.4} SOL", portfolio.performance_metrics.thirty_day.total_pnl);
println!("All Time PnL: {:.4} SOL", portfolio.performance_metrics.all_time.total_pnl);
}

Analyzing Top Positions

#![allow(unused)]
fn main() {
// Display top holdings
for (i, position) in portfolio.top_positions.iter().take(10).enumerate() {
    println!("{}. {} ({})", 
        i + 1, 
        position.symbol.as_deref().unwrap_or("Unknown"), 
        position.name.as_deref().unwrap_or("Unknown")
    );
    
    if let Some(amount) = position.amount {
        println!("   Amount: {:.4}", amount);
    }
    if let Some(value_usd) = position.value_usd {
        println!("   Value: ${:.2}", value_usd);
    }
    if let Some(pnl_percent) = position.pnl_percent {
        println!("   PnL: {}{:.2}%", 
            if pnl_percent >= 0.0 { "+" } else { "" },
            pnl_percent
        );
    }
}
}

Transaction History

#![allow(unused)]
fn main() {
// Recent transactions
for tx in portfolio.transactions.iter().take(10) {
    if let (Some(symbol), Some(tx_type), Some(amount), Some(value_usd)) = 
        (&tx.symbol, &tx.transaction_type, tx.amount, tx.value_usd) {
        println!("{} {} {} for ${:.2}", tx_type, amount, symbol, value_usd);
        
        if let Some(timestamp) = tx.timestamp {
            let datetime = chrono::DateTime::from_timestamp(timestamp / 1000, 0)
                .unwrap_or_default();
            println!("   Time: {}", datetime.format("%Y-%m-%d %H:%M:%S UTC"));
        }
    }
}
}

Portfolio Monitoring

For real-time portfolio tracking, you can implement continuous monitoring with change detection.

Basic Monitoring Loop

#![allow(unused)]
fn main() {
use std::time::{Duration, Instant};
use tokio::time::sleep;

let mut last_portfolio = portfolio_client.get_portfolio_summary(&wallet_addresses).await?;
let initial_value = last_portfolio.balance_stats.total_value_sol;

loop {
    sleep(Duration::from_secs(30)).await;
    
    match portfolio_client.get_portfolio_summary(&wallet_addresses).await {
        Ok(current_portfolio) => {
            // Detect changes
            let value_change = current_portfolio.balance_stats.total_value_sol - 
                              last_portfolio.balance_stats.total_value_sol;
            
            if value_change.abs() > 0.001 {

Best Practices

Efficient Batch Operations

  • Use batch queries for multiple wallets to reduce API calls
  • Limit batch size to reasonable numbers (typically 50-100 wallets)
  • Implement proper error handling for partial failures

Performance Optimization

  • Cache balance data when possible to reduce API load
  • Use appropriate update intervals for monitoring (30-60 seconds minimum)
  • Implement exponential backoff for failed requests

Error Recovery

  • Handle authentication errors by refreshing tokens
  • Implement retry logic for transient network errors
  • Validate wallet addresses before making API calls

Memory Management

  • Clean up historical data periodically in monitoring applications
  • Avoid storing excessive amounts of portfolio history in memory
  • Use streaming or pagination for large datasets

This portfolio management system provides comprehensive tools for tracking and analyzing Solana wallet portfolios, from simple balance queries to advanced risk analysis and real-time monitoring capabilities.

use axiomtrade_rs::api::trading::TradingClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize trading client
    let mut trading_client = TradingClient::new()?;
    
    // Example: Buy USDC with SOL
    let usdc_mint = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v";
    let amount_sol = 0.1;
    
    let order = trading_client
        .buy_token(usdc_mint, amount_sol, Some(1.0))
        .await?;
    
    println!("Buy order executed: {}", order.signature);
    Ok(())
}

Buy Operations

Buy operations allow you to purchase tokens using SOL as the base currency. The API handles routing through the best available liquidity sources.

        0.1,                                              // 0.1 SOL
        Some(1.0)                                         // 1% slippage
    )
    .await?;

Price Quotes

Always get a quote before executing trades to understand pricing, fees, and market impact.

Getting Accurate Quotes

#![allow(unused)]
fn main() {
// Get a comprehensive quote
let quote = trading_client
    .get_quote(
        "So11111111111111111111111111111111111111112",   // SOL
        "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", // USDC
        1.0,        // 1 SOL
        Some(0.5)   // 0.5% slippage
    )
    .await?;

println!("Quote Analysis:");
println!("  Input: {} SOL", quote.in_amount);
println!("  Output: {} USDC", quote.out_amount);
println!("  Exchange rate: {} USDC per SOL", quote.out_amount / quote.in_amount);
println!("  Price impact: {:.3}%", quote.price_impact);
println!("  Platform fee: {} SOL", quote.fee);
}

Quote Response Structure

#![allow(unused)]
fn main() {
pub struct QuoteResponse {
    pub input_mint: String,     // Source token mint
    pub output_mint: String,    // Destination token mint
    pub in_amount: f64,         // Input amount
    pub out_amount: f64,        // Expected output amount
    pub price_impact: f64,      // Price impact percentage
    pub fee: f64,               // Total fees
    pub route: Vec<RouteStep>,  // Routing information
}

pub struct RouteStep {
    pub amm: String,            // AMM/DEX name (e.g., "Raydium", "Orca")
    pub input_mint: String,     // Input token for this step
    pub output_mint: String,    // Output token for this step
    pub in_amount: f64,         // Input amount for this step
    pub out_amount: f64,        // Output amount for this step
    pub fee_amount: f64,        // Fee for this step
}
}

Slippage and MEV Protection

Axiom Trade includes built-in protection against slippage and MEV attacks.

Understanding Slippage

Slippage occurs when the actual execution price differs from the expected price due to market movement or liquidity constraints.

#![allow(unused)]
fn main() {
// Conservative slippage for large trades
let large_trade_slippage = 0.1; // 0.1% for liquid tokens

// Standard slippage for normal trades
let normal_slippage = 0.5; // 0.5%

// Higher slippage for small/illiquid tokens
let high_slippage = 2.0; // 2.0%

// Example with different slippage scenarios
async fn execute_trade_with_slippage_analysis(
    client: &mut TradingClient,
    token_mint: &str,
    amount: f64
) -> Result<(), Box<dyn std::error::Error>> {
    
    // Test different slippage levels
    let slippage_levels = vec![0.1, 0.5, 1.0, 2.0];
    
    for slippage in slippage_levels {
        match client.get_quote(
            "So11111111111111111111111111111111111111112",
            token_mint,
            amount,
            Some(slippage)
        ).await {
            Ok(quote) => {
                println!("Slippage {:.1}%: Output {} tokens, Impact {:.3}%", 
                    slippage, quote.out_amount, quote.price_impact);
            }
            Err(e) => {
                println!("Slippage {:.1}%: Failed - {}", slippage, e);
            }
        }
    }
    
    // Execute with conservative slippage
    let order = client.buy_token(token_mint, amount, Some(0.5)).await?;
    println!("Trade executed with 0.5% slippage tolerance");
    
    Ok(())
}
}

MEV Protection

Axiom Trade automatically implements MEV protection strategies:

  1. Private Mempool: Transactions are routed through private mempools
  2. Bundle Protection: Orders are bundled to prevent front-running
  3. Optimal Timing: Executes at optimal times to minimize MEV exposure
  4. Route Optimization: Uses routes that minimize MEV vulnerability
#![allow(unused)]
fn main() {
// MEV protection is automatically enabled
// No additional configuration required

let order = trading_client
    .buy_token(
        "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v",
        1.0,
        Some(0.5)
    )
    .await?;

// The system automatically:
// - Routes through protected channels
// - Uses optimal AMM combinations
// - Implements timing strategies
// - Protects against sandwich attacks
}

Order Types and Parameters

Order Status Types

#![allow(unused)]
fn main() {
pub enum OrderStatus {
    Success,    // Order completed successfully
    Failed,     // Order failed to execute
    Pending,    // Order is being processed
    Cancelled,  // Order was cancelled
}
}

Order Response Structure

#![allow(unused)]
fn main() {
pub struct OrderResponse {
    pub signature: String,          // Transaction signature
    pub status: OrderStatus,        // Order status
    pub transaction_type: OrderType, // Buy, Sell, or Swap
    pub token_mint: String,         // Token mint address
    pub amount_in: f64,             // Input amount
    pub amount_out: f64,            // Output amount received
    pub price_per_token: f64,       // Effective price per token
    pub total_sol: f64,             // Total SOL involved
    pub fee: f64,                   // Transaction fee
    pub timestamp: i64,             // Execution timestamp
}
}

Priority Fees

Priority fees help ensure faster transaction processing during network congestion.

#![allow(unused)]
fn main() {
// Auto-calculated priority fee (recommended)
let order = trading_client
    .buy_token(token_mint, amount, Some(1.0))
    .await?;

// Priority fees are automatically adjusted based on:
// - Current network congestion
// - Transaction urgency
// - Historical gas patterns
// - Market volatility
}

Trading Limits

Understanding and respecting trading limits ensures consistent API access.

Getting Current Limits

#![allow(unused)]
fn main() {
let limits = trading_client.get_trading_limits().await?;

println!("Trading Limits:");
println!("  Minimum SOL per trade: {}", limits.min_sol_amount);
println!("  Maximum SOL per trade: {}", limits.max_sol_amount);
println!("  Maximum slippage: {}%", limits.max_slippage_percent);
println!("  Default slippage: {}%", limits.default_slippage_percent);
println!("  Priority fee: {} lamports", limits.priority_fee_lamports);
}

Limit Structure

#![allow(unused)]
fn main() {
pub struct TradingLimits {
    pub min_sol_amount: f64,           // Minimum SOL per trade (0.01)
    pub max_sol_amount: f64,           // Maximum SOL per trade (100.0)
    pub max_slippage_percent: f64,     // Maximum allowed slippage (50.0%)
    pub default_slippage_percent: f64, // Default slippage (5.0%)
    pub priority_fee_lamports: u64,    // Default priority fee (5000)
}
}

Respecting Limits

#![allow(unused)]
fn main() {
async fn safe_trade_execution(
    client: &mut TradingClient,
    token_mint: &str,
    amount: f64,
    slippage: f64
) -> Result<OrderResponse, Box<dyn std::error::Error>> {
    
    // Check limits before trading
    let limits = client.get_trading_limits().await?;
    
    // Validate amount
    if amount < limits.min_sol_amount {
        return Err(format!("Amount {} below minimum {}", 
            amount, limits.min_sol_amount).into());
    }
    
    if amount > limits.max_sol_amount {
        return Err(format!("Amount {} exceeds maximum {}", 
            amount, limits.max_sol_amount).into());
    }
    
    // Validate slippage
    let safe_slippage = if slippage > limits.max_slippage_percent {
        limits.default_slippage_percent
    } else {
        slippage
    };
    
    // Execute trade
    let order = client.buy_token(token_mint, amount, Some(safe_slippage)).await?;
    Ok(order)
}
}

Transaction Simulation

Simulate transactions before execution to verify expected outcomes.

Basic Simulation

#![allow(unused)]
fn main() {
// Note: You would typically get the transaction data from a quote or prepare step
let transaction_base64 = "base64_encoded_transaction_data";

let simulation = trading_client
    .simulate_transaction(&transaction_base64)
    .await?;

if simulation.success {
    println!("Simulation successful!");
    println!("Compute units consumed: {}", simulation.units_consumed);
    
    // Analyze logs for detailed information
    for log in &simulation.logs {
        if log.contains("Program log:") {
            println!("  {}", log);
        }
    }
} else {
    println!("Simulation failed: {}", 
        simulation.error.unwrap_or_else(|| "Unknown error".to_string()));
}
}

Simulation Response Structure

#![allow(unused)]
fn main() {
pub struct TransactionSimulation {
    pub success: bool,              // Whether simulation succeeded
    pub error: Option<String>,      // Error message if failed
    pub logs: Vec<String>,          // Transaction logs
    pub units_consumed: u64,        // Compute units used
}
}

Error Handling

Comprehensive error handling for robust trading applications.

Error Types

#![allow(unused)]
fn main() {
pub enum TradingError {
    AuthError(AuthError),           // Authentication issues
    NetworkError(reqwest::Error),   // Network connectivity problems
    InvalidTokenMint(String),       // Invalid token address
    InsufficientBalance(String),    // Not enough tokens/SOL
    SlippageExceeded(String),       // Slippage tolerance exceeded
    TransactionFailed(String),      // Transaction execution failed
    ApiError(String),               // General API errors
    ParsingError(String),           // Data parsing issues
}
}

Error Handling Examples

#![allow(unused)]
fn main() {
use axiomtrade_rs::api::trading::TradingError;

async fn handle_trading_errors(
    client: &mut TradingClient
) -> Result<(), Box<dyn std::error::Error>> {
    
    match client.buy_token("invalid_mint", 0.1, Some(1.0)).await {
        Ok(order) => {
            println!("Trade successful: {}", order.signature);
        }
        Err(TradingError::InvalidTokenMint(msg)) => {
            println!("Invalid token address: {}", msg);
        }
        Err(TradingError::InsufficientBalance(msg)) => {
            println!("Insufficient balance: {}", msg);
        }
        Err(TradingError::SlippageExceeded(msg)) => {
            println!("Slippage exceeded: {}", msg);
            // Retry with higher slippage tolerance
        }
        Err(TradingError::NetworkError(e)) => {
            println!("Network error: {}", e);
            // Implement retry logic
        }
        Err(e) => {
            println!("Other error: {}", e);
        }
    }
    
    Ok(())
}
}

Retry Logic

#![allow(unused)]
fn main() {
use tokio::time::{sleep, Duration};

async fn execute_with_retry(
    client: &mut TradingClient,
    token_mint: &str,
    amount: f64,
    max_retries: u32
) -> Result<OrderResponse, TradingError> {
    
    let mut attempts = 0;
    
    loop {
        match client.buy_token(token_mint, amount, Some(1.0)).await {
            Ok(order) => return Ok(order),
            Err(TradingError::NetworkError(_)) if attempts < max_retries => {
                attempts += 1;
                println!("Network error, retrying ({}/{})", attempts, max_retries);
                sleep(Duration::from_millis(1000 * attempts as u64)).await;
            }
            Err(TradingError::SlippageExceeded(_)) if attempts < max_retries => {
                attempts += 1;
                let higher_slippage = 1.0 + (0.5 * attempts as f64);
                println!("Retrying with {}% slippage", higher_slippage);
                
                match client.buy_token(token_mint, amount, Some(higher_slippage)).await {
                    Ok(order) => return Ok(order),
                    Err(e) => {
                        if attempts >= max_retries {
                            return Err(e);
                        }
                    }
                }
            }
            Err(e) => return Err(e),
        }
    }
}
}

Best Practices

1. Always Get Quotes First

#![allow(unused)]
fn main() {
// Good practice: Check quote before trading
let quote = trading_client.get_quote(from_mint, to_mint, amount, Some(1.0)).await?;

if quote.price_impact < 2.0 {  // Acceptable price impact
    let order = trading_client.swap_tokens(from_mint, to_mint, amount, Some(1.0)).await?;
}
}

2. Use Appropriate Slippage

#![allow(unused)]
fn main() {
// Slippage guidelines by token type
let slippage = match token_type {
    "major" => 0.1,    // BTC, ETH, SOL, USDC - very liquid
    "popular" => 0.5,  // Popular tokens with good liquidity
    "standard" => 1.0, // Standard tokens
    "small" => 2.0,    // Smaller tokens with less liquidity
    _ => 5.0,          // Very small or new tokens
};
}

3. Implement Proper Error Handling

#![allow(unused)]
fn main() {
async fn robust_trading_function(
    client: &mut TradingClient,
    token_mint: &str,
    amount: f64
) -> Result<String, String> {
    
    // Validate inputs
    if amount <= 0.0 {
        return Err("Amount must be positive".to_string());
    }
    
    // Check trading limits
    let limits = client.get_trading_limits().await
        .map_err(|e| format!("Failed to get limits: {}", e))?;
    
    if amount < limits.min_sol_amount || amount > limits.max_sol_amount {
        return Err(format!("Amount {} outside limits [{}, {}]", 
            amount, limits.min_sol_amount, limits.max_sol_amount));
    }
    
    // Get quote first
    let quote = client.get_quote(
        "So11111111111111111111111111111111111111112",
        token_mint,
        amount,
        Some(1.0)
    ).await.map_err(|e| format!("Failed to get quote: {}", e))?;
    
    // Check price impact
    if quote.price_impact > 5.0 {
        return Err(format!("Price impact too high: {:.2}%", quote.price_impact));
    }
    
    // Execute trade
    let order = client.buy_token(token_mint, amount, Some(1.0)).await
        .map_err(|e| format!("Trade failed: {}", e))?;
    
    Ok(order.signature)
}
}

4. Monitor Transaction Status

#![allow(unused)]
fn main() {
async fn execute_and_monitor(
    client: &mut TradingClient,
    token_mint: &str,
    amount: f64
) -> Result<(), Box<dyn std::error::Error>> {
    
    let order = client.buy_token(token_mint, amount, Some(1.0)).await?;
    
    match order.status {
        OrderStatus::Success => {
            println!("✅ Trade completed successfully");
            println!("   Signature: {}", order.signature);
            println!("   Tokens received: {}", order.amount_out);
            println!("   Fee paid: {}", order.fee);
        }
        OrderStatus::Pending => {
            println!("⏳ Trade is pending confirmation");
            println!("   Monitor signature: {}", order.signature);
        }
        OrderStatus::Failed => {
            println!("❌ Trade failed");
            return Err("Trade execution failed".into());
        }
        OrderStatus::Cancelled => {
            println!("🚫 Trade was cancelled");
        }
    }
    
    Ok(())
}
}

5. Implement Rate Limiting

#![allow(unused)]
fn main() {
use tokio::time::{sleep, Duration, Instant};

struct RateLimiter {
    last_request: Instant,
    min_interval: Duration,
}

impl RateLimiter {
    fn new(requests_per_second: f64) -> Self {
        Self {
            last_request: Instant::now(),
            min_interval: Duration::from_secs_f64(1.0 / requests_per_second),
        }
    }
    
    async fn wait_if_needed(&mut self) {
        let elapsed = self.last_request.elapsed();
        if elapsed < self.min_interval {
            sleep(self.min_interval - elapsed).await;
        }
        self.last_request = Instant::now();
    }
}

// Usage
let mut rate_limiter = RateLimiter::new(2.0); // 2 requests per second

for trade in trades {
    rate_limiter.wait_if_needed().await;
    let result = trading_client.buy_token(&trade.mint, trade.amount, Some(1.0)).await;
    // Handle result...
}
}

Security Considerations

1. Token Validation

#![allow(unused)]
fn main() {
fn validate_token_mint(mint: &str) -> Result<(), String> {
    // Check length
    if mint.len() < 32 || mint.len() > 44 {
        return Err("Invalid mint address length".to_string());
    }
    
    // Check characters
    if !mint.chars().all(|c| c.is_ascii_alphanumeric()) {
        return Err("Invalid characters in mint address".to_string());
    }
    
    // Add known token validation
    let known_scam_tokens = vec![
        // Add known scam token addresses
    ];
    
    if known_scam_tokens.contains(&mint) {
        return Err("Token flagged as potential scam".to_string());
    }
    
    Ok(())
}
}

2. Amount Validation

#![allow(unused)]
fn main() {
fn validate_trade_amount(amount: f64, balance: f64) -> Result<(), String> {
    if amount <= 0.0 {
        return Err("Amount must be positive".to_string());
    }
    
    if amount.is_nan() || amount.is_infinite() {
        return Err("Invalid amount value".to_string());
    }
    
    if amount > balance * 0.95 {  // Keep 5% buffer
        return Err("Amount too close to total balance".to_string());
    }
    
    Ok(())
}
}

3. Slippage Protection

#![allow(unused)]
fn main() {
fn calculate_safe_slippage(
    amount: f64,
    token_liquidity: f64,
    market_volatility: f64
) -> f64 {
    let base_slippage = 0.5; // 0.5% base
    
    // Adjust for trade size relative to liquidity
    let size_impact = (amount / token_liquidity) * 100.0;
    let size_adjustment = if size_impact > 1.0 { size_impact } else { 0.0 };
    
    // Adjust for market volatility
    let volatility_adjustment = market_volatility * 0.5;
    
    // Cap at reasonable maximum
    let total_slippage = base_slippage + size_adjustment + volatility_adjustment;
    total_slippage.min(5.0) // Never exceed 5%
}
}

This comprehensive guide covers all aspects of trading operations with the Axiom Trade API. Always test with small amounts first and implement proper error handling and security measures in production applications.

