MarketHoursFeeHook

RobinhoodRegistered

A Uniswap v4 hook that charges a dynamic LP fee based on US equity market session hours. It overrides the LP fee in beforeSwap with a base fee plus a time-varying surcharge (regular, extended, or closed session), routing all fees to LPs via the pool's native tick-crossing accounting. No owner, no admin, no settable state after deployment.
