How this hook works

Trading tax

A trading tax hook. It takes 1% of every trade.

Takes 1% of every trade

On top of the normal pool fee, it takes 1% of each trade. The rate is written into the code. The tax is paid out in the same trade.

The code that does this (take):

function _take(address currency, int256 amount) private returns (uint256 tax) {
    tax = (uint256(amount < 0 ? -amount : amount) * TAX_BPS) / 10_000;
    if (tax > 0) POOL_MANAGER.take(currency, recipient, tax);
}

Who controls it: Nobody. The hook has no admin functions, and the code cannot be changed.

What its code allows

iCan change where fees are sent (recipient)The hook developer can change an address the hook pays during a trade. If that payment is in ETH and the new address refuses it, trades would fail.

Pools1 to review

!Pools don’t trade in Uniswap’s app yetIt changes swap amounts or fees, 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.

iRuns before every swapIt runs on every trade and can block it. Used for things like launch limits and start times.

iCan 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.

Track record1 to review

!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.

iNot in Uniswap’s hook registryUniswap Labs keeps a public list of hooks whose code and details they’ve checked. This one isn’t on it yet. That’s normal for new hooks, but it means Uniswap Labs hasn’t checked it.

How grading works

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.

Hook history

Nothing recorded yet.

Counted from token transfers in and out of the hook. Its published code records no actions of its own.
