HookControllerV2

EthereumRegistered

Controls LP fees dynamically (30 bps normal, 300 bps in defensive mode triggered by liquidation cascades), gates new short positions via a pause flag that any caller can toggle by calling the permissionless updateHookState function (which has no access control), and maintains a per-pool tick observation ring buffer for TWAP computation.
