How this hook works

Trading tax

A trading tax hook. It takes a cut of every trade.

Takes a cut of every trade

On top of the normal pool fee, it keeps a share of each trade. It can never be above 10%. The fee is paid out in the same trade.

The code that does this (afterSwap):

function _afterSwap(address, PoolKey calldata key, SwapParams calldata params, BalanceDelta delta, bytes calldata)
    internal
    override
    returns (bytes4, int128)
{
    if (params.zeroForOne) return (this.afterSwap.selector, 0);

    int128 ethOut = delta.amount0();
    if (ethOut <= 0) return (this.afterSwap.selector, 0);

    uint256 fee = uint256(uint128(ethOut)) * creatorFeeBps / 10_000;

    poolManager.take(key.currency0, creator, fee);
    emit CreatorFeeTaken(creator, fee);

    return (this.afterSwap.selector, int128(int256(fee)));
}

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

What its code allows

✓Nobody can change its rules after you buyWe read its code and found nothing that lets anyone stop a trade, take funds, or raise what it charges.

Contract1 to review

!Source code not publishedNobody can read what this hook actually does. Treat it as a black box.

✓Code is fixedNo proxy, so the code that runs today is the code that runs tomorrow.

✓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).

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.

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.

✓Won’t reject swapsNo beforeSwap, so trades always reach the pool’s curve.

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.

iKnown template3 other deployments share this exact bytecode, often a launchpad deploying one per token.

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.

Takes a cut when LPs withdraw

It can change what LPs get back when they remove liquidity.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
