DescendingFeeHook

RobinhoodRegisteredLaunch a pool with this hook

Anti-snipe descending swap fee hook that charges a high fee (up to 99%) at pool launch, holds it briefly, then parabolically decays to a creator-set terminal rate; fees are collected as ERC-6909 claims in the PoolManager and released to the launcher via collect(). LP fee is always static zero.

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.

Handles donations to LPs

It runs when someone donates tokens to the pool’s LPs.
