MonkeyHammerHook

EthereumRegistered

Computes a dynamic LP fee for each swap by measuring price deviation between a Uniswap V2 spot price and an EMA-smoothed reference price, then applying a configurable rational quadratic fee curve. The filtered price is updated via time-weighted cumulative averaging every 15 minutes, with the fee rising as spot price deviates from the filter.
