# Security & Custody (Cobo MPC) Your safety is our priority. LeadFi uses a combination of operational controls and institutional custody. ### MPC with Cobo * LeadFi leverages **Cobo’s MPC wallet infrastructure** to secure operational and reserve keys. * **MPC (Multi-Party Computation)** means transaction approvals require multiple distributed key shards, reducing single-point-of-failure risk compared to single private keys. ### Operational safeguards * **Multi-party approvals** for sensitive actions. * **Cold storage majority**: the vast majority of reserves are stored offline with strict operational policies. * **Withdrawal delay & manual review** for large transactions. * **Principle of least privilege** for operational access. ### User self-custody * You retain control of your EVM and Bitcoin wallets. LeadFi never asks for your seed phrase or private keys. * Always verify you are interacting with the official LeadFi app. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
