DropFeeHook

RobinhoodRegistered

Uniswap v4 hook for a DROP/ETH pool that charges a flat 1% ETH fee on every swap. On buys (ETH→DROP), the fee is deducted from ETH input via a beforeSwap delta; on sells (DROP→ETH), it is deducted from ETH output via an afterSwap delta. Exact-output swaps are disabled.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
