What it does

A token launchpad hook that owns all pool liquidity and taxes every swap's quote side, with early buyers in the first 60 seconds paying up to 90% and everyone afterward paying a fixed 2.5%, split among a rising price floor, the creator and the protocol.

How it works step by step

• Launches tokens into pools the hook creates and owns, placing the entire token supply as a staircase of one-sided liquidity positions; no outside LPs or donations are allowed.
• Charges a tax on the quote side (ETH or $FOBO) of every swap: 90% at launch, falling linearly to 2.5% over the first 60 seconds, then a flat 2.5% forever.
• After launch, the 2.5% tax is split 60% to a price floor, 24% to the token creator (claimable later) and 16% to the protocol team and partners.
• During the 60-second snipe window, 60% of the tax funds the floor (vesting over 10 minutes) and 40% goes to a buy-and-burn of $FOBO.
• Once per block, before the first swap, the hook raises a quote-backed floor wall that can buy back every circulating token, or buys back and burns tokens with floor money it cannot place.

Swap behaviour

Every swap pays a tax on the quote leg, taken from input or output via return deltas: 90% at the first second after launch, falling linearly to 2.5% at 60 seconds, then 2.5%. Partial fills revert, and the block's first swap also triggers the floor raise or buyback, which needs extra gas but cannot block the swap if it fails.

Liquidity behaviour

Only the hook itself can add liquidity; third-party add-liquidity and donations are refused. Remove-liquidity callbacks are disabled, but the hook owns all positions, so there are no outside LPs to withdraw.

Fee behaviour

Pool LP fee is 0%; a hard-coded tax of 90% decaying to 2.5% over 60 seconds after launch, then 2.5% (1.5% floor, 0.6% creator, 0.4% protocol team and partners via a revenue contract). In the snipe window the split is 60% floor and 40% $FOBO buy-and-burn, with nothing to the creator.

Owner & admin controls

No owner can change tax rates or splits; they are constants. Only the factory can create pools and end the launch discount, and a creator can only change their own payout address and claim their accrued fees.

Enabled Uniswap v4 callbacks

beforeInitialize, beforeAddLiquidity, beforeSwap, afterSwap, beforeDonate, beforeSwapReturnDelta, afterSwapReturnDelta

beforeInitialize: refuses pools not created by the hook; beforeAddLiquidity: refuses outside liquidity; beforeDonate: refuses donations; beforeSwap: runs the per-block floor raise and takes tax when quote is the specified amount; afterSwap: takes tax when quote is the unspecified amount and checks full fills; beforeSwapReturnDelta/afterSwapReturnDelta: deduct the tax from swap amounts.

Security & trust assessment

Risk level: low (verified source, high confidence).

Who controls it: No owner keys; the factory only creates pools and the launch discount, and creators only control their own fee payout address. Neither can alter taxes or move pool liquidity.

Risk to user funds: The hook takes 2.5% of the quote side of each swap, up to 90% during the first 60 seconds after launch. There are no external LPs; the hook-owned liquidity cannot be withdrawn by any admin.

Security findings

• [low] Very high launch tax: Swaps in the first 60 seconds after launch pay up to 90% tax, falling linearly to 2.5%. This is a fixed anti-sniping schedule, not admin-adjustable.
• [info] Fixed rates, no admin: Tax rates and splits are hard-coded constants and the contract is not a proxy, so fees cannot be raised later.
• [info] Hook-owned liquidity: All pool liquidity belongs to the hook and backs a price floor that only moves up; no third-party LP funds are involved.
