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

Pools3 to review
!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.
iControls who can add liquiditybeforeAddLiquidity checks every deposit, so outside LPs may be blocked.
Track record2 to review
!Not in Uniswap’s hook registryNot listed by Uniswap Labs, so nobody outside the team has looked at it. Most abandoned and malicious hooks are unlisted.
!Brand newIts first pool was created less than a day ago, so it has no track record. Prefer proven hooks for a real launch.
?No audit linkedNothing in the registry. Ask the team for one or review the source yourself.
