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.
