## Flash Crash Sensitivity

Flash crash sensitivity measures how vulnerable a protocol is to sudden, extreme price drops that occur in a very short timeframe. During a flash crash, liquidity can vanish instantly, causing prices to swing wildly and triggering mass liquidations across the ecosystem.

Protocols with high sensitivity to these events may experience cascading failures, where one liquidation triggers another in a feedback loop. Mitigating this sensitivity involves designing protocols with deep liquidity, robust circuit breakers, and conservative collateralization requirements.

By stress-testing for these scenarios, developers can build systems that remain stable even when the market experiences sudden and severe dislocations. This is a critical aspect of systems risk management in the volatile cryptocurrency domain.
