UniHooks

LiquidHookStaticFeeV2

BaseRegistered

A Uniswap v4 hook that applies separate static LP fee tiers for the "liquid" token and the paired token, with a 20% protocol fee extracted from each swap via beforeSwap/afterSwap return deltas. Supports an optional MEV module that can temporarily raise fees during pool launch and optional pool extension callbacks for custom post-swap logic.

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.