Market Data

The Market Data API provides comprehensive access to real-time and historical market information for Solana tokens. This includes trending tokens, price feeds, token analysis, market statistics, and search functionality.

Overview

The MarketDataClient offers a complete suite of market data operations:

  • Trending Tokens: Get tokens trending across different timeframes
  • Token Information: Detailed token metadata and analysis
  • Price Feeds: Real-time and historical price data
  • Market Statistics: Overall market metrics and trends
  • Token Search: Find tokens by name, symbol, or address
  • Chart Data: OHLCV candle data for technical analysis

Quick Start

use axiomtrade_rs::api::market_data::MarketDataClient;
use axiomtrade_rs::models::market::TimePeriod;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut client = MarketDataClient::new()?;
    
    // Get trending tokens
    let trending = client.get_trending_tokens(TimePeriod::TwentyFourHours).await?;
    
    println!("Top trending token: {} - {}", 
        trending[0].symbol, 
        trending[0].name
    );
    
    Ok(())
}

    }
    Err(MarketDataError::ApiError(msg)) => {
        println!("API error: {}", msg);
    }
    Err(e) => {
        println!("Unexpected error: {}", e);
    }
}
}

Complete Example

Here's a comprehensive example showing various market data operations:

use axiomtrade_rs::models::market::{TimePeriod, ChartTimeframe};

#[tokio::main]

        println!("\n=== CHART DATA ===");
        let chart = client.get_token_chart(
            &token_info.mint_address,
            ChartTimeframe::OneHour,
            Some(5)
        ).await?;
        
        println!("Recent candles:");
        for candle in &chart.candles {
            println!("  OHLC: {:.6}/{:.6}/{:.6}/{:.6}", 
                candle.open, 
                candle.high, 
                candle.low,

Best Practices

Rate Limiting

The API includes built-in rate limiting. For high-frequency applications:

#![allow(unused)]
fn main() {
use tokio::time::{sleep, Duration};

// Add delays between requests for bulk operations
for symbol in token_symbols {
    let info = client.get_token_info(&symbol).await?;
    // Process info...
    
    sleep(Duration::from_millis(100)).await; // Prevent rate limiting
}
}

Error Recovery

Implement retry logic for network failures:

#![allow(unused)]
fn main() {
use tokio::time::{sleep, Duration};

async fn get_trending_with_retry(
    client: &mut MarketDataClient,
    period: TimePeriod,
    max_retries: u32
) -> Result<Vec<TrendingToken>, MarketDataError> {
    for attempt in 0..max_retries {
        match client.get_trending_tokens(period.clone()).await {
            Ok(tokens) => return Ok(tokens),
            Err(MarketDataError::NetworkError(_)) if attempt < max_retries - 1 => {
                sleep(Duration::from_millis(1000 * (attempt + 1) as u64)).await;
                continue;
            }
            Err(e) => return Err(e),
        }
    }
    
    unreachable!()
}
}

Batch Operations

Use batch endpoints when possible for better performance:

#![allow(unused)]
fn main() {
// Instead of multiple individual calls
// let price1 = client.get_token_price(mint1).await?;
// let price2 = client.get_token_price(mint2).await?;

// Use batch endpoint
let mints = vec![mint1.to_string(), mint2.to_string()];
let prices = client.get_batch_prices(&mints).await?;
}

Data Validation

Always validate mint addresses before API calls:

#![allow(unused)]
fn main() {
fn is_valid_mint_address(address: &str) -> bool {
    address.len() >= 32 && 
    address.len() <= 44 && 
    address.chars().all(|c| c.is_ascii_alphanumeric())
}

if is_valid_mint_address(&mint_address) {
    let price = client.get_token_price(&mint_address).await?;
} else {
    println!("Invalid mint address format");
}
}

The Market Data API provides comprehensive access to Solana token market information, enabling developers to build sophisticated trading applications, market analysis tools, and portfolio management systems.

WebSocket Streaming

The Axiom Trade Rust client provides comprehensive WebSocket support for real-time data streaming. The WebSocket module handles authentication, connection management, automatic reconnection, and provides a flexible message handling system.

Overview

The WebSocket implementation consists of three main components:

  • WebSocketClient: Core client for managing connections and subscriptions
  • MessageHandler: Trait for processing incoming messages
  • Message Types: Structured data types for different streaming data

Basic WebSocket Connection

Setting Up a Connection

use axiomtrade_rs::websocket::{WebSocketClient, MessageHandler, WebSocketMessage};
use async_trait::async_trait;
use std::sync::Arc;

// Create a message handler
struct MyMessageHandler;

#[async_trait]
impl MessageHandler for MyMessageHandler {
    async fn handle_message(&self, message: WebSocketMessage) {
        match message {
            WebSocketMessage::MarketUpdate(update) => {
                println!("Market Update: {} - ${:.6}", update.symbol, update.price_usd);
            }
            _ => {}
        }
    }

    async fn on_connected(&self, session_id: String) {
        println!("Connected with session: {}", session_id);
    }

    async fn on_disconnected(&self, reason: String) {
        println!("Disconnected: {}", reason);
    }

    async fn on_error(&self, error: String) {
        println!("Error: {}", error);
    }
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create WebSocket client
    let handler = Arc::new(MyMessageHandler);
    let mut ws_client = WebSocketClient::new(handler)?;
    
    // Connect to WebSocket
    ws_client.connect().await?;
    
    // Subscribe to data feeds
    ws_client.subscribe_new_tokens().await?;
    
    // Keep connection alive
    tokio::time::sleep(std::time::Duration::from_secs(30)).await;
    
    // Disconnect gracefully
    ws_client.disconnect().await;
    
    Ok(())
}

Regional Connection Options

The WebSocket client supports multiple regional endpoints for optimal latency:

#![allow(unused)]
fn main() {
use axiomtrade_rs::websocket::{WebSocketClient, Region};

// Create client with specific region
let handler = Arc::new(MyMessageHandler);
let mut ws_client = WebSocketClient::with_region(handler, Region::USWest)?;

// Available regions:
// - Region::USWest
// - Region::USCentral  
// - Region::USEast
// - Region::EUWest
// - Region::EUCentral
// - Region::EUEast
// - Region::Asia
// - Region::Australia
// - Region::Global (default)
}

MessageHandler Trait Implementation

The MessageHandler trait defines how your application processes incoming WebSocket messages:

#![allow(unused)]
fn main() {
#[async_trait]
pub trait MessageHandler: Send + Sync {
    /// Handles incoming WebSocket messages
    async fn handle_message(&self, message: WebSocketMessage);
    
    /// Called when connection is established
    async fn on_connected(&self, session_id: String);
    
    /// Called when connection is lost
    async fn on_disconnected(&self, reason: String);
    
    /// Called when an error occurs
    async fn on_error(&self, error: String);
}
}

Advanced Message Handler Example

#![allow(unused)]
fn main() {
use tokio::sync::RwLock;
use std::collections::HashMap;

struct AdvancedMessageHandler {
    price_data: Arc<RwLock<HashMap<String, f64>>>,
    order_book: Arc<RwLock<HashMap<String, OrderBookData>>>,
}

impl AdvancedMessageHandler {
    fn new() -> Self {
        Self {
            price_data: Arc::new(RwLock::new(HashMap::new())),
            order_book: Arc::new(RwLock::new(HashMap::new())),
        }
    }
    
    async fn get_latest_price(&self, token: &str) -> Option<f64> {
        self.price_data.read().await.get(token).copied()
    }
}

#[async_trait]
impl MessageHandler for AdvancedMessageHandler {
    async fn handle_message(&self, message: WebSocketMessage) {
        match message {
            WebSocketMessage::MarketUpdate(update) => {
                // Store price data
                let mut prices = self.price_data.write().await;
                prices.insert(update.symbol.clone(), update.price_usd);
                
                // Process price alerts
                if update.price_change_24h > 10.0 {
                    println!("🚀 {} is up {:.2}% in 24h!", 
                        update.symbol, update.price_change_24h);
                }
            }
            
            WebSocketMessage::OrderUpdate(order) => {
                println!("Order {} status: {:?}", order.order_id, order.status);
                
                if let Some(tx_hash) = &order.transaction_hash {
                    println!("Transaction: {}", tx_hash);
                }
            }
            
            WebSocketMessage::TradeUpdate(trade) => {
                println!("Trade executed: {} {} at ${:.6}",
                    trade.amount, trade.token_mint, trade.price);
            }
            
            WebSocketMessage::BalanceUpdate(balance) => {
                println!("Portfolio value: ${:.2}", balance.total_value_usd);
                for token in &balance.token_balances {
                    println!("  {}: {} (${:.2})", 
                        token.symbol, token.amount, token.value_usd);
                }
            }
            
            WebSocketMessage::Error { code, message } => {
                eprintln!("WebSocket error {}: {}", code, message);
            }
            
            _ => {}
        }
    }
    
    async fn on_connected(&self, session_id: String) {
        println!("✅ WebSocket connected! Session: {}", session_id);
    }
    
    async fn on_disconnected(&self, reason: String) {
        println!("❌ WebSocket disconnected: {}", reason);
        // Implement custom reconnection logic here if needed
    }
    
    async fn on_error(&self, error: String) {
        eprintln!("⚠️ WebSocket error: {}", error);
    }
}
}

Subscription Types

The WebSocket client supports various data feed subscriptions:

New Token Listings

Subscribe to newly launched tokens on the platform:

#![allow(unused)]
fn main() {
// Subscribe to all new token pairs
ws_client.subscribe_new_tokens().await?;
}

Token Price Updates

Monitor real-time price changes for specific tokens:

#![allow(unused)]
fn main() {
// Subscribe to price updates for a specific token
let bonk_address = "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263";
ws_client.subscribe_token_price(bonk_address).await?;

// Subscribe to multiple tokens
let tokens = vec![
    "So11111111111111111111111111111111111111112", // SOL
    "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", // USDC
    "DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263", // BONK
];

for token in tokens {
    ws_client.subscribe_token_price(token).await?;
}
}

Wallet Transaction Monitoring

Track transactions for specific wallet addresses:

#![allow(unused)]

                last_updated: std::time::Instant::now(),
            });
        
        price_data.current_price = price;
        price_data.high_24h = price_data.high_24h.max(price);
        price_data.low_24h = price_data.low_24h.min(price);

        // Check price alerts
        for alert in &self.alerts {
            if alert.token == symbol {

                    }
                    AlertCondition::Below if price < alert.target_price => {
                        println!("🔔 ALERT: {} is below ${:.6}!", symbol, alert.target_price);
                    }
                    _ => {}
                }
            }
        }
    }
}
}

Connection Management and Reconnection Logic

Automatic Reconnection

The WebSocket client includes built-in reconnection logic:

#![allow(unused)]
fn main() {
// Enable automatic reconnection (enabled by default)
ws_client.set_auto_reconnect(true);

// The client will automatically:
// 1. Refresh authentication tokens every 10 minutes
// 2. Reconnect if the connection is lost
// 3. Re-subscribe to all previous subscriptions
}

Manual Reconnection

#![allow(unused)]
fn main() {
// Check connection status
if !ws_client.is_connected().await {
    println!("Connection lost, reconnecting...");
    
    match ws_client.reconnect().await {
        Ok(()) => {
            println!("Reconnected successfully");
            
            // Re-subscribe to feeds if needed
            ws_client.subscribe_new_tokens().await?;
        }
        Err(e) => {
            eprintln!("Reconnection failed: {}", e);
        }
    }
}
}

Connection Health Monitoring

#![allow(unused)]
fn main() {
use tokio::time::{interval, Duration};

async fn monitor_connection(ws_client: &mut WebSocketClient) {
    let mut health_check = interval(Duration::from_secs(30));
    
    loop {
        health_check.tick().await;
        
        if !ws_client.is_connected().await {
            println!("⚠️ Connection lost, attempting reconnection...");
            
            match ws_client.reconnect().await {
                Ok(()) => {
                    println!("✅ Reconnection successful");
                }
                Err(e) => {
                    eprintln!("❌ Reconnection failed: {}", e);
                    // Implement exponential backoff or other retry logic
                }
            }
        }
        
        // Display current subscriptions
        let subs = ws_client.get_subscriptions().await;
        println!("Active subscriptions: {:?}", subs);
    }
}
}

Token Price WebSocket

For dedicated price monitoring, use the token price WebSocket:

#![allow(unused)]
fn main() {
// Connect to the specialized token price stream
let mut price_ws = WebSocketClient::new(handler)?;
price_ws.connect_token_price().await?;

// This uses socket8.axiom.trade specifically for price data
}

Error Handling

WebSocket Error Types

#![allow(unused)]
fn main() {
pub enum WebSocketError {
    AuthError(AuthError),           // Authentication failure
    ConnectionError(String),        // Connection issues
    NotConnected,                  // Not connected when operation attempted
    SendError(String),             // Failed to send message
    ReceiveError(String),          // Failed to receive message
    SerializationError(String),    // JSON parsing errors
    WebSocketError(tokio_tungstenite::tungstenite::Error), // Low-level WebSocket errors
    HttpError(http::Error),        // HTTP upgrade errors
}
}

Robust Error Handling Example

#![allow(unused)]
fn main() {
async fn robust_websocket_connection() -> Result<(), Box<dyn std::error::Error>> {
    let handler = Arc::new(MyMessageHandler::new());
    let mut ws_client = WebSocketClient::new(handler)?;
    
    let mut retry_count = 0;
    const MAX_RETRIES: u32 = 5;
    
    loop {
        match ws_client.connect().await {
            Ok(()) => {
                println!("✅ Connected successfully");
                break;
            }
            Err(e) => {
                retry_count += 1;
                eprintln!("❌ Connection failed (attempt {}): {}", retry_count, e);
                
                if retry_count >= MAX_RETRIES {
                    return Err(format!("Failed to connect after {} attempts", MAX_RETRIES).into());
                }
                
                // Exponential backoff
                let delay = Duration::from_secs(2_u64.pow(retry_count));
                println!("⏳ Retrying in {:?}...", delay);
                tokio::time::sleep(delay).await;
            }
        }
    }
    
    // Subscribe with error handling
    if let Err(e) = ws_client.subscribe_new_tokens().await {
        eprintln!("⚠️ Failed to subscribe to new tokens: {}", e);
    }
    
    Ok(())
}
}

Best Practices

1. Use Arc for Shared Message Handlers

#![allow(unused)]
fn main() {
// Good: Use Arc for shared ownership
let handler = Arc::new(MyMessageHandler::new());
let mut ws_client = WebSocketClient::new(handler.clone())?;

// The handler can be safely shared across async tasks
let handler_clone = handler.clone();
tokio::spawn(async move {
    // Use handler_clone in another task
});
}

2. Implement Connection Pooling for Multiple Streams

#![allow(unused)]
fn main() {
struct WebSocketManager {
    connections: HashMap<String, WebSocketClient>,
    handler: Arc<dyn MessageHandler>,
}

impl WebSocketManager {
    async fn create_connection(&mut self, name: &str, region: Region) -> Result<(), WebSocketError> {
        let mut client = WebSocketClient::with_region(self.handler.clone(), region)?;
        client.connect().await?;
        self.connections.insert(name.to_string(), client);
        Ok(())
    }
    
    async fn subscribe_to_token(&mut self, connection_name: &str, token: &str) -> Result<(), WebSocketError> {
        if let Some(client) = self.connections.get_mut(connection_name) {
            client.subscribe_token_price(token).await
        } else {
            Err(WebSocketError::NotConnected)
        }
    }
}
}

3. Rate Limiting Subscriptions

#![allow(unused)]
fn main() {
use tokio::time::{interval, Duration};

async fn subscribe_with_rate_limit(
    ws_client: &mut WebSocketClient,
    tokens: Vec<&str>
) -> Result<(), WebSocketError> {
    let mut rate_limiter = interval(Duration::from_millis(100));
    
    for token in tokens {
        rate_limiter.tick().await;
        
        match ws_client.subscribe_token_price(token).await {
            Ok(()) => {
                println!("✅ Subscribed to {}", token);
            }
            Err(e) => {
                eprintln!("❌ Failed to subscribe to {}: {}", token, e);
            }
        }
    }
    
    Ok(())
}
}

4. Graceful Shutdown

use tokio::signal;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let handler = Arc::new(MyMessageHandler::new());
    let mut ws_client = WebSocketClient::new(handler)?;
    
    ws_client.connect().await?;
    ws_client.subscribe_new_tokens().await?;
    
    // Set up graceful shutdown
    tokio::select! {
        _ = signal::ctrl_c() => {
            println!("🛑 Shutdown signal received");
        }
        _ = monitor_websocket(&mut ws_client) => {
            println!("WebSocket monitoring ended");
        }
    }
    
    // Graceful disconnect
    println!("Disconnecting...");
    ws_client.disconnect().await;
    println!("✅ Disconnected gracefully");
    
    Ok(())
}

async fn monitor_websocket(ws_client: &mut WebSocketClient) {
    loop {
        if !ws_client.is_connected().await {
            if let Err(e) = ws_client.reconnect().await {
                eprintln!("Failed to reconnect: {}", e);
                break;
            }
        }
        
        tokio::time::sleep(Duration::from_secs(5)).await;
    }
}

This module supports multiple notification types, delivery methods, and configuration options to keep users informed of important events.

