LiquidityPenaltyHook

UnichainRegistered

A JIT (Just-in-Time) liquidity protection hook that withholds LP fees when liquidity is added and removed within a configurable block window. Fees collected during rapid add/remove cycles are penalized proportionally and donated to in-range liquidity providers, disincentivizing JIT attacks.
