Timelock

A timelock is a contract that enforces a mandatory delay between the moment a privileged action is scheduled and the moment it can be executed. Protocol upgrades, treasury movements and parameter changes are queued in public, and only after the delay — commonly between one and several days — can anyone execute them. The point is not to prevent a harmful change but to make it visible before it takes effect, giving users time to withdraw and the wider community time to object. A timelock with a very short delay, or with an emergency path that bypasses it entirely, offers correspondingly less protection.