Overview

The notifications API allows users to:

  • Create and manage price alerts for specific tokens
  • Monitor wallet activity with customizable filters
  • Receive system notifications and announcements
  • Configure email notifications with custom templates
  • Set up notification preferences and delivery methods
  • Track notification history and engagement metrics

NotificationsClient

The NotificationsClient provides access to all notification functionality:

#![allow(unused)]
fn main() {
use axiomtrade_rs::api::notifications::NotificationsClient;

let mut client = NotificationsClient::new()?;
}

Price Alerts

Price alerts notify users when token prices reach specified thresholds or meet certain conditions.

Creating Price Alerts

#![allow(unused)]
fn main() {
use axiomtrade_rs::models::notifications::*;

let alert_request = PriceAlertRequest {
    token_address: "So11111111111111111111111111111111111111112".to_string(),
    alert_type: PriceAlertType::AbsolutePrice,
    target_price: 150.0,
    comparison: PriceComparison::Above,
    notification_methods: vec![
        NotificationMethod::Email,
        NotificationMethod::InApp,
    ],
    is_one_time: true,
    expires_at: Some(chrono::Utc::now() + chrono::Duration::days(30)),
};

let alert_id = client.create_price_alert(alert_request).await?;
println!("Created price alert: {}", alert_id);
}

Price Alert Types

  • AbsolutePrice: Alert when token reaches a specific price
  • PercentageChange: Alert on percentage price movement
  • VolumeThreshold: Alert when trading volume exceeds threshold
  • MarketCapThreshold: Alert based on market capitalization changes

Price Comparison Options

  • Above: Trigger when price goes above target
  • Below: Trigger when price goes below target
  • Equal: Trigger when price equals target (within tolerance)
  • PercentageIncrease: Trigger on percentage increase
  • PercentageDecrease: Trigger on percentage decrease

Managing Price Alerts

#![allow(unused)]
fn main() {
// Delete a price alert
let success = client.delete_price_alert("alert_id").await?;

// List all price alerts (via get_notifications)
let notifications = client.get_notifications().await?;
let price_alerts: Vec<_> = notifications
    .into_iter()
    .filter(|n| n.notification_type == NotificationType::PriceAlert)
    .collect();
}

Wallet Activity Alerts

Monitor specific wallet addresses for trading activity and transactions.

Creating Wallet Alerts

#![allow(unused)]
fn main() {
let wallet_alert = WalletAlertRequest {
    wallet_address: "5Q544fKrFoe6tsEbD7S8EmxGTJYAKtTVhAW5Q5pge4j1".to_string(),
    activity_types: vec![
        WalletActivityType::Buy,
        WalletActivityType::Sell,
        WalletActivityType::LargeTransaction,
    ],
    min_transaction_value: Some(1000.0), // Minimum $1000 transactions
    token_filters: vec![
        "So11111111111111111111111111111111111111112".to_string(), // SOL
    ],
    notification_methods: vec![
        NotificationMethod::Email,
        NotificationMethod::InApp,
    ],
    is_active: true,
};

let alert_id = client.create_wallet_alert(wallet_alert).await?;
}

Wallet Activity Types

  • Buy: Token purchase transactions
  • Sell: Token sale transactions
  • Swap: Token swap operations
  • Transfer: Token transfer events
  • LargeTransaction: Transactions above specified value
  • NewToken: First interaction with new tokens
  • AllActivity: Monitor all wallet activity

System Notifications

System notifications provide information about platform status, maintenance, and important updates.

Retrieving Notifications

#![allow(unused)]
fn main() {
// Get user notifications
let notifications = client.get_notifications().await?;
for notification in notifications {
    println!("{}: {}", notification.title, notification.message);
    if !notification.is_read {
        println!("  Priority: {:?}", notification.priority);
        println!("  Created: {}", notification.created_at);
    }
}

// Get system announcements
let announcements = client.get_announcements().await?;
for announcement in announcements {
    println!("Announcement: {}", announcement.title);
    println!("Type: {:?}", announcement.announcement_type);
    println!("Target: {:?}", announcement.target_audience);
    
    if announcement.action_required {
        println!("Action required: {}", announcement.action_url.unwrap_or_default());
    }
}
}

Notification Types

  • PriceAlert: Price-based alerts
  • WalletActivity: Wallet monitoring alerts
  • TradeExecution: Trade confirmation notifications
  • SystemUpdate: Platform updates and changes
  • SecurityAlert: Security-related notifications
  • MarketNews: Market information and news
  • SocialMention: Social media mentions and sentiment

Notification Priorities

  • Low: Informational messages
  • Medium: Standard notifications
  • High: Important alerts requiring attention
  • Critical: Urgent notifications requiring immediate action

Managing Notifications

#![allow(unused)]
fn main() {
// Mark specific notification as read
let success = client.mark_notification_read("notification_id").await?;

// Mark all notifications as read
let success = client.mark_all_notifications_read().await?;
}

Email Notifications

Configure email delivery for notifications with customizable templates and scheduling.

Email Notification Settings

#![allow(unused)]
fn main() {
// Get current email settings
let settings = client.get_notification_settings().await?;
println!("Email notifications enabled: {}", settings.email_notifications);

// Update email settings
let mut updated_settings = settings;
updated_settings.email_notifications = true;
updated_settings.preferred_methods = vec![
    NotificationMethod::Email,
    NotificationMethod::InApp,
];

let success = client.update_notification_settings(updated_settings).await?;
}

Notification Delivery Methods

  • InApp: Display within the application interface
  • Email: Send via email to configured address
  • Push: Push notifications to mobile devices
  • Webhook: HTTP POST to configured webhook URL
  • Telegram: Send to Telegram bot/channel
  • Discord: Send to Discord webhook

Notification Configuration

Notification Settings Structure

#![allow(unused)]
fn main() {
pub struct NotificationSettings {
    pub email_notifications: bool,
    pub push_notifications: bool,
    pub in_app_notifications: bool,
    pub price_alerts_enabled: bool,
    pub wallet_alerts_enabled: bool,
    pub social_mentions_enabled: bool,
    pub market_news_enabled: bool,
    pub trade_confirmations_enabled: bool,
    pub security_alerts_enabled: bool,
    pub quiet_hours: Option<QuietHours>,
    pub preferred_methods: Vec<NotificationMethod>,
    pub frequency_limits: FrequencyLimits,
}
}

Quiet Hours Configuration

Set times when notifications should be suppressed:

#![allow(unused)]
fn main() {
let quiet_hours = QuietHours {
    enabled: true,
    start_time: "22:00".to_string(), // 10 PM
    end_time: "07:00".to_string(),   // 7 AM
    timezone: "UTC".to_string(),
    days: vec![
        "monday".to_string(),
        "tuesday".to_string(),
        "wednesday".to_string(),
        "thursday".to_string(),
        "friday".to_string(),
    ],
};
}

Frequency Limits

Control notification frequency to prevent spam:

#![allow(unused)]
fn main() {
let frequency_limits = FrequencyLimits {
    max_price_alerts_per_hour: 10,
    max_wallet_alerts_per_hour: 20,
    max_social_alerts_per_hour: 5,
    batch_similar_notifications: true,
    batch_delay_minutes: 15,
};
}

Alert Management

Best Practices

  1. Set Appropriate Thresholds: Avoid too many low-value alerts
  2. Use Expiration Dates: Set expiration for temporary alerts
  3. Configure Quiet Hours: Respect user sleep schedules
  4. Batch Similar Notifications: Reduce notification fatigue
  5. Monitor Delivery Success: Track notification effectiveness

Performance Considerations

  • Rate Limiting: Respect API rate limits when creating multiple alerts
  • Batch Operations: Use batch endpoints for multiple alerts
  • Efficient Filtering: Use appropriate filters to reduce unnecessary notifications
  • Cleanup: Remove expired or unnecessary alerts regularly

Error Handling

#![allow(unused)]
fn main() {
use axiomtrade_rs::errors::AxiomError;

match client.create_price_alert(alert_request).await {
    Ok(alert_id) => {
        println!("Alert created successfully: {}", alert_id);
    }
    Err(AxiomError::Api { message }) => {
        eprintln!("API error creating alert: {}", message);
    }
    Err(AxiomError::Network(e)) => {
        eprintln!("Network error: {}", e);
    }
    Err(e) => {
        eprintln!("Unexpected error: {}", e);
    }
}
}

Security Considerations

  • Webhook Security: Use HTTPS endpoints and validate webhook signatures
  • Email Privacy: Be cautious with sensitive information in email notifications
  • Rate Limiting: Implement client-side rate limiting to prevent abuse
  • Data Validation: Validate all notification data before processing
  • Access Control: Ensure users can only access their own notifications

The notifications API provides a comprehensive system for keeping users informed about their trading activities and platform updates. Proper configuration and management of notifications can significantly enhance the user experience while maintaining security and preventing notification fatigue.

Turnkey Integration

The Turnkey integration provides enterprise-grade hardware wallet management with P256 cryptographic operations for secure trading on Axiom Trade. This integration handles key management, authentication, and secure signing through Turnkey's infrastructure.

Overview

Turnkey is a secure wallet infrastructure that provides:

  • Hardware-level key security
  • P256 elliptic curve cryptography
  • API key management
  • Session-based authentication
  • Enterprise-grade access controls

Turnkey Setup

Prerequisites

Before using the Turnkey integration, ensure you have:

  1. Turnkey Organization Account: A registered organization on Turnkey
  2. User Credentials: Valid user account within the organization
  3. Environment Variables: Properly configured authentication details

Initial Configuration

The Turnkey client requires minimal setup:

#![allow(unused)]
fn main() {
use axiomtrade_rs::api::turnkey::TurnkeyClient;

// Create a new Turnkey client
let mut turnkey_client = TurnkeyClient::new();

// Set credentials for authenticated operations
turnkey_client.set_credentials(
    organization_id,
    user_id,
    password  // Raw password for P256 key derivation
);
}

Session Management

Turnkey sessions are automatically managed through the authentication flow:

#![allow(unused)]
fn main() {
// Load existing session from file
let session_content = std::fs::read_to_string(".axiom_turnkey_session.json")?;
let session: AuthSession = serde_json::from_str(&session_content)?;

if let Some(turnkey_session) = session.turnkey_session {
    // Use existing session
    println!("Organization: {}", turnkey_session.organization_id);
    println!("User: {}", turnkey_session.username);
}
}

Hardware Wallet Authentication

Authentication Flow

The Turnkey authentication process involves several steps:

  1. Identity Verification: Confirm user identity with the organization
  2. API Key Retrieval: Fetch available API keys for operations
  3. Session Creation: Establish secure session for trading operations

Step 1: Identity Verification

#![allow(unused)]
fn main() {
// Verify user identity
let whoami = turnkey_client.whoami(
    &organization_id,
    &client_secret
).await?;

println!("Authenticated as: {}", whoami.username);
println!("Organization: {}", whoami.organization_name);
}

Step 2: API Key Management

#![allow(unused)]
fn main() {
// Retrieve API keys for the user
let api_keys = turnkey_client.get_api_keys(
    &user_id,
    &organization_id,
    &client_secret
).await?;

println!("Available API keys: {}", api_keys.api_keys.len());

for key in &api_keys.api_keys {
    println!("Key: {} (Type: {})", key.api_key_name, key.credential.credential_type);
}
}

Step 3: Session Creation

#![allow(unused)]
fn main() {
// Create read/write session for trading operations
let success = turnkey_client.create_read_write_session(
    organization_id,
    user_id,
    target_public_key,
    "trading-session"
).await?;

if success {
    println!("Trading session created successfully");
}
}

Session Validation

The client provides methods to validate and monitor session health:

#![allow(unused)]
fn main() {
// Check service health
let is_healthy = turnkey_client.health_check().await?;

// Parse and validate session
let parsed_session = turnkey_client.parse_session(
    &whoami,
    &api_keys,
    &client_secret
);

// Get session summary
let summary = turnkey_client.session_summary(&parsed_session);
println!("Session status: {}", summary);
}

P256 Cryptography

Key Generation

The integration uses P256 elliptic curve cryptography for secure operations:

#![allow(unused)]
fn main() {
use axiomtrade_rs::utils::p256_crypto;

// Generate P256 keypair from password
let keypair = p256_crypto::generate_p256_keypair_from_password(
    password,
    None  // Random salt, or provide specific salt
)?;

println!("Public key: {}", keypair.public_key);
println!("Private key length: {}", keypair.private_key.len());
}

Deterministic Key Recreation

Keys can be recreated deterministically using the client secret:

#![allow(unused)]
fn main() {
// Recreate keypair from stored client secret
let keypair = p256_crypto::recreate_keypair_from_client_secret(
    password,
    client_secret
)?;

// Keys will be identical to original generation
}

Key Security Features

  • PBKDF2 with SHA256: 600,000 iterations for key derivation
  • P256 Curve: NIST P-256 elliptic curve (secp256r1)
  • Compressed Public Keys: Space-efficient key representation
  • Secure Salt Generation: Cryptographically secure random salts

Secure Signing

Message Signing

The client handles request signing automatically:

#![allow(unused)]
fn main() {
// Sign arbitrary message
let message = b"transaction_data";
let signature = p256_crypto::sign_message(message, &private_key)?;

println!("Signature length: {} bytes", signature.len());
println!("Format: DER encoded");
}

WebAuthn Compatible Signing

For WebAuthn and browser-compatible operations:

#![allow(unused)]
fn main() {
// Generate WebAuthn-compatible signature (raw r,s format)
let webauthn_signature = p256_crypto::sign_message_webauthn(
    message,
    &private_key
)?;

// Signature is exactly 64 bytes (32-byte r + 32-byte s)
assert_eq!(webauthn_signature.len(), 64);
}

Signature Verification

#![allow(unused)]
fn main() {
// Verify signature authenticity
let is_valid = p256_crypto::verify_signature(
    message,
    &signature,
    &public_key
)?;

if is_valid {
    println!("Signature verified successfully");
}
}

Request Authentication

Turnkey requests are automatically signed with the X-Stamp header:

#![allow(unused)]
fn main() {
// Internal signing process (handled automatically)
let signature = self.sign_request(payload_json.as_bytes(), client_secret)?;

// Headers include authentication stamp
.header("X-Stamp", signature)
.header("x-client-version", "@turnkey/sdk-server@1.7.3")
}

API Methods

Core Operations

Identity and Authentication

#![allow(unused)]
fn main() {
// Get current user identity
let whoami: TurnkeyWhoAmI = turnkey_client.whoami(
    organization_id,
    client_secret
).await?;

// Fields available:
// - organization_id: String
// - organization_name: String  
// - user_id: String
// - username: String
}

API Key Management

#![allow(unused)]
fn main() {
// Retrieve all API keys for user
let api_keys: GetApiKeysResponse = turnkey_client.get_api_keys(
    user_id,
    organization_id,
    client_secret
).await?;

// Access key information
for key in api_keys.api_keys {
    println!("Key ID: {}", key.api_key_id);
    println!("Name: {}", key.api_key_name);
    println!("Public Key: {}", key.credential.public_key);
    println!("Type: {}", key.credential.credential_type);
}
}

Session Management

#![allow(unused)]
fn main() {
// Create secure session for operations
let success: bool = turnkey_client.create_read_write_session(
    organization_id,
    user_id,
    target_public_key,
    api_key_name
).await?;

// Sessions expire after 30 days by default
}

Utility Methods

Session Information

#![allow(unused)]
fn main() {
// Get specific API key by type
let session_key = turnkey_client.get_session_key(
    &session,
    "CREDENTIAL_TYPE_READ_WRITE_SESSION_KEY_P256"
);

// Generate human-readable session summary
let summary = turnkey_client.session_summary(&session);
println!("{}", summary);
// Output: "Turnkey Session - User: alice, Keys: 2/3 active, Age: 45m, Expires: 120m"
}

Health Monitoring

#![allow(unused)]
fn main() {
// Check Turnkey service availability
let is_healthy: bool = turnkey_client.health_check().await?;

if !is_healthy {
    println!("Turnkey service may be experiencing issues");
}
}

Error Handling

The integration provides comprehensive error handling:

#![allow(unused)]
fn main() {
match turnkey_client.whoami(org_id, client_secret).await {
    Ok(whoami) => {
        println!("Authentication successful: {}", whoami.username);
    }
    Err(AxiomError::Api { message, .. }) if message.contains("PUBLIC_KEY_NOT_FOUND") => {
        println!("Public key not registered with Turnkey organization");
    }
    Err(AxiomError::Api { message, .. }) if message.contains("unauthorized") => {
        println!("Invalid authentication credentials");
    }
    Err(AxiomError::Network { .. }) => {
        println!("Network connectivity issue");
    }
    Err(e) => {
        println!("Unexpected error: {}", e);
    }
}
}

Integration with Axiom Trade

Session Storage

Turnkey sessions are integrated with the main authentication system:

#![allow(unused)]
fn main() {
// Sessions are stored in .axiom_turnkey_session.json
let auth_session = AuthSession {
    tokens: auth_tokens,
    cookies: auth_cookies,
    turnkey_session: Some(turnkey_session),
    user_info: user_info,
    session_metadata: metadata,
};
}

Automatic Session Management

The client automatically handles:

  • Session expiration checking
  • Key rotation
  • Error recovery
  • Health monitoring

Trading Integration

Turnkey sessions enable secure trading operations:

#![allow(unused)]
fn main() {
// Session provides cryptographic signing for trades
if let Some(turnkey) = &session.turnkey_session {
    // Use Turnkey session for secure trade signing
    let trade_signature = sign_trade_request(&trade_data, &turnkey.client_secret)?;
}
}

Security Considerations

Key Security

  • Hardware-backed: Keys are protected by Turnkey's hardware infrastructure
  • Never exposed: Private keys never leave the secure environment
  • P256 cryptography: Industry-standard elliptic curve cryptography
  • Secure derivation: PBKDF2 with high iteration count

Session Security

  • Limited lifetime: Sessions expire automatically (30 days default)
  • Activity tracking: All operations are logged and monitored
  • Secure transmission: All communications use TLS encryption
  • Authentication required: Every request requires cryptographic signature

Best Practices

  1. Store passwords securely: Use OS keychain or secure storage
  2. Monitor session health: Regular health checks and renewal
  3. Handle errors gracefully: Implement proper error recovery
  4. Rotate keys regularly: Follow organizational key rotation policies
  5. Validate responses: Always verify API responses and signatures

Troubleshooting

Common Issues

Authentication Failures

#![allow(unused)]
fn main() {
// Handle common authentication issues
fn handle_auth_failure(error: AxiomError) -> Result<()> {
    match error {
        AxiomError::Api { message, .. } if message.contains("PUBLIC_KEY_NOT_FOUND") => {
            println!("Solution: Ensure public key is registered in Turnkey organization");
        }
        AxiomError::Api { message, .. } if message.contains("unauthorized") => {
            println!("Solution: Check password and client secret are correct");
        }
        AxiomError::Network { .. } => {
            println!("Solution: Check internet connection");
        }
        _ => {
            println!("Unknown error: {}", error);
        }
    }
    Ok(())
}
}

Session Issues

  • Expired sessions: Re-authenticate to refresh session
  • Invalid keys: Verify key registration in Turnkey organization
  • Network issues: Check connectivity and retry with backoff

Key Generation Problems

  • Invalid salt: Ensure client secret is properly base64 encoded
  • Wrong password: Verify password matches original key generation
  • Curve validation: Ensure derived key is valid for P256 curve

Debug Information

Enable detailed logging for troubleshooting:

#![allow(unused)]
fn main() {
// Get comprehensive session information
let summary = turnkey_client.session_summary(&session);
println!("Debug: {}", summary);

// Check individual key status
for key in &session.api_keys {
    if let Some(expires_at) = key.expires_at {
        let remaining = expires_at - chrono::Utc::now();
        println!("Key {} expires in {} minutes", key.api_key_name, remaining.num_minutes());
    }
}
}

This integration provides enterprise-grade security for cryptocurrency trading operations while maintaining ease of use and robust error handling.

