🔒 Security

  • HTTPS Only - All API calls use HTTPS

  • HMAC Validation - Webhook signature verification with SHA-256

  • Replay Attack Prevention - Nonce caching with 5-minute TTL

  • Data Privacy - Sensitive information is masked in logs

  • No Rate Data - Exchange rates not exposed to prevent inaccuracies

  • Stateless Design - No local persistence, real-time API queries

  • Auto-reconnection - Exponential backoff up to 10 retries for tunnels

  • Health Monitoring - Connection verification every 60 seconds
