## Technical Details
- **Exchange API Integration:** CCXT library for unified exchange access
- **Caching:** In-memory with configurable TTL (30s prices, 60s balances)
- **Rate Limiting:** Per-exchange limits (Binance: 15/s, Coinbase: 8/s, Kraken: 1/s)
- **Error Handling:** Automatic retry with exponential backoff (3 attempts)
- **Security:** Read-only operations, no trading or withdrawal capabilities
## Configuration
Environment variables in `.env`:
```bash
# 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
BALANCE_CACHE_DURATION=60
```
## 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.