Authentication Examples

This section provides comprehensive examples of authentication with the Axiom Trade API. The examples demonstrate different authentication methods, session management, and OTP handling.

Overview

The authentication system in axiomtrade-rs supports multiple authentication methods:

  • Basic Login: Email/password authentication with token management
  • OTP Verification: Automatic OTP fetching from inbox.lv email service
  • Session Management: Persistent sessions with token refresh capabilities
  • Cookie Authentication: Web-based authentication for browser integrations

Prerequisites

Before running any authentication examples, ensure you have:

  1. Environment Setup: Configure your .env file with required credentials
  2. Dependencies: All required crates are installed via cargo build
  3. Optional OTP Setup: Configure inbox.lv for automatic OTP retrieval

Required Environment Variables

# Basic authentication (required)
AXIOM_EMAIL=your_email@example.com
AXIOM_PASSWORD=your_password

# Optional OTP automation (recommended)
INBOX_LV_EMAIL=your_username@inbox.lv
INBOX_LV_PASSWORD=your_imap_password

cargo run --example otp_verification

# Without automatic OTP (manual entry required)
cargo run --example otp_verification

Features Demonstrated

  • Automatic OTP Retrieval: Fetching OTP codes from inbox.lv email service
  • Manual OTP Fallback: User input for OTP when automation is not configured
  • OTP Configuration Detection: Checking if automatic OTP is properly set up
  • Email Integration: IMAP integration for OTP retrieval
  • Seamless Authentication: Handling OTP verification transparently

OTP Setup Requirements

To enable automatic OTP retrieval:

  1. Create inbox.lv account at https://www.inbox.lv/
  2. Enable IMAP access:
    • Go to Settings → "Outlook, email programs"
    • Click "Enable" button
    • Wait 15 minutes for activation
  3. Get IMAP password (different from web login password)
  4. Configure email forwarding from Axiom Trade to your inbox.lv address
  5. Set environment variables: 
    INBOX_LV_EMAIL=your_username@inbox.lv
INBOX_LV_PASSWORD=your_special_imap_password

Expected Output

Common Issues and Troubleshooting

Authentication Failures

Problem: Login fails with invalid credentials

Login failed: Authentication failed: Invalid email or password

Solutions:

  1. Verify credentials in .env file
  2. Check for typos in email/password
  3. Ensure account is not locked or suspended

OTP Issues

Problem: OTP verification fails

Login failed: OTP verification failed

Solutions:

  1. Configure inbox.lv automatic OTP retrieval
  2. Check email forwarding is set up correctly
  3. Verify IMAP credentials are correct
  4. Check for email delivery delays

Token Issues

Problem: Token persistence fails

Warning: Failed to save tokens: Permission denied

Solutions:

  1. Check file permissions in working directory
  2. Ensure disk space is available
  3. Run with appropriate user permissions

Network Issues

Problem: Connection timeouts

Login failed: Network error: Connection timeout

Solutions:

  1. Check internet connectivity
  2. Verify firewall settings
  3. Try again with network retry logic

Security Considerations

Token Storage

  • Never commit tokens to version control
  • Use secure storage mechanisms (OS keychain when possible)
  • Implement token rotation for long-running applications
  • Clear tokens on logout to prevent misuse

OTP Security

  • Use dedicated email account for OTP automation
  • Enable two-factor authentication on email account
  • Monitor for unauthorized access to email account
  • Consider rate limiting for OTP requests
  • Always use HTTPS in production
  • Set appropriate cookie flags (HttpOnly, Secure, SameSite)
  • Implement CSRF protection for web applications
  • Use short expiry times for sensitive operations

Environment Variables

  • Never commit .env files to version control
  • Use environment-specific configurations
  • Implement secret rotation for production systems
  • Monitor for credential leaks in logs and error messages

  • Token holding details with market values

Example Usage

#![allow(unused)]
fn main() {
use axiomtrade_rs::api::portfolio::PortfolioClient;
use axiomtrade_rs::auth::AuthClient;

// Authenticate and create portfolio client
let mut auth_client = AuthClient::new()?;
auth_client.login(&email, &password, None).await?;
let mut portfolio_client = PortfolioClient::new()?;

// Define wallets to analyze
let wallet_addresses = vec![
    "DYw8jCTfwHNRJhhmFcbXvVDTqWMEVFBX6ZKUmG5CNSKK".to_string(),
    "5FHwkrdxntdK24hgQU8qgBjn35Y1zwhz1GZwCkP2UJnM".to_string(),
];

// Get comprehensive portfolio summary
let portfolio = portfolio_client.get_portfolio_summary(&wallet_addresses).await?;

// Access portfolio data
println!("Total Value: {:.4} SOL", portfolio.balance_stats.total_value_sol);
println!("Available Balance: {:.4} SOL", portfolio.balance_stats.available_balance_sol);
println!("Unrealized PnL: {:.4} SOL", portfolio.balance_stats.unrealized_pnl_sol);
}

Trading Examples

This section provides comprehensive examples for using the Axiom Trade API trading functionality, including simple trades, error handling patterns, and advanced trading strategies.

Simple Trade Example

The simple_trade.rs example demonstrates the fundamental trading operations available through the Axiom Trade API. This example serves as a starting point for understanding the trading workflow and best practices.

Overview

The simple trade example showcases:

  • Authentication setup for trading
  • Buy and sell operations simulation
  • Price quote retrieval
  • Parameter validation
  • Error handling patterns
  • Security best practices

Example Walkthrough

use axiomtrade_rs::{AuthClient, Result, AxiomError};
use axiomtrade_rs::api::trading::TradingClient;
use std::env;

#[tokio::main]
async fn main() -> Result<()> {
    // Load credentials and authenticate
    dotenvy::dotenv().ok();
    let mut trading_client = authenticate().await?;

    // Trading parameters
    let token_mint = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"; // USDC
    let amount_sol = 0.001; // Small demonstration amount
    
    // Execute buy operation
    simulate_buy_trade(&mut trading_client, token_mint, amount_sol).await?;
    
    // Execute sell operation  
    let amount_tokens = 1.0; // 1 USDC
    simulate_sell_trade(&mut trading_client, token_mint, amount_tokens).await?;
    
    Ok(())
}

Authentication Setup

The example begins with proper authentication using environment variables:

#![allow(unused)]
fn main() {
async fn authenticate() -> Result<TradingClient> {
    let email = env::var("AXIOM_EMAIL")
        .expect("AXIOM_EMAIL must be set in .env file");
    let password = env::var("AXIOM_PASSWORD")
        .expect("AXIOM_PASSWORD must be set in .env file");

    let mut auth_client = AuthClient::new()?;
    
    match auth_client.login_full(&email, &password, None).await {
        Ok(login_result) => {
            println!("Authentication successful!");
            println!("Access token obtained: {}", &login_result.tokens.access_token[..20]);
        }
        Err(e) => {
            return Err(AxiomError::Auth(e));
        }
    }

    TradingClient::new().map_err(|e| AxiomError::Api {
        message: format!("Failed to create trading client: {}", e),
    })
}
}

Trade Parameters

Essential Parameters

When executing trades, several key parameters must be configured:

ParameterTypeDescriptionExample
token_mint&strTarget token mint address"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
amountf64Trade amount in base units0.001 (SOL) or 1.0 (tokens)
slippageOption<f64>Maximum acceptable slippage percentageSome(1.0) (1%)
priority_feeOption<f64>Additional priority fee in SOLSome(0.00001)

Token Mint Addresses

Common token mint addresses used in examples:

#![allow(unused)]
fn main() {
// Native SOL
const SOL_MINT: &str = "So11111111111111111111111111111111111111112";

// USDC
const USDC_MINT: &str = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v";

// USDT  
const USDT_MINT: &str = "Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB";
}

Slippage Configuration

Slippage tolerance should be set based on token liquidity and market conditions:

#![allow(unused)]
fn main() {
let slippage_scenarios = vec![0.1, 0.5, 1.0, 2.0, 5.0];

for slippage in slippage_scenarios {
    let estimated_impact = calculate_slippage_impact(amount_sol, slippage);
    println!("{}% slippage tolerance - Max cost: {} SOL", 
        slippage, estimated_impact);
}
}

Recommended slippage settings:

  • Liquid tokens (SOL, USDC, USDT): 0.1% - 0.5%
  • Mid-cap tokens: 0.5% - 1.0%
  • Low liquidity tokens: 1.0% - 5.0%
  • Volatile markets: 2.0% - 5.0%

Error Handling

The trading system implements comprehensive error handling patterns to ensure robust operation.

Parameter Validation

All trading parameters undergo validation before execution:

#![allow(unused)]
fn main() {
fn validate_amount(amount: f64, unit: &str) -> Result<()> {
    if amount <= 0.0 {
        return Err(AxiomError::Api {
            message: format!("Amount must be greater than 0, got {} {}", amount, unit),
        });
    }
    
    if amount.is_nan() || amount.is_infinite() {
        return Err(AxiomError::Api {
            message: format!("Invalid amount: {} {}", amount, unit),
        });
    }
    
    Ok(())
}

fn validate_token_mint(mint: &str) -> Result<()> {
    if mint.is_empty() {
        return Err(AxiomError::Api {
            message: "Token mint cannot be empty".to_string(),
        });
    }
    
    if mint.len() < 32 || mint.len() > 44 {
        return Err(AxiomError::Api {
            message: format!("Invalid mint address length: {}", mint),
        });
    }
    
    if !mint.chars().all(|c| c.is_ascii_alphanumeric()) {
        return Err(AxiomError::Api {
            message: format!("Invalid characters in mint address: {}", mint),
        });
    }
    
    Ok(())
}
}

Trading Limits Verification

Before executing trades, the system checks against trading limits:

#![allow(unused)]
fn main() {
match client.get_trading_limits().await {
    Ok(limits) => {
        if amount_sol < limits.min_sol_amount {
            return Err(AxiomError::Api {
                message: format!("Amount {} SOL is below minimum {}", 
                    amount_sol, limits.min_sol_amount)
            });
        }
        if amount_sol > limits.max_sol_amount {
            return Err(AxiomError::Api {
                message: format!("Amount {} SOL exceeds maximum {}", 
                    amount_sol, limits.max_sol_amount)
            });
        }
    }
    Err(_) => println!("Could not verify trading limits"),
}
}

Quote Retrieval Error Handling

Price quotes may fail due to network issues or market conditions:

#![allow(unused)]
fn main() {
match client.get_quote(sol_mint, token_mint, amount_sol, Some(1.0)).await {
    Ok(quote) => {
        println!("Current swap quote:");
        println!("  Input: {} SOL", quote.in_amount);
        println!("  Output: {} tokens", quote.out_amount);
        println!("  Price impact: {:.2}%", quote.price_impact);
        println!("  Fee: {} SOL", quote.fee);
    }
    Err(e) => {
        println!("Failed to get quote: {}", e);
        // Implement retry logic or fallback strategy
    }
}
}

Best Practices

1. Pre-Trade Validation

Always validate all parameters before executing trades:

#![allow(unused)]
fn main() {
// Validate trade parameters
validate_amount(amount_sol, "SOL")?;
validate_token_mint(token_mint)?;

// Check trading limits
let limits = client.get_trading_limits().await?;
ensure_within_limits(amount_sol, &limits)?;

// Get current quote for verification
let quote = client.get_quote(from_mint, to_mint, amount, slippage).await?;
verify_quote_acceptable(&quote)?;
}

2. Liquidity Assessment

Check token liquidity before executing large trades:

#![allow(unused)]
fn main() {
async fn assess_liquidity(client: &TradingClient, token_mint: &str) -> Result<bool> {
    match client.get_token_info(token_mint).await {
        Ok(info) => {
            println!("Token liquidity: {} SOL", info.liquidity_sol);
            println!("24h volume: {} SOL", info.volume_24h);
            
            // Consider liquid if > 100 SOL liquidity and > 10 SOL daily volume
            Ok(info.liquidity_sol > 100.0 && info.volume_24h > 10.0)
        }
        Err(_) => {
            println!("Could not assess liquidity for {}", token_mint);
            Ok(false)
        }
    }
}
}

3. Slippage Management

Implement dynamic slippage based on market conditions:

#![allow(unused)]
fn main() {
fn calculate_optimal_slippage(
    amount: f64, 
    liquidity: f64, 
    volatility: f64
) -> f64 {
    let base_slippage = 0.5; // 0.5% base
    let liquidity_factor = (amount / liquidity).min(0.1); // Cap at 10%
    let volatility_factor = volatility.min(0.05); // Cap at 5%
    
    base_slippage + liquidity_factor + volatility_factor
}
}

4. Transaction Monitoring

Monitor transaction status after execution:

#![allow(unused)]
fn main() {
async fn monitor_transaction(
    client: &TradingClient, 
    signature: &str
) -> Result<()> {
    let mut attempts = 0;
    let max_attempts = 30; // 30 seconds timeout
    
    while attempts < max_attempts {
        match client.get_transaction_status(signature).await {
            Ok(status) => {
                match status.as_str() {
                    "confirmed" => {
                        println!("Transaction confirmed: {}", signature);
                        return Ok(());
                    }
                    "failed" => {
                        return Err(AxiomError::Api {
                            message: format!("Transaction failed: {}", signature),
                        });
                    }
                    _ => {
                        println!("Transaction pending... ({})", status);
                    }
                }
            }
            Err(_) => {
                println!("Could not check transaction status");
            }
        }
        
        tokio::time::sleep(tokio::time::Duration::from_secs(1)).await;
        attempts += 1;
    }
    
    Err(AxiomError::Api {
        message: "Transaction timeout".to_string(),
    })
}
}

5. Portfolio Impact Analysis

Assess how trades will affect your portfolio:

#![allow(unused)]
fn main() {
async fn analyze_portfolio_impact(
    client: &TradingClient,
    token_mint: &str,
    amount: f64,
    is_buy: bool
) -> Result<()> {
    let portfolio = client.get_portfolio().await?;
    
    if is_buy {
        // Check if we have sufficient SOL
        if portfolio.sol_balance < amount {
            return Err(AxiomError::Api {
                message: format!("Insufficient SOL balance: {} < {}", 
                    portfolio.sol_balance, amount),
            });
        }
    } else {
        // Check if we have sufficient tokens to sell
        let token_balance = portfolio.get_token_balance(token_mint);
        if token_balance < amount {
            return Err(AxiomError::Api {
                message: format!("Insufficient token balance: {} < {}", 
                    token_balance, amount),
            });
        }
    }
    
    println!("Portfolio impact analysis passed");
    Ok(())
}
}

Advanced Trading Patterns

1. Dollar Cost Averaging (DCA)

Implement systematic buying over time:

#![allow(unused)]
fn main() {
pub struct DCAStrategy {
    token_mint: String,
    amount_per_trade: f64,
    interval_hours: u64,
    total_trades: usize,
    completed_trades: usize,
}

impl DCAStrategy {
    pub async fn execute_next_trade(
        &mut self, 
        client: &mut TradingClient
    ) -> Result<()> {
        if self.completed_trades >= self.total_trades {
            return Err(AxiomError::Api {
                message: "DCA strategy completed".to_string(),
            });
        }
        
        println!("Executing DCA trade {}/{}", 
            self.completed_trades + 1, self.total_trades);
            
        // Execute buy with current market conditions
        let result = client.buy_token(
            &self.token_mint,
            self.amount_per_trade,
            Some(1.0) // 1% slippage tolerance
        ).await?;

2. Grid Trading

Implement grid trading strategy:

#![allow(unused)]
fn main() {

3. Stop Loss Implementation

Implement automatic stop loss orders:

#![allow(unused)]
fn main() {
pub struct StopLossManager {
    positions: Vec<StopLossPosition>,

            let prices = self.get_multi_market_prices(client, token).await?;
            
            if prices.len() < 2 {
                continue;
            }
            
            // Find min and max prices
            let min_price_market = prices.iter().min_by(|a, b| 
                a.price.partial_cmp(&b.price).unwrap()).unwrap();
            let max_price_market = prices.iter().max_by(|a, b| 
                a.price.partial_cmp(&b.price).unwrap()).unwrap();
            
            let profit_percent = 
                (max_price_market.price - min_price_market.price) / 
                min_price_market.price * 100.0;
            
            if profit_percent >= self.min_profit_percent {
                opportunities.push(ArbitrageOpportunity {
                    token_mint: token.clone(),

                    sell_market: max_price_market.market.clone(),
                    buy_price: min_price_market.price,

        // Implementation would query multiple DEXs/markets
        // This is a simplified example
        Ok(vec![])

Running the Examples

To run the trading examples:

  1. Set up environment variables:

    cp .env.example .env
# Edit .env with your credentials

  2. Run the simple trade example:

    cargo run --example simple_trade

  3. Run with debug output:

    RUST_LOG=debug cargo run --example simple_trade

  4. Run specific trading strategy:

    cargo run --example grid_trading
cargo run --example dca_strategy  
cargo run --example stop_loss

Security Considerations

Never share sensitive information:

  • Private keys or seed phrases
  • Access tokens or refresh tokens
  • API credentials
  • Trading strategies or positions

Always verify before execution:

  • Transaction details and amounts
  • Recipient addresses and token mints
  • Slippage tolerance and fees
  • Market conditions and liquidity

Use appropriate security measures:

  • Hardware wallets for large amounts
  • Multi-signature wallets for institutional use
  • MEV protection services during high volatility
  • Regular security audits of trading strategies

Monitor for suspicious activity:

  • Unexpected price movements
  • Failed transactions or errors
  • Unusual network latency
  • Account access from unknown locations

The trading examples provide a comprehensive foundation for building sophisticated trading applications while maintaining security and reliability standards.

