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.
Takes a cut when LPs withdraw
It can change what LPs get back when they remove liquidity.
Adjusts deposit amounts
It can adjust token amounts when liquidity is added.
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.
