Emergency Stop Functionality

Emergency stop functionality, or circuit breaker, is a feature that allows authorized parties to pause specific contract functions during an active attack. This prevents the further loss of funds by freezing withdrawals, trades, or liquidations until the issue is resolved.

In the context of crypto derivatives, this is essential for managing systemic risk when a vulnerability is discovered or when market volatility threatens to collapse the margin engine. The challenge is ensuring that this power is not abused by developers to rug-pull or censor users.

Effective implementation requires decentralized triggers, such as a multisig or a consensus-based signal from a security council.
