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.
Handles donations to LPs
It runs when someone donates tokens to the pool’s LPs.
