TipOffFeeHook

RobinhoodRegistered

A fixed-rate fee hook for a $TIPOFF/ETH pool that collects a 5% fee on both buys and sells, always denominated in ETH (currency0). Fees are forwarded to an immutable feeRecipient address via return deltas split between beforeSwap (when ETH is the specified currency) and afterSwap (when ETH is the unspecified currency).
