UruLaunchHook

RobinhoodRegistered

A Uniswap v4 launch hook for the URU token that applies a time-decaying sniper tax (up to 99% at launch, decaying to 0%) on swaps during a configurable window, routing proceeds to a vault. It also tracks URU trading volume per epoch to compute a bounded emission-rate signal.
