RhmiFeeHook

RobinhoodRegistered

Charges a fixed ETH-side trade tax (immutable basis points, max 4%) on all swaps in native ETH/RHMI pools, sending fees directly to an immutable treasury. Uses return-delta hooks: beforeSwap handles cases where ETH is the specified amount; afterSwap handles cases where ETH is the unspecified amount.

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.
