Configuration

Environment variables in .env:

# Exchange API credentials
BINANCE_API_KEY=your_binance_api_key
BINANCE_API_SECRET=your_binance_secret

COINBASE_API_KEY=your_coinbase_api_key
COINBASE_API_SECRET=your_coinbase_secret

KRAKEN_API_KEY=your_kraken_api_key
KRAKEN_API_SECRET=your_kraken_secret

# Optional settings
MOCK_MODE=false
PRICE_CACHE_DURATION=30

Troubleshooting

"No exchanges initialized"

Check that API keys are correctly set in .env file.

"Failed to initialize [Exchange]"

Verify API key permissions are set to read-only and credentials are correct.

Rate Limiting Errors

The server implements automatic rate limiting and retry logic.

Security

Important Security Practices:

1. Use read-only API keys exclusively
2. Never commit .env file to version control
3. Enable IP whitelisting on exchange API keys (recommended)
4. Rotate API keys periodically
5. Keep dependencies updated

This server cannot execute trades or withdrawals - it only reads portfolio data.
