What it can do

Runs on every swap

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

Can change what you receive

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Can block withdrawals

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

Can take a cut on withdrawal

It can change what LPs get back when they remove liquidity.

Controls who can add liquidity

It checks every deposit before it goes in.

Can change deposits

It can adjust token amounts when liquidity is added.

Checks new pools

It runs when a pool is created, often to lock in that pool’s settings.

Handles LP donations

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