YoinkFeeHook

RobinhoodRegistered

A launchpad fee hook that charges a market-cap-tiered swap fee (0.80%–1.00%) on every trade in registered pools via afterSwap, splitting proceeds between the platform and the pool creator. Includes a configurable launch-window buy cap (anti-snipe guard) enforced via tx.origin.

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.
