WHATHook

EthereumRegistered

A single ETH/WHAT pool hook that collects a 3% tax on every swap (buys and sells) and distributes all fees to WHAT token holders. Enforces a per-transaction buy size cap of 500 WHAT for the first 70 buys.

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.

Sets its own swap fee

Pools using it let the hook choose the swap fee instead of a fixed tier.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
