TestHook

BNBRegistered

TestHook is a Uniswap v4 hook on BNB Chain. A buy/sell tax hook that deducts a configurable fee (capped at 2% each side) on each swap using Uniswap v4 custom accounting: pulls the fee via poolManager.take() and returns a BeforeSwapDelta so pool accounting nets to zero. Collected fees accumulate in the contract and can be withdrawn only to the immutable owner address.

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.

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.

Safety report

Automated checks, not an audit

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

!Has an adminowner() is 0xa584…4369. That account can usually change fees, limits or allowlists after you trade.

!In Uniswap’s hook registry, not tradeable in Uniswap’s app yetRegistered with Uniswap Labs (a listing, not a security review). 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.Registry Routing rules

✓Source code publishedThe code on the block explorer matches what's deployed.

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