  }
}

This endpoint creates a simulated payment that automatically confirms after 2 seconds, allowing you to test the complete payment flow without real cryptocurrency.

All admin endpoints require Hive authentication headers:

x-account: your-hive-username
x-challenge: unix-timestamp
x-pubkey: your-public-key
x-signature: signed-challenge

GET /api/onboarding/admin/channels?limit=50&status=pending&crypto_type=SOL

GET /api/onboarding/admin/crypto-addresses?cryptoType=BTC&limit=100

GET /api/onboarding/admin/consolidation-info/{cryptoType}
POST /api/onboarding/admin/generate-consolidation-tx

1. Get Pricing: Client calls /pricing to get current rates
2. Initiate Payment: Client submits username, crypto type, and Hive public keys
3. Unique Address: System generates unique payment address
4. Send Payment: User sends exact amount to provided address
5. Monitor: System automatically monitors for incoming transactions
6. Verify: After required confirmations, payment is verified
7. Create Account: Hive account is automatically created with provided keys

• Unique Addresses: Each payment gets its own address
• Rate Limiting: API calls are rate-limited by IP
• Address Reuse: Secure reuse of addresses after 1 week
• Transaction Verification: Multiple verification layers
• Encrypted Storage: Private keys are encrypted in database
• Time Expiration: Payments expire after 24 hours
• Upstream Rate Limiting: Rate limiting handled at proxy/CDN level

Each cryptocurrency is configured with:

• Network endpoints
• Fee estimation
• Block confirmation requirements
• Address generation parameters

Rate limiting has been removed from the application and is now handled upstream at the proxy/CDN level for better performance and scalability.

The system includes comprehensive monitoring:

• Real-time pricing updates (hourly)
• Payment channel monitoring
• Resource credit tracking
• Failed transaction alerts
• System health checks

1. Circular Dependency: The crypto address generator has a circular dependency with the main onboarding module, preventing real address generation. Use the simulation endpoint for testing.

2. Address Generation: Real crypto address generation currently fails due to database connection issues in the crypto generator module.

1. Payment not detected: Check transaction hash and confirmations
2. Address generation fails: Verify CRYPTO_MASTER_SEED is set
3. Pricing unavailable: Check CoinGecko API connectivity
4. Account creation fails: Verify Hive RPC connectivity and RC balance

Use /debug/system-status to check all system components:

curl https://your-domain.com/api/onboarding/debug/system-status

While the real crypto address generation has issues, you can test the complete payment flow using the simulation endpoint:

# Test SOL payment (low fees)
curl -X POST "https://data.dlux.io/api/onboarding/test/simulate-payment" \
  -H "Content-Type: application/json" \
  -d '{"username": "testuser123", "cryptoType": "SOL"}'

# Test BTC payment (high fees)  
curl -X POST "https://data.dlux.io/api/onboarding/test/simulate-payment" \
  -H "Content-Type: application/json" \
  -d '{"username": "btcuser123", "cryptoType": "BTC"}'

# Check payment status
curl "https://data.dlux.io/api/onboarding/payment/status/{channelId}"

• Private Key Encryption: All private keys are now encrypted using AES-256-CBC before database storage
• Rate Limiting Removal: Application-level rate limiting removed for better performance (handled upstream)
• Environment Key Management: Proper encryption key management with environment variables

• Blockchain Monitoring: Real-time monitoring of all supported blockchain networks for payment detection
• Automatic Account Creation: HIVE accounts are automatically created after payment confirmation
• WebSocket Notifications: Real-time status updates for payment progress and account creation

• System Integration Tests: Comprehensive testing of all components working together
• Encryption Testing: Automated validation of private key encryption/decryption
• Blockchain Status Monitoring: Health checks for all blockchain monitoring services

• /api/onboarding/test/system-integration - Complete system health and feature validation
• /api/onboarding/test/encryption - Private key encryption testing
• /api/onboarding/test/blockchain-monitoring - Blockchain monitoring status

• Node.js: 18+ with crypto modules
• PostgreSQL: 13+ for data storage
• Redis: Optional for caching
• Docker: For containerized deployment
