0x636cc41a47f6ae8a4543ab8cd31b6efe0320e0ecBlockscoutA Uniswap v4 hook that charges a descending anti-snipe fee: starting at a high rate (up to 99%) held briefly after launch, then parabolically decaying to a configured steady-state rate. The fee is taken in the input currency via hook deltas and accrued as ERC-6909 claims in the PoolManager, collectible by the launcher. LP fee is always zero; donations are disabled.
