Pause Mechanism
A privileged switch that halts core protocol functions in an emergency — a circuit breaker that limits damage from active exploits or bugs.
A pause function (often guarded by a multisig or DAO timelock) lets administrators stop a contract mid-incident — freezing withdrawals, halting new deposits, blocking specific functions. Without one, an active exploit can drain a protocol entirely before governance can intervene.
The trade-off is centralization: anyone who can pause is, in principle, a trusted party. Modern protocols mitigate by separating "guardian" (can pause) from "admin" (can unpause and upgrade), and by sharply scoping what the pause can affect.
