Security Considerations

Important Security Notes:

1. Private Keys: Never commit your AGENT_SECRET_KEY to version control

2. Environment Variables: Use secure secret management for production

3. API Access: Limit MCP server access to trusted AI agents

4. Testnet First: Always test on Somnia Testnet before mainnet operations

Troubleshooting

Build Errors

# Clear all dependencies and rebuild
pnpm clean
rm -rf node_modules pnpm-lock.yaml
pnpm install
pnpm build

Connection Issues

• Verify RPC URLs are accessible

• Check network environment (MAINNET vs TESTNET)

• Ensure correct chain ID configuration

Signing Failures

• Verify AGENT_SECRET_KEY is correctly formatted (0x prefix)

• Check private key has required permissions

• Ensure sufficient balance for gas fees
