GweiTaxHook

EthereumRegistered

A singleton hook for pools launched by GweiFunLaunchpad that charges a time-decaying ETH swap tax (up to 50% max, monotonically decreasing) on buys and sells. Fees are collected via v4 delta accounting and forwarded to the token's deployer, with a configurable max-buy cap during an initial time window.

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.
