Security Notes
The server clearly distinguishes between testnet and mainnet functionalities, explicitly disabling certain DeFi/staking tools on testnets by default to prevent misuse. It uses environment variables for API keys (e.g., PINATA_API_KEY, AI service keys) and strongly warns against exposing or hardcoding private keys, which are passed as parameters but not persistently stored. The code explicitly uses `ethers.js`, a well-audited library, for most blockchain interactions. Potential risks include reliance on external RPC providers (rate limits, reliability) and third-party IPFS/AI services, which are external dependencies rather than inherent code vulnerabilities.