WebSocket Examples

This section demonstrates how to use WebSocket connections for real-time data streaming from Axiom Trade. WebSocket connections provide low-latency access to market updates, trade notifications, order status changes, and portfolio balance updates.

Table of Contents

Basic WebSocket Connection

The simplest way to establish a WebSocket connection and receive real-time updates.

Example: basic_websocket.rs

use axiomtrade_rs::websocket::{WebSocketClient, MessageHandler, WebSocketMessage};
use async_trait::async_trait;
use std::sync::Arc;
use std::time::Duration;
use tokio::time::sleep;

/// Simple message handler that prints incoming messages
struct BasicMessageHandler;

#[async_trait]
impl MessageHandler for BasicMessageHandler {
    async fn handle_message(&self, message: WebSocketMessage) {
        match message {
            WebSocketMessage::MarketUpdate(update) => {
                println!("Market Update: {} - ${:.6}", update.symbol, update.price_usd);
            }
            WebSocketMessage::OrderUpdate(order) => {
                println!("Order Update: {} - {:?}", order.order_id, order.status);
            }
            WebSocketMessage::TradeUpdate(trade) => {
                println!("Trade Update: {} - ${:.6}", trade.token_mint, trade.price);
            }
            WebSocketMessage::BalanceUpdate(balance) => {
                println!("Balance Update: {} SOL", balance.sol_balance);
            }
            WebSocketMessage::Connected { session_id } => {
                println!("Connected with session: {}", session_id);
            }
            WebSocketMessage::Disconnected { reason } => {
                println!("Disconnected: {}", reason);
            }
            WebSocketMessage::Error { code, message } => {
                println!("WebSocket Error {}: {}", code, message);
            }
            _ => {
                println!("Other message: {:?}", message);
            }
        }
    }

    async fn on_connected(&self, session_id: String) {
        println!("WebSocket connected! Session ID: {}", session_id);
    }

    async fn on_disconnected(&self, reason: String) {
        println!("WebSocket disconnected: {}", reason);
    }

    async fn on_error(&self, error: String) {
        println!("WebSocket error: {}", error);
    }
}

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load environment variables
    dotenvy::dotenv().ok();

    // Create message handler and WebSocket client
    let handler = Arc::new(BasicMessageHandler);
    let mut ws_client = WebSocketClient::new(handler.clone())?;
    
    // Connect to WebSocket (authentication is handled internally)
    ws_client.connect().await?;
    
    // Subscribe to new token listings
    ws_client.subscribe_new_tokens().await?;
    
    // Monitor the connection for 30 seconds
    let monitoring_duration = Duration::from_secs(30);
    let start_time = std::time::Instant::now();

    while start_time.elapsed() < monitoring_duration {
        if !ws_client.is_connected().await {
            println!("Connection lost, attempting reconnection...");
            ws_client.reconnect().await?;
        }
        sleep(Duration::from_millis(1000)).await;
    }

    // Graceful disconnect
    ws_client.disconnect().await;
    println!("WebSocket disconnected gracefully");

    Ok(())
}

Key Features:

  • Simple connection establishment with automatic authentication
  • Basic message handling for different event types
  • Connection health monitoring with automatic reconnection
  • Graceful disconnection

Price Subscriptions

Advanced example demonstrating subscription to multiple token price feeds with real-time tracking.

            }
            _ => {}
        }
    }

    async fn on_connected(&self, session_id: String) {
        println!("WebSocket connected! Session ID: {}", session_id);
    }

    async fn on_disconnected(&self, reason: String) {

MessageHandler Implementations

Default MessageHandler

The library provides a built-in DefaultMessageHandler for basic use cases:

#![allow(unused)]
fn main() {
use axiomtrade_rs::websocket::handler::DefaultMessageHandler;

// Create default handler that stores all updates
let handler = Arc::new(DefaultMessageHandler::new());
let ws_client = WebSocketClient::new(handler.clone())?;

// After some time, retrieve stored updates
let market_updates = handler.get_market_updates().await;
let order_updates = handler.get_order_updates().await;
let trade_updates = handler.get_trade_updates().await;
let balance_updates = handler.get_balance_updates().await;

// Clear stored data to manage memory
handler.clear_all().await;
}

Custom MessageHandler

Implement the MessageHandler trait for custom behavior:

#![allow(unused)]
fn main() {
use axiomtrade_rs::websocket::{MessageHandler, WebSocketMessage};
use async_trait::async_trait;

struct CustomHandler {
    // Your custom fields
}

#[async_trait]
impl MessageHandler for CustomHandler {
    async fn handle_message(&self, message: WebSocketMessage) {
        // Custom message processing logic
        match message {
            WebSocketMessage::MarketUpdate(update) => {
                // Process market updates
                self.process_market_data(update).await;
            }
            WebSocketMessage::OrderUpdate(order) => {
                // Handle order status changes
                self.update_order_status(order).await;
            }
            WebSocketMessage::TradeUpdate(trade) => {
                // Log trade executions
                self.log_trade(trade).await;
            }
            WebSocketMessage::BalanceUpdate(balance) => {
                // Update portfolio tracking
                self.update_portfolio(balance).await;
            }
            _ => {}
        }
    }

    async fn on_connected(&self, session_id: String) {
        // Connection established logic
        println!("Connected: {}", session_id);
    }

    async fn on_disconnected(&self, reason: String) {
        // Cleanup on disconnection
        println!("Disconnected: {}", reason);
    }

    async fn on_error(&self, error: String) {
        // Error handling
        eprintln!("Error: {}", error);
    }
}
}

Regional Selection

Choose optimal regions for better latency:

#![allow(unused)]
fn main() {
use axiomtrade_rs::websocket::{WebSocketClient, Region};

// Use specific region for better performance
let ws_client = WebSocketClient::with_region(handler, Region::USWest)?;

// Available regions:

// - Region::USCentral  
// - Region::USEast
// - Region::EUWest
// - Region::EUCentral
// - Region::EUEast

// Manual reconnection
if !is_connected {
    ws_client.reconnect().await?;
}

// Get current subscriptions
let subscriptions = ws_client.get_subscriptions().await;
println!("Active subscriptions: {:?}", subscriptions);

// Enable automatic token refresh
let ws_client = WebSocketClient::with_auto_refresh(handler, true)?;
}

Subscription Management

#![allow(unused)]
fn main() {
// Subscribe to different data feeds
ws_client.subscribe_new_tokens().await?;

Error Handling Best Practices

This guide covers comprehensive error handling strategies for axiomtrade-rs, including error types, Result handling patterns, retry logic, graceful degradation, and debugging approaches.

Error Type Hierarchy

Core Error Types

The axiomtrade-rs library uses a well-structured error hierarchy with the AxiomError enum as the central error type:

#![allow(unused)]
fn main() {
use thiserror::Error;

#[derive(Error, Debug)]
pub enum AxiomError {
    #[error("Authentication error: {0}")]
    Auth(#[from] crate::auth::error::AuthError),
    
    #[error("Network request failed: {0}")]
    Network(#[from] reqwest::Error),
    
    #[error("Serialization error: {0}")]
    Serialization(#[from] serde_json::Error),
    
    #[error("API error: {message}")]
    Api { message: String },
    
    #[error("Rate limit exceeded")]
    RateLimit,
    
    #[error("Service unavailable")]
    ServiceUnavailable,
    
    #[error("Timeout error")]
    Timeout,
    
    #[error("Configuration error: {0}")]
    Config(String),
    
    #[error("WebSocket error: {0}")]
    WebSocket(String),
}

pub type Result<T> = std::result::Result<T, AxiomError>;
}

Authentication Errors

Authentication errors are handled through a dedicated AuthError enum:

#![allow(unused)]
fn main() {
#[derive(Error, Debug)]
pub enum AuthError {
    #[error("Network request failed: {0}")]
    NetworkError(#[from] reqwest::Error),
    
    #[error("Invalid credentials")]
    InvalidCredentials,
    
    #[error("OTP required but not provided")]
    OtpRequired,
    
    #[error("Invalid OTP code")]
    InvalidOtp,
    
    #[error("Token expired")]
    TokenExpired,
    
    #[error("Token not found")]
    TokenNotFound,
    
    #[error("Email fetcher error: {0}")]
    EmailError(String),
    
    #[error("API error: {message}")]
    ApiError { message: String },
}
}

Client-Specific Errors

Enhanced client operations use EnhancedClientError for more specific error handling:

#![allow(unused)]
fn main() {
#[derive(Error, Debug)]
pub enum EnhancedClientError {
    #[error("Authentication error: {0}")]
    AuthError(#[from] AuthError),
    
    #[error("Network error: {0}")]
    NetworkError(#[from] reqwest::Error),
    
    #[error("Rate limit exceeded")]
    RateLimitExceeded,
    
    #[error("Max retries exceeded")]
    MaxRetriesExceeded,
    
    #[error("Request failed: {0}")]
    RequestFailed(String),
}
}

Result Handling Patterns

Basic Error Propagation

Use the ? operator for clean error propagation:

#![allow(unused)]
fn main() {
pub async fn get_portfolio_balance(&self, wallet: &str) -> Result<PortfolioData> {
    let auth_token = self.auth_client.get_valid_token().await?;
    let response = self.make_request("GET", &format!("/portfolio/{}", wallet), None).await?;
    let portfolio: PortfolioData = serde_json::from_value(response)?;
    Ok(portfolio)
}
}

Error Mapping and Context

Add context to errors using map_err:

#![allow(unused)]
fn main() {
pub async fn login(&mut self, email: &str, password: &str) -> Result<AuthTokens> {
    let response = self.client
        .post(&format!("{}/auth/login", self.base_url))
        .json(&login_request)
        .send()
        .await
        .map_err(|e| AxiomError::Network(e))?;
    
    let auth_data: AuthResponse = response
        .json()
        .await
        .map_err(|e| AxiomError::Serialization(serde_json::Error::from(e)))?;
    
    Ok(auth_data.into())
}
}

Handling Multiple Error Types

Pattern match on specific error types for different handling strategies:

#![allow(unused)]
fn main() {
pub async fn robust_api_call(&self, endpoint: &str) -> Result<Value> {
    match self.make_request(endpoint).await {
        Ok(response) => Ok(response),
        Err(AxiomError::Auth(AuthError::TokenExpired)) => {
            self.refresh_token().await?;
            self.make_request(endpoint).await
        },
        Err(AxiomError::RateLimit) => {
            tokio::time::sleep(Duration::from_secs(60)).await;
            self.make_request(endpoint).await
        },
        Err(e) => Err(e),
    }
}
}

Retry Logic Implementation

RetryConfig Structure

The library provides a comprehensive retry configuration system:

#![allow(unused)]
fn main() {
#[derive(Clone)]
pub struct RetryConfig {
    pub max_retries: u32,
    pub initial_delay: Duration,
    pub max_delay: Duration,
    pub exponential_base: f64,
    pub jitter: bool,
}

impl Default for RetryConfig {
    fn default() -> Self {
        Self {
            max_retries: 3,
            initial_delay: Duration::from_millis(100),
            max_delay: Duration::from_secs(30),
            exponential_base: 2.0,
            jitter: true,
        }
    }
}
}

Exponential Backoff with Jitter

The retry system implements exponential backoff with optional jitter to prevent thundering herd problems:

#![allow(unused)]
fn main() {
impl RetryConfig {
    fn calculate_delay(&self, attempt: u32) -> Duration {
        let base_delay = self.initial_delay.as_millis() as f64;
        let exponential_delay = base_delay * self.exponential_base.powi(attempt as i32);
        
        let mut delay_ms = exponential_delay.min(self.max_delay.as_millis() as f64);
        
        if self.jitter {
            use rand::Rng;
            let mut rng = rand::thread_rng();
            let jitter_factor = rng.gen_range(0.5..1.5);
            delay_ms *= jitter_factor;
        }
        
        Duration::from_millis(delay_ms as u64)
    }
}
}

Retryable Error Detection

Implement the RetryableError trait to determine which errors should trigger retries:

#![allow(unused)]
fn main() {
pub trait RetryableError {
    fn is_retryable(&self) -> bool;
}

impl RetryableError for reqwest::Error {
    fn is_retryable(&self) -> bool {
        if self.is_timeout() || self.is_connect() {
            return true;
        }
        
        if let Some(status) = self.status() {
            matches!(status.as_u16(), 429 | 500 | 502 | 503 | 504)
        } else {
            true
        }
    }
}

impl RetryableError for EnhancedClientError {
    fn is_retryable(&self) -> bool {
        match self {
            EnhancedClientError::NetworkError(e) => e.is_timeout() || e.is_connect(),
            EnhancedClientError::RateLimitExceeded => true,
            EnhancedClientError::RequestFailed(msg) => {
                msg.contains("timeout") || msg.contains("connection")
            }
            _ => false,
        }
    }
}
}

Using Retry Functions

Use the retry utilities for resilient operations:

#![allow(unused)]
fn main() {
use crate::utils::retry::{retry_with_config, RetryConfig};

pub async fn resilient_api_call(&self) -> Result<Value> {
    let retry_config = RetryConfig::default()
        .with_max_delay(Duration::from_secs(10))
        .with_jitter(true);

    retry_with_config(retry_config, || async {
        self.make_api_request("/some-endpoint").await
    }).await
}
}

Graceful Degradation Strategies

Service Availability Fallbacks

Implement fallback mechanisms when primary services are unavailable:

#![allow(unused)]
fn main() {
pub async fn get_token_price_with_fallback(&self, token: &str) -> Result<f64> {
    // Try primary price source
    match self.get_primary_price(token).await {
        Ok(price) => Ok(price),
        Err(AxiomError::ServiceUnavailable) => {
            // Fall back to secondary source
            self.get_fallback_price(token).await
        },
        Err(e) => Err(e),
    }
}

async fn get_fallback_price(&self, token: &str) -> Result<f64> {
    // Implement fallback price fetching logic
    // Could use different API, cached data, or estimated values
    Ok(0.0) // Placeholder
}
}

Partial Success Handling

Handle scenarios where some operations succeed and others fail:

#![allow(unused)]
fn main() {
pub async fn bulk_portfolio_update(&self, wallets: &[String]) -> PartialResult<Vec<PortfolioData>> {
    let mut successes = Vec::new();
    let mut failures = Vec::new();
    
    for wallet in wallets {
        match self.get_portfolio_balance(wallet).await {
            Ok(portfolio) => successes.push(portfolio),
            Err(e) => failures.push((wallet.clone(), e)),
        }
    }
    
    PartialResult {
        successes,
        failures,
        total_attempted: wallets.len(),
    }
}

pub struct PartialResult<T> {
    pub successes: Vec<T>,
    pub failures: Vec<(String, AxiomError)>,
    pub total_attempted: usize,
}

impl<T> PartialResult<T> {
    pub fn success_rate(&self) -> f64 {
        self.successes.len() as f64 / self.total_attempted as f64
    }
    
    pub fn has_any_success(&self) -> bool {
        !self.successes.is_empty()
    }
}
}

Circuit Breaker Pattern

Implement circuit breaker for failing services:

#![allow(unused)]
fn main() {
use std::sync::{Arc, Mutex};
use std::time::{Duration, Instant};

#[derive(Debug, Clone)]
pub enum CircuitState {
    Closed,    // Normal operation
    Open,      // Failing fast
    HalfOpen,  // Testing if service recovered
}

pub struct CircuitBreaker {
    state: Arc<Mutex<CircuitState>>,
    failure_count: Arc<Mutex<u32>>,
    last_failure_time: Arc<Mutex<Option<Instant>>>,
    failure_threshold: u32,
    recovery_timeout: Duration,
}

impl CircuitBreaker {
    pub fn new(failure_threshold: u32, recovery_timeout: Duration) -> Self {
        Self {
            state: Arc::new(Mutex::new(CircuitState::Closed)),
            failure_count: Arc::new(Mutex::new(0)),
            last_failure_time: Arc::new(Mutex::new(None)),
            failure_threshold,
            recovery_timeout,
        }
    }
    
    pub async fn call<F, T>(&self, operation: F) -> Result<T>
    where
        F: FnOnce() -> std::pin::Pin<Box<dyn std::future::Future<Output = Result<T>> + Send>>,
    {
        {
            let state = self.state.lock().unwrap();
            match *state {
                CircuitState::Open => {
                    if self.should_attempt_reset() {
                        drop(state);
                        *self.state.lock().unwrap() = CircuitState::HalfOpen;
                    } else {
                        return Err(AxiomError::ServiceUnavailable);
                    }
                }
                _ => {}
            }
        }
        
        match operation().await {
            Ok(result) => {
                self.on_success();
                Ok(result)
            }
            Err(e) => {
                self.on_failure();
                Err(e)
            }
        }
    }
    
    fn should_attempt_reset(&self) -> bool {
        if let Some(last_failure) = *self.last_failure_time.lock().unwrap() {
            Instant::now().duration_since(last_failure) >= self.recovery_timeout
        } else {
            false
        }
    }
    
    fn on_success(&self) {
        *self.state.lock().unwrap() = CircuitState::Closed;
        *self.failure_count.lock().unwrap() = 0;
    }
    
    fn on_failure(&self) {
        let mut failure_count = self.failure_count.lock().unwrap();
        *failure_count += 1;
        *self.last_failure_time.lock().unwrap() = Some(Instant::now());
        
        if *failure_count >= self.failure_threshold {
            *self.state.lock().unwrap() = CircuitState::Open;
        }
    }
}
}

