What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Sets its own swap fee

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

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

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.
