What Is the Purpose of a ‘SafeGuard’ or ‘Emergency Shutdown’ Module in a DeFi Protocol?
A SafeGuard or Emergency Shutdown module is a pre-programmed, high-authority function designed to halt core protocol operations immediately in the event of a catastrophic exploit, bug, or attack. This mechanism is usually controlled by a multi-signature wallet of trusted community members or a highly-concentrated governance vote, ensuring that a quick, centralized action can prevent total loss of funds.
