PriceDecayFeeHook

RobinhoodRegisteredLaunch a pool with this hook

A Uniswap v4 hook that charges a sliding swap fee based on how far the pool's current price is from its launch price. The fee starts at a configurable maximum at launch and decays linearly to a base fee as the price moves away, with fees collected as ERC-6909 claims in the quote currency and swept to a configurable recipient via a permissionless `sweep()` call. Fee parameters and recipient are owner-controlled.

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.
