🔒 Security

🛡️ Security Best Practices

• API Key Protection - Never commit .env files 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

🔐 Wallet Configuration Priority

The server uses this priority order for wallet credentials:

1. User-provided private key (in tool parameters)
2. Network-specific private key (from NETWORK_WALLET_PRIVATE_KEY env var)
3. Network-specific mnemonic (from NETWORK_WALLET_MNEMONIC env var)

⚠️ Important Security Notes

• 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
