ClankerHookStaticFee

EthereumRegistered

A Uniswap v4 hook for Clanker token pools that enforces separate configurable static LP fees for buying vs. selling the Clanker token, collects a 20% protocol fee on each swap via beforeSwap/afterSwap delta returns, and activates an optional MEV-protection module during the first 2 minutes after pool creation.

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.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

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