CumHook
EthereumRegisteredDynamic fee hook that charges LP fees proportional to cumulative directional price impact. Fees increase when swaps worsen price imbalance and decrease (at half rate) when swaps reduce it, with configurable time-based decay. Pools must be configured with fee bounds, decay window, and illiquidity scale before trading is permitted.
