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.

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.

Safety report

Automated checks, not an audit

✓Not upgradeableNo proxy pattern found: the code is fixed.

!Has an adminowner() is 0x3cc4…578d. That account can usually change fees, limits or allowlists after you trade.

!Not in Uniswap’s hook registry, not tradeable in Uniswap’s app yetUnregistered hooks get less scrutiny. Most scam hooks are unregistered. It 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.

✓Source code publishedThe code on the block explorer matches what's deployed (contract: BasePerpsAtomicJitHook).

iCan change swap amountsIt has a ReturnDelta permission. Normal for fees and burns, but also how fake-quote hooks steal.
