How this hook works

Token launcher

Pangea lets anyone launch a token. Every trade in a Pangea pool pays an extra fixed fee in ETH or BNB, which goes to the token creator.

Extra fee on every trade

On top of the normal pool fee, each trade pays a fixed fee in ETH or BNB. The token creator’s own first buy is free.

The code that does this (beforeSwap):

function beforeSwap(address sender, PoolKey calldata key, SwapParams calldata params, bytes calldata)
    external
    onlyPoolManager
    returns (bytes4, BeforeSwapDelta, uint24)
{
    // See "NO SWAP RUNS WHILE A FEE IS MOVING": the guard is held by setFee, applyFee, redeem
    // and cancelPendingFee, and by nothing on the swap path.
    if (_reentrancyGuardEntered()) revert SwapDuringFeeChange();
    // Open until this swap's afterSwap (every swap on this hook reaches it: both flags are mined).
    _swapsOpen += 1;
    PoolId id = key.toId();
    Config memory c = configs[id];
    if (!c.registered) revert NotRegistered();
    // The price before this swap, for the token's record in afterSwap (transient: this swap only).
    {
        (uint160 pre,,,) = poolManager.getSlot0(id);
        bytes32 slot = _preSlot(id);
        assembly ("memory-safe") {
            tstore(slot, pre)
        }
    }

    bool exactIn = params.amountSpecified < 0;
    Currency specified = exactIn
        ? (params.zeroForOne ? key.currency0 : key.currency1)
        : (params.zeroForOne ? key.currency1 : key.currency0);
    Currency quote = c.quoteIsCurrency0 ? key.currency0 : key.currency1;

    if (Currency.unwrap(specified) != Currency.unwrap(quote)) {
        return (IHooks.beforeSwap.selector, toBeforeSwapDelta(0, 0), 0);
    // …

The token creator gets paid
Fees build up for each pool, and anyone can trigger the payout to the token creator’s wallet.

Locked-down liquidity

Only approved addresses can add liquidity, so nobody can mess with the launch.

The code that does this (beforeAddLiquidity):

function beforeAddLiquidity(address sender, PoolKey calldata, ModifyLiquidityParams calldata, bytes calldata)
    external
    view
    returns (bytes4)
{
    if (sender != locker && !isLiquidityAdder[sender]) revert OnlyLocker(sender);
    return IHooks.beforeAddLiquidity.selector;
}

Who controls it: The hook developer (Pangea) can approve who adds liquidity and add new launchers. It can’t change the fee or the receiver of a pool that already exists. The code itself can’t be changed.

What do these labels mean? This hook’s code works like PangeaFeeHook (same design, possibly different settings or names), so this is that contract’s description.

✓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).

Pools3 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.

!Can reject swapsIt runs on every trade and can block it. Used for things like launch limits and start times.

!Can take tokens out of swapsIt 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 who can add liquiditybeforeAddLiquidity checks every deposit, so outside LPs may be blocked.

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.

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.

Hook history

Settings changes: set up a new launch (1 time).

Only recent activity is shown: this hook’s past history hasn’t been read yet.

Counted from what the hook recorded on-chain across all its pools, for every action in its published code, plus token transfers in and out of it. Still reading older history, so totals will grow.
