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.
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.
