## Time-Locked Transactions

Time-locked transactions are smart contract operations that can only be executed after a certain time or block height has been reached. This feature is used to prevent rapid, unauthorized movements of assets, providing a "cooling-off" period for security teams to react to suspicious activity.

In the context of derivatives, time locks can be used to delay the execution of large liquidations or governance changes, giving the market time to adjust. They add a layer of deterministic security to protocol operations, ensuring that significant changes are transparent and predictable.

By building time-based constraints into the protocol physics, developers create a safer environment for users and institutional participants.
