2.4. Interface Only. MetEngine serves solely as an interface to facilitate your interaction with Protocols on the Solana Network. We are not a broker, intermediary, agent, or advisor, and we do not execute transactions on your behalf.

2.5. Third-Party Authentication. MetEngine uses Privy for wallet authentication and user login services. Your use of Privy's services is subject to Privy's Terms of Service. We encourage you to review Privy's terms and privacy policy to understand how they handle your authentication data.
