# Server info
curl http://localhost:8080/info- API Key Protection - Never commit
.envfiles or API keys to version control - Per-Network Wallets - Each network has isolated wallet configuration
- Private Key Security - Private keys never leave your environment, only used for signing
- Environment Variables - All sensitive data stored in environment variables
- Input Validation - All inputs validated before processing
- EIP-712 Signatures - Secure withdrawal signatures following Ethereum standards
- Rate Limiting - Built-in rate limiting prevents API abuse
- Secure Communication - HTTPS for all external API calls
- Error Handling - Errors don't expose sensitive information
The server uses this priority order for wallet credentials:
- User-provided private key (in tool parameters)
- Network-specific private key (from
NETWORK_WALLET_PRIVATE_KEYenv var) - Network-specific mnemonic (from
NETWORK_WALLET_MNEMONICenv var)
- Solana private keys must be in base58 format (NO 0x prefix!)
- EVM private keys must be in hex format WITH 0x prefix
- Keep separate wallets for different networks if needed
- Use hardware wallets or secure key management in production
- Never share your private keys or mnemonics
