DirectionalFeeHook

RobinhoodRegistered

Collects a configurable per-direction fee (in basis points, up to 5%) on each swap's unspecified currency via afterSwap, forwarding proceeds to a per-pool vault. Rates are separately configurable for zeroForOne and oneForZero, take effect after a 5-minute delay, and can be suspended globally by the owner via a pause flag without blocking swaps.

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.