Logging and Debugging

Structured Logging

Use structured logging for better error tracking:

#![allow(unused)]
fn main() {
use tracing::{error, warn, info, debug, span, Level};

pub async fn authenticated_request(&self, endpoint: &str) -> Result<Value> {
    let span = span!(Level::INFO, "authenticated_request", endpoint = endpoint);
    let _enter = span.enter();
    
    debug!("Starting authenticated request");
    
    match self.make_request(endpoint).await {
        Ok(response) => {
            info!("Request successful");
            Ok(response)
        }
        Err(e) => {
            error!(error = %e, "Request failed");
            
            // Log additional context based on error type
            match &e {
                AxiomError::Auth(auth_err) => {
                    warn!(auth_error = %auth_err, "Authentication error occurred");
                }
                AxiomError::RateLimit => {
                    warn!("Rate limit exceeded, consider implementing backoff");
                }
                AxiomError::Network(net_err) => {
                    warn!(network_error = %net_err, "Network connectivity issue");
                }
                _ => {}
            }
            
            Err(e)
        }
    }
}
}

Error Context and Tracing

Add context to errors for better debugging:

#![allow(unused)]
fn main() {
use anyhow::{Context, Result as AnyhowResult};

pub async fn complex_operation(&self, user_id: u64) -> AnyhowResult<ProcessedData> {
    let user_data = self.fetch_user_data(user_id).await
        .with_context(|| format!("Failed to fetch user data for user {}", user_id))?;
    
    let portfolio = self.get_portfolio(&user_data.wallet_address).await
        .with_context(|| format!("Failed to get portfolio for wallet {}", user_data.wallet_address))?;
    
    let processed = self.process_portfolio_data(&portfolio).await
        .context("Failed to process portfolio data")?;
    
    Ok(processed)
}
}

Debug Logging for Development

Implement debug logging that can be enabled in development:

#![allow(unused)]
fn main() {
#[cfg(debug_assertions)]
macro_rules! debug_log {
    ($($arg:tt)*) => {
        eprintln!("[DEBUG] {}: {}", chrono::Utc::now().format("%Y-%m-%d %H:%M:%S%.3f"), format!($($arg)*));
    };
}

#[cfg(not(debug_assertions))]
macro_rules! debug_log {
    ($($arg:tt)*) => {};
}

pub async fn debug_enabled_request(&self, endpoint: &str) -> Result<Value> {
    debug_log!("Making request to endpoint: {}", endpoint);
    
    let start_time = std::time::Instant::now();
    let result = self.make_request(endpoint).await;
    let duration = start_time.elapsed();
    
    match &result {
        Ok(_) => debug_log!("Request to {} completed successfully in {:?}", endpoint, duration),
        Err(e) => debug_log!("Request to {} failed after {:?}: {}", endpoint, duration, e),
    }
    
    result
}
}

Error Handling Best Practices

1. Fail Fast Principle

Validate inputs early and return errors immediately:

#![allow(unused)]
fn main() {
pub async fn create_trade_order(&self, amount: f64, token_address: &str) -> Result<TradeOrder> {
    // Validate inputs early
    if amount <= 0.0 {
        return Err(AxiomError::Config("Amount must be positive".to_string()));
    }
    
    if token_address.len() != 44 {
        return Err(AxiomError::Config("Invalid token address format".to_string()));
    }
    
    // Proceed with operation
    self.execute_trade(amount, token_address).await
}
}

2. Specific Error Types

Use specific error types rather than generic strings:

#![allow(unused)]
fn main() {
// Good: Specific error types
#[derive(Error, Debug)]
pub enum TradeError {
    #[error("Insufficient balance: required {required}, available {available}")]
    InsufficientBalance { required: f64, available: f64 },
    
    #[error("Invalid token address: {address}")]
    InvalidTokenAddress { address: String },
    
    #[error("Slippage tolerance exceeded: expected {expected}%, actual {actual}%")]
    SlippageExceeded { expected: f64, actual: f64 },
}

// Bad: Generic string errors
fn bad_example() -> Result<()> {
    Err(AxiomError::Config("Something went wrong".to_string()))
}
}

3. Error Recovery Strategies

Implement appropriate recovery strategies for different error types:

#![allow(unused)]
fn main() {
pub async fn resilient_portfolio_fetch(&self, wallet: &str, max_retries: u32) -> Result<Portfolio> {
    for attempt in 0..max_retries {
        match self.get_portfolio(wallet).await {
            Ok(portfolio) => return Ok(portfolio),
            Err(AxiomError::RateLimit) => {
                // Wait longer for rate limits
                let delay = Duration::from_secs(60 * (attempt + 1) as u64);
                tokio::time::sleep(delay).await;
            }
            Err(AxiomError::Network(_)) => {
                // Shorter wait for network issues
                let delay = Duration::from_millis(1000 * (attempt + 1) as u64);
                tokio::time::sleep(delay).await;
            }
            Err(AxiomError::Auth(_)) => {
                // Try to refresh authentication
                self.refresh_auth().await?;
            }
            Err(e) => {
                // Non-recoverable errors
                return Err(e);
            }
        }
    }
    
    Err(AxiomError::Config("Max retries exceeded".to_string()))
}
}

4. Resource Cleanup

Ensure proper resource cleanup even when errors occur:

#![allow(unused)]
fn main() {
pub async fn websocket_with_cleanup(&self) -> Result<Vec<Message>> {
    let ws_connection = self.connect_websocket().await?;
    let mut messages = Vec::new();
    
    let result = async {
        loop {
            match ws_connection.next().await {
                Some(Ok(message)) => messages.push(message),
                Some(Err(e)) => return Err(AxiomError::WebSocket(e.to_string())),
                None => break,
            }
        }
        Ok(messages)
    }.await;
    
    // Ensure connection is properly closed regardless of success/failure
    if let Err(e) = ws_connection.close().await {
        warn!("Failed to close WebSocket connection: {}", e);
    }
    
    result
}
}

5. Testing Error Scenarios

Write comprehensive tests for error conditions:

#![allow(unused)]
fn main() {
#[cfg(test)]
mod tests {
    use super::*;
    use tokio_test;
    
    #[tokio::test]
    async fn test_retry_on_rate_limit() {
        let mut client = MockClient::new();
        
        // First call returns rate limit error
        client.expect_get_portfolio()
            .times(1)
            .returning(|_| Err(AxiomError::RateLimit));
        
        // Second call succeeds
        client.expect_get_portfolio()
            .times(1)
            .returning(|_| Ok(Portfolio::default()));
        
        let result = client.resilient_portfolio_fetch("test_wallet", 2).await;
        assert!(result.is_ok());
    }
    
    #[tokio::test]
    async fn test_non_retryable_error() {
        let mut client = MockClient::new();
        
        client.expect_get_portfolio()
            .times(1)
            .returning(|_| Err(AxiomError::Config("Invalid wallet".to_string())));
        
        let result = client.resilient_portfolio_fetch("invalid_wallet", 3).await;
        assert!(result.is_err());
        
        // Should not retry non-retryable errors
        assert_eq!(client.call_count(), 1);
    }
}
}

Monitoring and Alerting

Error Metrics Collection

Implement error metrics for monitoring:

#![allow(unused)]
fn main() {
use std::sync::atomic::{AtomicU64, Ordering};
use std::collections::HashMap;
use std::sync::Arc;

pub struct ErrorMetrics {
    error_counts: Arc<HashMap<String, AtomicU64>>,
    total_requests: AtomicU64,
    successful_requests: AtomicU64,
}

impl ErrorMetrics {
    pub fn new() -> Self {
        Self {
            error_counts: Arc::new(HashMap::new()),
            total_requests: AtomicU64::new(0),
            successful_requests: AtomicU64::new(0),
        }
    }
    
    pub fn record_request_success(&self) {
        self.total_requests.fetch_add(1, Ordering::Relaxed);
        self.successful_requests.fetch_add(1, Ordering::Relaxed);
    }
    
    pub fn record_request_error(&self, error_type: &str) {
        self.total_requests.fetch_add(1, Ordering::Relaxed);
        // Note: This is simplified - in practice, you'd need thread-safe HashMap updates
    }
    
    pub fn get_error_rate(&self) -> f64 {
        let total = self.total_requests.load(Ordering::Relaxed);
        let successful = self.successful_requests.load(Ordering::Relaxed);
        
        if total == 0 {
            0.0
        } else {
            1.0 - (successful as f64 / total as f64)
        }
    }
}
}

Health Check Endpoints

Implement health checks that consider error rates:

#![allow(unused)]
fn main() {
#[derive(serde::Serialize)]
pub struct HealthStatus {
    pub status: String,
    pub error_rate: f64,
    pub recent_errors: Vec<String>,
    pub uptime_seconds: u64,
}

impl AxiomClient {
    pub async fn health_check(&self) -> HealthStatus {
        let error_rate = self.metrics.get_error_rate();
        
        let status = if error_rate > 0.5 {
            "unhealthy"
        } else if error_rate > 0.1 {
            "degraded"
        } else {
            "healthy"
        }.to_string();
        
        HealthStatus {
            status,
            error_rate,
            recent_errors: self.get_recent_errors(),
            uptime_seconds: self.get_uptime().as_secs(),
        }
    }
}
}

Conclusion

Effective error handling in axiomtrade-rs requires:

  1. Structured Error Types: Use the provided error hierarchy with specific, actionable error types
  2. Robust Retry Logic: Implement exponential backoff with jitter for retryable errors
  3. Graceful Degradation: Provide fallbacks and partial success handling
  4. Comprehensive Logging: Use structured logging with appropriate context
  5. Proactive Monitoring: Collect metrics and implement health checks
  6. Thorough Testing: Test error scenarios and recovery strategies

By following these patterns, you can build resilient applications that handle failures gracefully and provide excellent user experience even when things go wrong.

Rate Limiting

Overview

Rate limiting is a critical component for managing API requests and ensuring stable operation within Axiom Trade's API limits. The axiomtrade-rs library provides three distinct rate limiting implementations to handle different scenarios and requirements.

Rate Limiting Implementations

1. Window-Based Rate Limiter

The RateLimiter uses a sliding window approach to track requests over a specified time period.

#![allow(unused)]
fn main() {
use axiomtrade_rs::utils::RateLimiter;
use std::time::Duration;

// Allow 100 requests per minute
let limiter = RateLimiter::new(100, Duration::from_secs(60));

// Wait if necessary before making a request
limiter.wait_if_needed().await;
}

Key Features:

  • Sliding window implementation using VecDeque
  • Thread-safe with Arc<RwLock>
  • Automatic cleanup of expired requests
  • Non-blocking permission acquisition

Configuration Parameters:

  • max_requests: Maximum number of requests allowed in the window
  • window: Time duration for the rate limit window

2. Token Bucket Rate Limiter

The BucketRateLimiter implements a token bucket algorithm for more flexible rate limiting with burst capabilities.

#![allow(unused)]
fn main() {
use axiomtrade_rs::utils::BucketRateLimiter;

// Allow 10 tokens with refill rate of 1 token per second
let bucket = BucketRateLimiter::new(10.0, 1.0);

// Consume 2 tokens
bucket.consume(2.0).await;
}

Key Features:

  • Token bucket algorithm with configurable refill rate
  • Supports burst requests up to bucket capacity
  • Fractional token consumption
  • Automatic token refill based on elapsed time

Configuration Parameters:

  • max_tokens: Maximum bucket capacity
  • refill_rate: Tokens added per second

3. Endpoint-Specific Rate Limiter

The EndpointRateLimiter provides per-endpoint rate limiting with fallback to default limits.

#![allow(unused)]
fn main() {
use axiomtrade_rs::utils::EndpointRateLimiter;
use std::time::Duration;

let endpoint_limiter = EndpointRateLimiter::new();

// Add specific limit for trading endpoint
endpoint_limiter.add_endpoint_limit(
    "/api/v1/trade".to_string(),
    50,
    Duration::from_secs(60)
).await;

// Wait for endpoint-specific limit
endpoint_limiter.wait_for_endpoint("/api/v1/trade").await;
}

Key Features:

  • Per-endpoint rate limiting configuration
  • Default rate limiter fallback (100 requests/minute)
  • Dynamic endpoint limit addition
  • Automatic endpoint-specific limit enforcement

Configurable Limits

Endpoint CategoryRecommended LimitWindowRationale
Authentication10 requests/minute60sPrevent brute force attacks
Trading50 requests/minute60sBalance speed with stability
Portfolio100 requests/minute60sAllow frequent balance checks
Market Data200 requests/minute60sHigh-frequency data needs
WebSocketNo limitN/AReal-time streaming

Environment-Based Configuration

#![allow(unused)]
fn main() {
// Production limits (conservative)
let auth_limiter = RateLimiter::new(10, Duration::from_secs(60));
let trading_limiter = RateLimiter::new(50, Duration::from_secs(60));

// Development limits (more permissive)
let dev_limiter = RateLimiter::new(1000, Duration::from_secs(60));
}

Backoff Strategies

Linear Backoff

The basic rate limiters implement linear backoff by calculating exact wait times.

#![allow(unused)]
fn main() {
let wait_time = limiter.acquire().await;
if wait_time > Duration::ZERO {
    tokio::time::sleep(wait_time).await;
}
}

For API errors, implement exponential backoff in conjunction with rate limiting:

#![allow(unused)]
fn main() {
use std::cmp::min;

async fn make_request_with_backoff(limiter: &RateLimiter) -> Result<Response, Error> {
    let mut attempts = 0;
    let max_attempts = 5;
    
    loop {
        limiter.wait_if_needed().await;
        
        match api_request().await {
            Ok(response) => return Ok(response),
            Err(error) if attempts < max_attempts => {
                let delay = Duration::from_millis(100 * 2_u64.pow(attempts));
                let jitter = Duration::from_millis(rand::random::<u64>() % 100);
                tokio::time::sleep(delay + jitter).await;
                attempts += 1;
            }
            Err(error) => return Err(error),
        }
    }
}
}

Circuit Breakers

While not implemented in the current rate limiters, circuit breakers can be combined with rate limiting for enhanced reliability:

#![allow(unused)]
fn main() {
use std::sync::atomic::{AtomicU32, Ordering};

struct CircuitBreaker {
    failure_count: AtomicU32,
    failure_threshold: u32,
    recovery_timeout: Duration,
    last_failure: std::sync::Mutex<Option<Instant>>,
}

impl CircuitBreaker {
    fn is_open(&self) -> bool {
        let count = self.failure_count.load(Ordering::Relaxed);
        if count >= self.failure_threshold {
            if let Ok(last_failure) = self.last_failure.lock() {
                if let Some(time) = *last_failure {
                    return time.elapsed() < self.recovery_timeout;
                }
            }
        }
        false
    }
    
    fn record_success(&self) {
        self.failure_count.store(0, Ordering::Relaxed);
    }
    
    fn record_failure(&self) {
        self.failure_count.fetch_add(1, Ordering::Relaxed);
        if let Ok(mut last_failure) = self.last_failure.lock() {
            *last_failure = Some(Instant::now());
        }
    }
}
}

Best Practices

1. Choose the Right Rate Limiter

  • Window-based (RateLimiter): Use for consistent request rates
  • Token bucket (BucketRateLimiter): Use when burst requests are acceptable
  • Endpoint-specific (EndpointRateLimiter): Use for APIs with different limits per endpoint

2. Monitor Rate Limit Usage

#![allow(unused)]
fn main() {
let current_requests = limiter.get_request_count().await;
let utilization = (current_requests as f64 / max_requests as f64) * 100.0;

if utilization > 80.0 {
    log::warn!("Rate limit utilization high: {:.1}%", utilization);
}
}

3. Implement Graceful Degradation

#![allow(unused)]
fn main() {
async fn make_request_with_fallback(limiter: &RateLimiter) -> Result<Response, Error> {
    let wait_time = limiter.acquire().await;
    
    if wait_time > Duration::from_secs(5) {
        // If wait time is too long, use cached data or simplified response
        return get_cached_response().await;
    }
    
    if wait_time > Duration::ZERO {
        tokio::time::sleep(wait_time).await;
    }
    
    api_request().await
}
}

4. Use Jitter for Distributed Systems

When multiple clients are involved, add jitter to prevent thundering herd:

#![allow(unused)]
fn main() {
use rand::Rng;

async fn wait_with_jitter(base_duration: Duration) {
    let jitter_ms = rand::thread_rng().gen_range(0..=100);
    let jitter = Duration::from_millis(jitter_ms);
    tokio::time::sleep(base_duration + jitter).await;
}
}

5. Configure Based on Environment

#![allow(unused)]
fn main() {
fn create_rate_limiter_for_env() -> RateLimiter {
    match std::env::var("ENVIRONMENT").as_deref() {
        Ok("production") => RateLimiter::new(50, Duration::from_secs(60)),
        Ok("staging") => RateLimiter::new(100, Duration::from_secs(60)),
        _ => RateLimiter::new(200, Duration::from_secs(60)), // development
    }
}
}

6. Reset Rate Limiters When Appropriate

#![allow(unused)]
fn main() {
// Reset rate limiter after authentication renewal
if token_renewed {
    limiter.reset().await;
}
}

7. Log Rate Limiting Events

#![allow(unused)]
fn main() {
let wait_time = limiter.acquire().await;
if wait_time > Duration::ZERO {
    log::info!("Rate limited: waiting {:?}", wait_time);
}
}

Integration with Axiom Client

The Axiom client integrates rate limiting at multiple levels:

#![allow(unused)]
fn main() {
use axiomtrade_rs::client::EnhancedClient;

let client = EnhancedClient::builder()
    .with_rate_limiting(true)
    .with_trading_rate_limit(50, Duration::from_secs(60))
    .with_portfolio_rate_limit(100, Duration::from_secs(60))
    .build()?;
}

Performance Considerations

Memory Usage

  • Window-based rate limiter: O(n) where n is max_requests
  • Token bucket: O(1) constant memory
  • Endpoint-specific: O(m) where m is number of endpoints

CPU Overhead

  • Window cleanup: O(k) where k is expired requests
  • Token calculation: O(1) constant time
  • Lock contention: Minimized with RwLock

Recommendations

  1. Use token bucket for high-frequency operations
  2. Clean up endpoint limiters periodically in long-running applications
  3. Monitor lock contention in highly concurrent scenarios
  4. Consider using Arc::clone() instead of sharing references

Testing Rate Limiters

#![allow(unused)]
fn main() {
#[tokio::test]
async fn test_rate_limiter_behavior() {
    let limiter = RateLimiter::new(2, Duration::from_secs(1));
    
    // First two requests should be immediate
    assert_eq!(limiter.acquire().await, Duration::ZERO);
    assert_eq!(limiter.acquire().await, Duration::ZERO);
    
    // Third request should require waiting
    let wait_time = limiter.acquire().await;
    assert!(wait_time > Duration::ZERO);
}
}

Troubleshooting

Common Issues

  1. Requests still blocked after wait: Check system clock synchronization
  2. High memory usage: Verify window cleanup is working properly
  3. Inconsistent behavior: Ensure thread-safe access patterns
  4. Performance degradation: Monitor lock contention and consider alternatives

Debug Information

#![allow(unused)]
fn main() {
// Check current state
let request_count = limiter.get_request_count().await;
println!("Current requests in window: {}", request_count);

// Reset if needed
if request_count > expected_max {
    limiter.reset().await;
}
}

Rate limiting is essential for building robust, production-ready trading applications. By implementing appropriate rate limiting strategies, you can ensure reliable operation within API constraints while maintaining optimal performance.

