VolatilityFeeHook

UnichainRegistered

A Uniswap v4 hook that combines two fee mechanisms: a dynamic LP fee set by an owner/operator (via off-chain volatility signals) overriding the pool's swap fee each trade, and an additional protocol fee taken as a percentage of each swap's output amount accumulated as ERC-6909 claims for the hook owner.

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.
