## On-Chain Execution Modules

On-chain Execution Modules are the technical components of a protocol that automatically implement governance decisions without the need for manual intervention. These modules are typically governed by time-locks, which provide a buffer period between the approval of a proposal and its execution, allowing users to exit the protocol if they disagree with the impending changes.

By automating the deployment of code updates or the adjustment of risk parameters, these modules reduce the reliance on centralized administrators and mitigate the risk of human error or malice. They represent a critical layer of protocol physics, ensuring that the consensus reached by the community is faithfully translated into the smart contract state.

This architecture is essential for maintaining trust in automated derivative platforms where parameters must be adjusted rapidly in response to market volatility.
