PerpetualHook

EthereumRegistered

A Uniswap v4 hook for the PerpetualMeme token launchpad that applies a time-decaying buy fee (starting at 95%, decaying to a 10% floor over blocks) and a fixed 10% sell fee. Fees are collected via afterSwapReturnsDelta, with 80% deposited to the PerpetualMeme contract and 20% sent to a protocol fee address. Pool initialization and liquidity additions are restricted to the PerpetualFactory.

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.
