Contract1 to review
!Upgradeable proxyThe hook developer can swap out the code (currently 0xc228…c859), so the rules of every pool using it can change later.
✓No admin key foundIt has no owner wallet, so the hook developer has no single key to change its rules (as far as the standard check goes).
✓Source code publishedThe code on the block explorer matches what's deployed (contract: OwnedStorageProxy).
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 swapsIt runs on every trade and can block it. Used for things like launch limits and start times.
!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 the swap fee1 of its pools use a dynamic fee the hook sets per trade, so LP income depends on its logic.
Track record2 to review
!Not in Uniswap’s hook registryNot listed by Uniswap Labs, so nobody outside the hook developer 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 hook developer for one or review the source yourself.
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.
Sets its own swap fee
Pools using it let the hook choose the swap fee instead of a fixed tier.
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.
