TipOffFeeHook

RobinhoodRegistered

A Uniswap v4 hook that imposes a fixed 5% fee on all swaps, always collected in ETH (currency0), and forwarded to an immutable fee recipient address. Fees are skimmed in beforeSwap when ETH is the specified currency, or in afterSwap when ETH is the unspecified currency.

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