Security Best Practices

This document outlines the comprehensive security practices implemented in axiomtrade-rs, based on analysis of the codebase's security patterns and mechanisms.

Overview

The axiomtrade-rs library implements multiple layers of security to protect user credentials, tokens, and trading operations. Security measures span credential management, cryptographic operations, secure communications, and MEV protection.

1. Credential Management

Password Security

The library uses industry-standard PBKDF2 password hashing with SHA256:

  • Hash Function: PBKDF2-HMAC-SHA256
  • Iterations: 600,000 (exceeds OWASP recommendations)
  • Salt: 32-byte fixed salt for deterministic hashing
  • Output: Base64-encoded 32-byte hash
#![allow(unused)]
fn main() {
// Example from src/utils/password.rs
const ITERATIONS: u32 = 600000;
pub fn hashpassword(password: &str) -> String {
    let mut derived_key = [0u8; 32];
    pbkdf2_hmac::<Sha256>(password.as_bytes(), &SALT, ITERATIONS, &mut derived_key);
    general_purpose::STANDARD.encode(&derived_key)
}
}

Security Benefits:

  • Resistance to brute-force attacks through high iteration count
  • Deterministic hashing enables consistent authentication
  • SHA256 provides cryptographic strength
  • No plain-text password storage

Environment Variable Safety

Custom environment loader handles special characters securely:

  • Parsing: Safe parsing of .env files with quote handling
  • Special Characters: Proper handling of passwords containing $, !, etc.
  • Validation: Required variable checking with clear error messages
  • Isolation: Environment variables don't leak into process space
#![allow(unused)]
fn main() {
// Safe environment variable loading
let loader = EnvLoader::from_file(Path::new(".env"))?;
let password = loader.get_required("AXIOM_PASSWORD")?;
}

Best Practices:

  • Store sensitive credentials in .env files, not in code
  • Use quotes for values containing special characters
  • Never commit .env files to version control
  • Validate required environment variables at startup

2. Token Security

JWT Token Management

Comprehensive token lifecycle management with secure storage:

#![allow(unused)]
fn main() {
pub struct AuthTokens {
    pub access_token: String,
    pub refresh_token: String,
    pub expires_at: Option<chrono::DateTime<chrono::Utc>>,
}
}

Security Features:

  • Expiration Tracking: Automatic token expiry detection with buffer zones
  • Refresh Logic: Proactive token refresh 15 minutes before expiry
  • Secure Storage: Optional persistent storage with file-based caching
  • Memory Safety: Thread-safe in-memory token management

Session Security

Enhanced session management with multiple authentication layers:

#![allow(unused)]
fn main() {
pub struct AuthSession {
    pub tokens: AuthTokens,           // JWT tokens
    pub cookies: AuthCookies,         // HTTP session cookies
    pub turnkey_session: Option<TurnkeySession>, // Wallet management
    pub user_info: Option<UserInfo>,  // User metadata
    pub session_metadata: SessionMetadata, // Tracking data
}
}

Security Measures:

  • Multi-Factor Authentication: Combines JWTs and HTTP cookies
  • Session Tracking: Metadata for debugging and security monitoring
  • Automatic Cleanup: Session invalidation on logout
  • Secure Headers: Proper cookie formatting for HTTP security

HTTP cookies managed with security-first approach:

#![allow(unused)]
fn main() {
pub struct AuthCookies {
    pub auth_access_token: Option<String>,    // HttpOnly token
    pub auth_refresh_token: Option<String>,   // HttpOnly refresh
    pub g_state: Option<String>,              // Google state
    pub additional_cookies: HashMap<String, String>,
}
}

Implementation Details:

  • HttpOnly Flags: Prevents JavaScript access to sensitive tokens
  • Secure Transmission: Cookies sent only over HTTPS
  • State Management: Google OAuth state tracking
  • Flexible Storage: Support for additional session cookies

3. Cryptographic Security

P256 Key Management

Advanced elliptic curve cryptography for wallet operations:

#![allow(unused)]
fn main() {
pub struct P256KeyPair {
    pub private_key: String,    // Hex-encoded private key
    pub public_key: String,     // Compressed public key

  • Password-Derived Keys: PBKDF2-based key generation
  • Deterministic Generation: Reproducible keys from password + salt
  • WebAuthn Support: Compatible signature formats

Key Generation Security

Multi-layer key derivation process:

  1. Password Input: User-provided password
  2. Salt Generation: Random 32-byte salt (or provided salt)
  3. PBKDF2 Derivation: 600,000 iterations with SHA256
  4. Curve Validation: Ensure key falls within valid P-256 range
  5. Key Pair Creation: Generate public key from private key

Security Validations:

  • Curve order validation prevents invalid keys
  • Zero-key rejection ensures cryptographic strength
  • Retry mechanism for edge cases
  • Deterministic regeneration from client secret

Digital Signatures

Dual signature formats for different use cases:

#![allow(unused)]
fn main() {
// DER format for general use
pub fn sign_message(message: &[u8], private_key_hex: &str) -> Result<Vec<u8>>

// WebAuthn format for browser compatibility
pub fn sign_message_webauthn(message: &[u8], private_key_hex: &str) -> Result<Vec<u8>>
}

Security Properties:

  • ECDSA Signatures: Cryptographically secure signing
  • Format Flexibility: DER and raw signature support

Async/Await Best Practices

1. Efficient Task Spawning

Use tokio::spawn for CPU-intensive tasks and concurrent operations:

#![allow(unused)]
fn main() {
// Good: Spawn independent tasks
let handles: Vec<_> = wallet_addresses.iter().map(|address| {
    let client = client.clone();
    let address = address.clone();
    tokio::spawn(async move {
        client.get_balance(&address).await
    })
}).collect();

// Wait for all tasks to complete
let results = futures_util::future::try_join_all(handles).await?;
}

2. Avoid Blocking in Async Context

#![allow(unused)]
fn main() {
// Bad: Blocking I/O in async context
async fn bad_example() {
    std::fs::read_to_string("file.json").unwrap(); // Blocks entire runtime
}

// Good: Use async I/O
async fn good_example() {
    tokio::fs::read_to_string("file.json").await.unwrap();
}
}

3. Strategic Use of Arc and RwLock

#![allow(unused)]
fn main() {
pub struct EnhancedClient {
    auth_client: Arc<RwLock<AuthClient>>,
    rate_limiter: EndpointRateLimiter,
    global_rate_limiter: RateLimiter,
}

// Minimize lock contention
impl EnhancedClient {
    pub async fn make_request(&self, method: Method, url: &str) -> Result<Response> {
        // Check rate limits first (no lock needed)
        self.global_rate_limiter.wait_if_needed().await;
        
        // Only acquire lock when needed
        let auth_client = Arc::clone(&self.auth_client);
        let result = retry_with_config(self.retry_config.clone(), || {
            let auth_client = Arc::clone(&auth_client);
            async move {
                auth_client.write().await
                    .make_authenticated_request(method, url, body)
                    .await
            }
        }).await?;
        
        result
    }
}
}

4. Efficient Error Handling

            EnhancedClientError::RateLimitExceeded => true,
            _ => false,
        }
    }
}

// Use custom retry logic for better performance
pub async fn retry_with_backoff<F, Fut, T, E>(
    config: RetryConfig,
    mut operation: F,
) -> Result<T, E>
where
    F: FnMut() -> Fut,
    Fut: Future<Output = Result<T, E>>,
    E: RetryableError,
{
    for attempt in 0..=config.max_retries {
        match operation().await {
            Ok(result) => return Ok(result),
            Err(error) => {
                if !error.is_retryable() || attempt == config.max_retries {
                    return Err(error);
                }
                
                let delay = config.calculate_delay(attempt);
                tokio::time::sleep(delay).await;
            }
        }
    }
}
}

}

impl WebSocketClient {
    // Use multiple endpoints for redundancy
    fn get_random_url(&self) -> &'static str {
        let urls = match self.region {
            Region::USWest => vec!["socket8.axiom.trade", "cluster-usw2.axiom.trade"],
            Region::USCentral => vec!["cluster3.axiom.trade", "cluster-usc2.axiom.trade"],
            // ...
        };
        urls[fastrand::usize(0..urls.len())]
    }
    
    // Automatic token refresh
    fn spawn_token_refresh_task(&self) {
        let auth_client = Arc::clone(&self.auth_client);
        let is_connected = Arc::clone(&self.is_connected);
        
        tokio::spawn(async move {
            let mut refresh_interval = interval(Duration::from_secs(600));
            
            loop {
                refresh_interval.tick().await;
                
                if !*is_connected.read().await {
                    break;
                }
                
                if let Err(e) = auth_client.write().await.ensure_valid_authentication().await {
                    *is_connected.write().await = false;
                    break;
                }
            }
        });
    }
}
}

3. Session Management

}

impl SessionManager {
    // Efficient session validation
    pub async fn is_session_valid(&self) -> bool {
        let guard = self.session.read().await;
        guard.as_ref().map_or(false, |session| session.is_valid())
    }
    
    // Batch operations for session updates
    pub async fn update_session_data(

        }
        
        if self.auto_save {
            self.save_session().await?;
        }
        
        Ok(())
    }

fn main() {
// Instead of individual queries
pub async fn get_balances_inefficient(
    &self, 
    addresses: &[String]
) -> Result<Vec<Balance>, PortfolioError> {
    let mut balances = Vec::new();
    for address in addresses {
        let balance = self.get_balance(address).await?; // N API calls
        balances.push(balance);
    }
    Ok(balances)
}

// Use batch endpoint
pub async fn get_batch_balance(
    &self,
    wallet_addresses: &[String],

    let request_body = json!({
        "wallets": wallet_addresses
    });
    
    self.client
        .make_json_request(Method::POST, "/portfolio/batch-balance", Some(request_body))
        .await
        .map_err(PortfolioError::from)
}
}

2. Concurrent Processing

    items: Vec<T>,
    concurrency_limit: usize,
    processor: F,
) -> Vec<Result<F::Output, F::Error>>
where
    F: Fn(T) -> Fut + Clone + Send + 'static,
    Fut: Future<Output = Result<F::Output, F::Error>> + Send,
    T: Send + 'static,
{
    let semaphore = Arc::new(Semaphore::new(concurrency_limit));
    let tasks: Vec<_> = items.into_iter().map(|item| {
        let semaphore = Arc::clone(&semaphore);
        let processor = processor.clone();
        
        tokio::spawn(async move {

    fn add_tick(&mut self, tick: MarketTick) {
        if self.ticks.len() >= self.max_size {
            self.ticks.pop_front(); // Remove oldest
        }
        self.ticks.push_back(tick);
    }
}
}

2. Zero-Copy Patterns

#![allow(unused)]
fn main() {
// Use references instead of cloning
pub fn process_market_data(data: &[MarketTick]) -> MarketState {
    let mut total_volume = 0.0;
    let mut price_sum = 0.0;
    
    for tick in data.iter() {  // Iterator over references
        total_volume += tick.quantity;
        price_sum += tick.price;
    }
    
    MarketState {
        avg_price: price_sum / data.len() as f64,
        total_volume,
    }
}
}

3. Memory Pool Usage

            .collect();
        let free_indices = (0..capacity).collect();
        
        Self { orders, free_indices }
    }
    
    pub fn acquire(&mut self) -> Option<&mut Order> {
        self.free_indices.pop()
            .map(|idx| &mut self.orders[idx])
    }
    
    pub fn release(&mut self, order: &Order) {
        if let Some(idx) = self.orders.iter().position(|o| std::ptr::eq(o, order)) {
            self.orders[idx].reset();
            self.free_indices.push(idx);

        let tokens_to_add = (elapsed * self.refill_rate).min(self.max_tokens - *tokens);
        *tokens = (*tokens + tokens_to_add).min(self.max_tokens);
        *last_refill = now;
        
        if *tokens >= tokens_needed {
            *tokens -= tokens_needed;
            None
        } else {
            let tokens_deficit = tokens_needed - *tokens;
            let wait_time = Duration::from_secs_f64(tokens_deficit / self.refill_rate);

Debugging Guide

This guide provides comprehensive debugging techniques for axiomtrade-rs, covering logging configuration, network inspection, WebSocket debugging, and common error pattern identification.

Enable Debug Logging

Basic Logging Setup

The axiomtrade-rs library uses the tracing crate for structured logging. To enable debug logging in your application:

use tracing::{info, debug, error, warn};
use tracing_subscriber::{layer::SubscriberExt, util::SubscriberInitExt};

fn init_logging() {
    tracing_subscriber::registry()
        .with(
            tracing_subscriber::EnvFilter::try_from_default_env()
                .unwrap_or_else(|_| "axiomtrade_rs=debug,info".into()),
        )
        .with(tracing_subscriber::fmt::layer())
        .init();
}

fn main() {
    init_logging();
    // Your application code here
}

Log Levels

Configure different log levels for different components:

#![allow(unused)]
fn main() {
// Maximum verbosity - shows all internal operations
tracing_subscriber::EnvFilter::new("axiomtrade_rs=trace,debug")

// Standard debugging - shows important operations and errors
tracing_subscriber::EnvFilter::new("axiomtrade_rs=debug,info")

// Production logging - errors and warnings only
tracing_subscriber::EnvFilter::new("axiomtrade_rs=warn,error")
}

Structured Logging

Use structured logging to capture context:

#![allow(unused)]
fn main() {
use tracing::{info, error, Span, span, Level};

let span = span!(Level::INFO, "trading_operation", 
    operation = "buy", 
    token = "SOL", 
    amount = 1.0
);
let _enter = span.enter();

info!("Starting trade execution");
// Trading logic here
}

Using RUST_LOG Environment Variable

Basic Configuration

Set the RUST_LOG environment variable to control logging verbosity:

# Windows Command Prompt
set RUST_LOG=axiomtrade_rs=debug
cargo run --example trading_demo

# Windows PowerShell
$env:RUST_LOG="axiomtrade_rs=debug"
cargo run --example trading_demo

# Linux/macOS
export RUST_LOG=axiomtrade_rs=debug
cargo run --example trading_demo

Advanced RUST_LOG Patterns

# Enable debug logging for all modules
RUST_LOG=debug

# Enable specific module logging
RUST_LOG=axiomtrade_rs::auth=debug,axiomtrade_rs::websocket=trace

# Enable reqwest HTTP client debugging
RUST_LOG=axiomtrade_rs=debug,reqwest=debug,hyper=debug

# Filter by specific operations
RUST_LOG=axiomtrade_rs::trading=debug,axiomtrade_rs::portfolio=info

# Exclude noisy modules
RUST_LOG=debug,h2=off,rustls=off

Environment-Specific Configurations

Create different logging configurations for different environments:

# Development
RUST_LOG=axiomtrade_rs=debug,reqwest=debug

# Testing
RUST_LOG=axiomtrade_rs=trace,test

# Production
RUST_LOG=axiomtrade_rs=warn,error

Inspecting Network Requests

HTTP Request Debugging

Enable detailed HTTP request/response logging:

#![allow(unused)]
fn main() {
use reqwest::Client;
use tracing::{debug, info};

// In your client configuration
let client = Client::builder()
    .connection_verbose(true)  // Enable connection debugging
    .build()?;

// Log requests manually
debug!(
    method = %request.method(),
    url = %request.url(),
    headers = ?request.headers(),
    "Sending HTTP request"
);

let response = client.execute(request).await?;

debug!(
    status = %response.status(),
    headers = ?response.headers(),
    "Received HTTP response"
);
}

Request/Response Interception

Create a middleware to log all API calls:

#![allow(unused)]
fn main() {
use reqwest::{Request, Response};
use tracing::{debug, error};

pub async fn log_request_response(
    request: Request,
    client: &Client,
) -> Result<Response, reqwest::Error> {
    let url = request.url().clone();
    let method = request.method().clone();
    
    debug!(
        method = %method,
        url = %url,
        "Sending request to Axiom API"
    );
    
    let start_time = std::time::Instant::now();
    let response = client.execute(request).await;
    let duration = start_time.elapsed();
    
    match &response {
        Ok(resp) => {
            debug!(
                status = %resp.status(),
                duration_ms = duration.as_millis(),
                "Received response from Axiom API"
            );
        }
        Err(e) => {
            error!(
                error = %e,
                duration_ms = duration.as_millis(),
                "Request failed"
            );
        }
    }
    
    response
}
}

Capture Full Request/Response Bodies

#![allow(unused)]
fn main() {
use tracing::debug;

// For debugging authentication issues
let body = response.text().await?;
debug!(
    response_body = %body,
    "Full response body received"
);

// For request body debugging
let request_body = serde_json::to_string(&payload)?;
debug!(
    request_body = %request_body,
    "Sending request body"
);
}

Network-Level Debugging

For deeper network inspection, use external tools:

# Using curl to replicate requests
curl -X POST "https://api.axiom.trade/auth/login" \
     -H "Content-Type: application/json" \
     -H "User-Agent: axiomtrade-rs/1.0.0" \
     -d '{"email":"user@example.com","password_hash":"..."}' \
     -v

# Using tcpdump to capture network traffic (Linux/macOS)

Debugging Strategies

  1. Start with Basic Logging: Enable RUST_LOG=debug to see general operation flow
  2. Isolate Components: Test authentication, WebSocket, and trading separately
  3. Check Network Layer: Use external tools to verify API endpoints
  4. Monitor Resource Usage: Check memory and CPU usage during operations
  5. Test with Minimal Examples: Create simple reproduction cases
  6. Compare with Python Implementation: Use the oldstuff/axiompy reference

Performance Debugging

#![allow(unused)]
fn main() {
use std::time::Instant;
use tracing::{debug, warn};

// Measure operation performance
let start = Instant::now();
let result = some_expensive_operation().await;
let duration = start.elapsed();

if duration > Duration::from_millis(1000) {
    warn!(
        operation = "expensive_operation",
        duration_ms = duration.as_millis(),
        "Slow operation detected"
    );
} else {
    debug!(
        operation = "expensive_operation",
        duration_ms = duration.as_millis(),
        "Operation completed"
    );
}
}

This debugging guide provides comprehensive tools and techniques for troubleshooting issues in axiomtrade-rs. Use these patterns to identify and resolve problems efficiently during development and production use.

