WhaleTaxHook

A simple, creative Uniswap v4 hook: a dynamic-fee hook that charges a higher fee to large swaps: a swap whose specified amount exceeds one percent of the pool's current liquidity (read from the PoolManager) pays the high fee, others the base fee, both fixed at construction.

NoRoundTripHook

A simple, creative Uniswap v4 hook: a hook that forbids an address from swapping in both directions in the same pool within one block: beforeSwap records the block and direction of the caller's last swap per PoolId and reverts the opposite direction in the same block.

VolumeTierFeeHook

A simple, creative Uniswap v4 hook: a dynamic-fee hook that lowers the fee as a pool gets busier: per PoolId, track swap volume in the current one-hour bucket (input amount in the pool's currency0 or currency1, by direction), and charge 30 bps below 100 units, 20 bps below 1000, 10 bps above; the bucket resets each hour.

FirstSwapOfDayHook

A simple, creative Uniswap v4 hook: a dynamic-fee hook where the first swap of each UTC day in a pool pays zero LP fee and every later swap that day pays the pool's base fee set at construction.
