# Multi-Sig & Timelock
Mind Network has implemented a proxy-based approach for the contracts to minimize the impact of any unforeseen issues.
To further enhance security, all permissions related to contract upgrades and administrative functions are managed by a 48-hour timelock controlled by a 2/3 multi-signature mechanism.
When there is a need for a contract upgrade or administrative configuration, the team initiates the request, and the designated multi-signature signer proposes the desired changes with a 48-hour timelock. During this 48-hour period, users have the option to decide whether they want to continue using the contract or opt out. Once the 48 hours have elapsed, the proposed upgrade or configuration change takes effect on-chain.