Frequently Asked Questions

This section covers the most common questions and issues encountered when using axiomtrade-rs.

Authentication & OTP

How to handle OTP timeouts?

Q: My OTP codes are expiring before I can use them. What should I do?

OTP codes from Axiom Trade typically expire within 5 minutes. Here are solutions:

  1. Enable automatic OTP fetching (recommended):

    # Set up inbox.lv credentials
export INBOX_LV_EMAIL="your_username@inbox.lv"
export INBOX_LV_PASSWORD="your_special_imap_password"

  2. Reduce manual entry time:

    • Have your email client open and ready
    • Use email forwarding to a fast email provider
    • Consider using a mobile app for quicker access

  3. Request new OTP if expired:

    #![allow(unused)]
fn main() {
// The client will automatically request a new OTP if the previous one expired
let result = client.login_with_credentials("username", "password").await;
}

  4. Configure timeout settings:

    #![allow(unused)]
fn main() {
let client = EnhancedAxiomClient::new()
    .with_otp_timeout(Duration::from_secs(300)) // 5 minutes
    .build();
}

Why are my tokens expiring?

Q: I keep getting authentication errors even though I just logged in.

Token expiration can occur for several reasons:

  1. Access tokens expire quickly (typically 1 hour):

    #![allow(unused)]
fn main() {
// Enable automatic token refresh
let client = EnhancedAxiomClient::new()
    .with_auto_refresh(true)
    .build();
}

  2. Server-side session invalidation:

    • Multiple logins from different locations
    • Security policy changes
    • Server maintenance

  3. Clock synchronization issues:

    # Ensure system time is synchronized
ntpdate -s pool.ntp.org  # Linux/macOS
w32tm /resync            # Windows

  4. Check token status:

    #![allow(unused)]
fn main() {
if client.is_token_expired().await {
    client.refresh_token().await?;
}
}

Rate Limiting & Performance

How to increase rate limits?

Q: I'm getting rate limited. How can I handle more requests?

Rate limiting is enforced by Axiom Trade's servers. Here's how to optimize:

  1. Use built-in rate limiting:

    #![allow(unused)]
fn main() {
let client = EnhancedAxiomClient::new()
    .with_rate_limit(10, Duration::from_secs(1)) // 10 requests per second
    .build();
}

  2. Implement exponential backoff:

    #![allow(unused)]
fn main() {
let retry_config = RetryConfig::new()
    .with_max_attempts(3)
    .with_exponential_backoff(Duration::from_millis(100));
}

  3. Batch operations when possible:

    #![allow(unused)]
fn main() {
// Instead of individual balance calls
let balances = client.get_batch_balances(&wallet_addresses).await?;
}

  4. Use WebSocket for real-time data:

    #![allow(unused)]
fn main() {
// Reduces HTTP request load
let ws_client = client.create_websocket_connection().await?;
ws_client.subscribe_to_price_updates().await?;
}

  5. Contact Axiom Trade for increased limits:

    • Premium accounts may have higher rate limits
    • Business partnerships can provide dedicated endpoints

WebSocket Issues

WebSocket reconnection strategies

Q: My WebSocket connections keep dropping. How do I handle reconnections?

WebSocket connections can be unstable due to network issues or server maintenance:

  1. Enable automatic reconnection:

    #![allow(unused)]
fn main() {
let ws_client = client
    .websocket()
    .with_auto_reconnect(true)
    .with_ping_interval(Duration::from_secs(30))
    .build()
    .await?;
}

  2. Implement custom reconnection logic:

    #![allow(unused)]
fn main() {
async fn handle_websocket_connection() -> Result<(), AxiomError> {
    let mut retry_count = 0;
    const MAX_RETRIES: u32 = 5;
    
    loop {
        match client.connect_websocket().await {
            Ok(ws) => {
                retry_count = 0; // Reset on successful connection
                handle_messages(ws).await?;
            }
            Err(e) if retry_count < MAX_RETRIES => {
                retry_count += 1;
                let delay = Duration::from_secs(2_u64.pow(retry_count));
                tokio::time::sleep(delay).await;
            }
            Err(e) => return Err(e),
        }
    }
}
}

  3. Monitor connection health:

    #![allow(unused)]
fn main() {
ws_client.on_disconnect(|reason| {
    log::warn!("WebSocket disconnected: {}", reason);
    // Trigger reconnection
});
}

  4. Handle message queuing during disconnection:

    #![allow(unused)]
fn main() {
let (tx, rx) = tokio::sync::mpsc::channel(1000);
// Queue messages when disconnected
// Replay when reconnected
}

Platform-Specific Issues

Windows-specific problems

Q: I'm having issues on Windows. What should I check?

  1. TLS/SSL certificate issues:

    # In Cargo.toml, ensure native-tls feature
[dependencies]
reqwest = { version = "0.11", features = ["native-tls"] }

  2. Firewall and antivirus:

    • Add axiomtrade-rs to firewall exceptions
    • Whitelist in antivirus software
    • Check Windows Defender settings

  3. Path and environment variables:

    # Use double quotes for paths with spaces
set AXIOM_CONFIG_PATH="C:\Users\Username\My Documents\axiom"

  4. Line ending issues:

    git config core.autocrlf true

macOS-specific problems

Q: Having trouble on macOS. Any known issues?

  1. Keychain access for credentials:

    #![allow(unused)]
fn main() {
// Use keychain-rs for secure credential storage
use keychain::Keychain;
let keychain = Keychain::new();
}

  2. Certificate validation:

    # Update certificates
brew install ca-certificates

  3. Permission issues:

    # Ensure proper permissions
sudo chown -R $(whoami) ~/.axiom

Linux-specific problems

Q: Issues running on Linux distributions. What to check?

  1. Missing dependencies:

    # Ubuntu/Debian

# CentOS/RHEL
sudo yum install openssl-devel

# Arch Linux
sudo pacman -S openssl pkg-config

  2. glibc version compatibility:

    # Check glibc version
ldd --version
# May need to compile with older glibc target

  3. SELinux or AppArmor restrictions:

    # Check SELinux status
sestatus
# Configure policies if needed

Environment & Configuration

Environment setup issues

Q: My environment variables aren't being loaded correctly.

  1. Verify .env file location:

    # Should be in project root or specify path
AXIOM_CONFIG_PATH=/path/to/config/.env

  2. Check .env file format:

    # Correct format (no spaces around =)
AXIOM_API_KEY=your_key_here
INBOX_LV_EMAIL=user@inbox.lv

# Incorrect format
AXIOM_API_KEY = your_key_here  # Spaces cause issues

  3. Environment variable precedence:

    #![allow(unused)]
fn main() {
// Order of precedence:
// 1. System environment variables
// 2. .env file in current directory
// 3. .env file in project root
// 4. Default values
}

  4. Permission issues:

    chmod 600 .env  # Secure permissions

Trading & Portfolio

Portfolio balance discrepancies

Q: The balance I see doesn't match what's in my wallet.

  1. Check for pending transactions:

    #![allow(unused)]
fn main() {
let portfolio = client.get_portfolio_with_pending().await?;
}

  2. Network synchronization delays:

    • Solana transactions can take 30-60 seconds to confirm
    • Check transaction status on Solana explorer

  3. Multiple token account addresses:

    #![allow(unused)]
fn main() {
// Get all token accounts for a wallet
let token_accounts = client.get_token_accounts(&wallet_address).await?;
}

  4. Cache invalidation:

    #![allow(unused)]
fn main() {
// Force refresh from blockchain
let fresh_balance = client.get_balance_fresh(&wallet_address).await?;
}

Trading execution failures

Q: My trades are failing to execute. What could be wrong?

  1. Insufficient balance or slippage:

    #![allow(unused)]
fn main() {
let trade_params = TradeParams {
    slippage_tolerance: 0.05, // 5% slippage tolerance
    max_gas_fee: Some(0.01),  // Maximum gas fee in SOL
    ..Default::default()
};
}

  2. Network congestion:

    • Increase gas fees during high congestion
    • Use priority fee estimation

  3. Market conditions:

    • High volatility periods
    • Low liquidity for specific tokens

  4. Wallet connectivity:

    #![allow(unused)]
fn main() {
// Verify wallet connection
let wallet_status = client.check_wallet_connection(&wallet_address).await?;
}

Debugging & Diagnostics

  • Default OTP Wait: 120 seconds
  • Email Check Interval: 5 seconds

Custom Timeout Configuration

#![allow(unused)]
fn main() {
use axiomtrade_rs::client::enhanced_client::EnhancedClient;
use std::time::Duration;

// Create client with custom timeout
let mut client = EnhancedClient::builder()
    .with_timeout(Duration::from_secs(60))
    .build()?;
}

Retry Configuration

Default Retry Settings

  • Maximum Retries: 3 attempts
  • Initial Delay: 100 milliseconds
  • Maximum Delay: 30 seconds
  • Backoff Strategy: Exponential with jitter

Retry Conditions

The following errors trigger automatic retries:

  • Network timeouts

}

Rate Limiting Configuration

Global Rate Limits

  • Default: 300 requests per 60 seconds
  • Sliding Window: 60-second window

Rate Limiting Implementation

The library uses a token bucket algorithm with the following characteristics:

  • Token Refill Rate: Configurable tokens per second
  • Bucket Size: Maximum burst capacity
  • Automatic Backoff: Waits when rate limit is exceeded

Custom Rate Limiting

#![allow(unused)]
fn main() {
use axiomtrade_rs::utils::rate_limiter::RateLimiter;
use std::time::Duration;

// Create custom rate limiter: 100 requests per minute
let rate_limiter = RateLimiter::new(100, Duration::from_secs(60));

// Or use bucket rate limiter
use axiomtrade_rs::utils::rate_limiter::BucketRateLimiter;
let bucket_limiter = BucketRateLimiter::new(100.0, 10.0); // 100 tokens, 10/sec refill
}

Endpoint-Specific Rate Limits

#![allow(unused)]
fn main() {
use axiomtrade_rs::utils::rate_limiter::EndpointRateLimiter;

let endpoint_limiter = EndpointRateLimiter::new();

// Add specific limits for trading endpoints

    Duration::from_secs(60)
).await;
}

        println!("Insufficient balance: {}", msg);
        // Show current balance and suggest funding wallet
        let balance = portfolio_client.get_balance(&wallet_address).await?;
        println!("Current SOL balance: {:.6}", balance.sol_balance);

match trading_client.buy_token(token_mint, amount, Some(1.0)).await {
    Err(AxiomError::Trading(TradingError::SlippageExceeded(msg))) => {
        println!("Slippage exceeded: {}", msg);
        println!("Market is volatile. Try:");
        println!("1. Increase slippage tolerance to 2-5%");
        println!("2. Reduce trade amount");
        println!("3. Wait for market to stabilize");

match market_client.get_trending_tokens().await {
    Err(AxiomError::RateLimit) => {
        println!("Rate limit exceeded. Waiting before retry...");
        tokio::time::sleep(Duration::from_secs(60)).await;
        
        // Retry the request

            Err(e) => println!("Retry failed: {}", e),
        }
    }
    Ok(tokens) => println!("Found {} trending tokens", tokens.len()),
    Err(e) => println!("Request failed: {}", e),
}
}

WebSocket Connection Issues

Scenario: WebSocket disconnection with reconnection

#![allow(unused)]
fn main() {
impl MessageHandler for MyHandler {
    async fn on_disconnected(&self, reason: String) {
        println!("WebSocket disconnected: {}", reason);
        
        // Implement exponential backoff for reconnection
        let mut backoff = Duration::from_secs(1);
        let max_backoff = Duration::from_secs(60);
        
        loop {
            tokio::time::sleep(backoff).await;
            
            match self.ws_client.reconnect().await {

                }
            }
        }
    }
}
}

Error Handling Best Practices

1. Use Result Types Consistently

#![allow(unused)]
fn main() {
// Good: Explicit error handling
pub async fn get_portfolio(&self) -> Result<Portfolio, AxiomError> {
    match self.make_request().await {
        Ok(response) => Ok(response.json().await?),
        Err(e) => Err(AxiomError::Network(e)),
    }
}

// Avoid: Panicking on errors
pub async fn get_portfolio_bad(&self) -> Portfolio {
    self.make_request().await.unwrap().json().await.unwrap()
}
}

2. Implement Retry Logic for Transient Errors

#![allow(unused)]
fn main() {
use crate::utils::retry::{RetryConfig, retry_with_backoff};

let config = RetryConfig {
    max_attempts: 3,
    initial_delay: Duration::from_millis(500),
    max_delay: Duration::from_secs(10),
    backoff_multiplier: 2.0,
};

let result = retry_with_backoff(config, || async {
    market_client.get_trending_tokens().await
}).await;
}

3. Provide Context in Error Messages

#![allow(unused)]
fn main() {
// Good: Contextual error messages
match trading_client.buy_token(mint, amount, slippage).await {
    Err(e) => return Err(AxiomError::Api {
        message: format!("Failed to buy {} tokens of {}: {}", amount, mint, e)
    }),
    Ok(response) => response,
}
}

4. Handle Authentication Errors Gracefully

#![allow(unused)]
fn main() {
async fn handle_auth_error(error: AuthError) -> Result<(), AxiomError> {
    match error {
        AuthError::TokenExpired => {
            println!("Token expired, attempting refresh...");
            // Attempt token refresh
            let token_manager = TokenManager::new(None);
            token_manager.refresh_token().await?;
            Ok(())
        }
        AuthError::Unauthorized => {
            println!("Authentication invalid, please log in again");
            // Clear stored tokens and prompt for re-authentication
            let token_manager = TokenManager::new(None);
            token_manager.clear_tokens().await?;
            Err(AxiomError::Authentication {
                message: "Re-authentication required".to_string()
            })
        }
        _ => Err(AxiomError::Auth(error)),
    }
}
}

5. Validate Input Parameters Early

#![allow(unused)]
fn main() {
fn validate_token_mint(mint: &str) -> Result<(), AxiomError> {
    if mint.is_empty() {
        return Err(AxiomError::Api {
            message: "Token mint cannot be empty".to_string(),
        });
    }
    
    if mint.len() < 32 || mint.len() > 44 {
        return Err(AxiomError::Api {
            message: format!("Invalid mint address length: {}", mint),
        });
    }
    
    if !mint.chars().all(|c| c.is_ascii_alphanumeric()) {
        return Err(AxiomError::Api {

6. Use Structured Logging for Error Tracking

#![allow(unused)]
fn main() {
use tracing::{error, warn, info};

match trading_client.execute_trade(&order).await {
    Ok(result) => {
        info!(
            transaction_signature = %result.signature,
            amount = %order.amount,
            token = %order.token_mint,
            "Trade executed successfully"
        );
    }
    Err(e) => {
        error!(
            error = %e,
            order_id = %order.id,
            token = %order.token_mint,
            "Trade execution failed"
        );
        
        // Log additional context for debugging
        warn!(
            user_balance = %current_balance,
            required_amount = %order.amount,
            "Insufficient balance detected"
        );
    }
}
}

Debugging Error Scenarios

Enable Debug Logging

#![allow(unused)]
fn main() {
// In your application initialization
use tracing_subscriber;

tracing_subscriber::fmt()
    .with_max_level(tracing::Level::DEBUG)
    .init();
}

Common Debugging Commands

# Run with debug output
RUST_LOG=debug cargo run --example basic_login

# Run specific test with detailed errors
cargo test test_authentication -- --nocapture

# Check network connectivity
curl -v https://api6.axiom.trade/health

Error Investigation Checklist

  1. Check Network Connectivity

    • Verify internet connection
    • Test API endpoint accessibility
    • Check firewall settings

  2. Validate Authentication

    • Verify credentials are correct
    • Check token expiration
    • Confirm OTP configuration

  3. Review Request Parameters

    • Validate token addresses
    • Check amount ranges
    • Verify wallet addresses

  4. Monitor Rate Limits

    • Check request frequency
    • Review response headers
    • Implement backoff strategies

  5. Examine Server Status

    • Check Axiom Trade status page
    • Monitor Solana network health
    • Review infrastructure alerts

This reference should help developers quickly identify, understand, and resolve errors when working with the Axiom Trade Rust SDK.

API Endpoints Reference

This document provides a comprehensive reference of all REST API endpoints and WebSocket connections used by the axiomtrade-rs SDK. The Axiom Trade platform uses multiple redundant API servers for load balancing and high availability.

Base URLs and Load Balancing

Primary API Servers

https://api2.axiom.trade
https://api3.axiom.trade
https://api6.axiom.trade
https://api7.axiom.trade
https://api8.axiom.trade
https://api9.axiom.trade
https://api10.axiom.trade

The SDK automatically rotates between these endpoints for load balancing and fault tolerance. Authentication and most trading operations work across all servers.

Specialized Endpoints

  • Main Domain: https://axiom.trade - Used for certain portfolio operations
  • WebSocket Clusters: Various regional endpoints for real-time data
  • External Services: MEV protection and infrastructure monitoring

Security Considerations

Authentication

  • All authenticated endpoints require valid JWT access tokens
  • Tokens expire after 15 minutes and must be refreshed
  • Refresh tokens are valid for 30 days
  • Failed authentication attempts are rate limited

Request Signing

  • Turnkey API requests require P256 ECDSA signatures
  • Signatures include request timestamp to prevent replay attacks
  • Public keys are verified against registered credentials

MEV Protection

  • Transactions are routed through MEV protection services
  • Multiple providers ensure redundancy and optimal routing
  • Real-time monitoring of service health and performance

Data Privacy

  • All API communication uses TLS 1.3
  • Sensitive data is encrypted at rest
  • API logs exclude personally identifiable information
  • Rate limiting prevents abuse and DoS attacks
