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.

!Pools don’t trade in Uniswap’s app yetIt runs code on swaps, so Uniswap’s app only routes it once Uniswap Labs approves it, and it isn’t approved yet. Adding liquidity still works, and other apps can trade it.
!Can reject swapsbeforeSwap runs on every trade and can revert it. Used for launch limits and start times; check when it says no, since holders see a failed trade on the token.
!Can change swap amountsIt has return-delta permissions, so it can take or add tokens in every trade (taxes, fees, burns, custom curves). Check where that value goes and who controls it.
!Can lock liquiditybeforeRemoveLiquidity can refuse withdrawals. Fine as an intended LP lock, a problem if LPs need to exit. Check the unlock conditions.
iControls who can add liquiditybeforeAddLiquidity checks every deposit, so outside LPs may be blocked.
