RhmiFeeHook

RobinhoodRegistered

A Uniswap v4 hook for native ETH/RHMI pools that charges a fixed ETH trade tax (immutable, capped at 4%) on every swap, routing fees directly to a treasury address. Fee collection is split across beforeSwap (ETH-specified swaps) and afterSwap (ETH-unspecified swaps) using return deltas; no owner or admin controls exist.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

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.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
