Time-Lock

A security mechanism that enforces a mandatory delay between proposing a privileged action (such as a program upgrade, treasury withdrawal, or parameter change) and its execution. Time-locks give stakeholders and users a window to review pending actions, detect malicious proposals, and exit the protocol if needed. On Solana, time-locks are typically implemented through multisig programs like Squads or governance frameworks that queue transactions for a configurable delay period before they become executable.
