What it does

A launchpad hook that charges every buy and sell the same fixed 1% fee and splits it among the treasury, creator, holder rewards, a token burn, and permanently locked liquidity, while third-party LPs keep full freedom to add and withdraw.

How it works step by step

  • Charges a fixed 1% fee on every buy and sell in Integral launch pools, which have a 0% LP fee.
  • Splits the fee per launch between the protocol treasury, the token creator, token holder rewards, a token burn, and auto-added liquidity, using shares fixed at launch in a write-once registry.
  • The burn share is taken in the launched token and burned. All other shares are taken in the base currency and paid out or held as claims on the PoolManager.
  • The liquidity share is added back to the pool as a permanently locked position owned by the dead address once it is large enough (at least 1% of active liquidity).
  • Token holders can claim their accumulated rewards at any time, and creator and treasury payouts can be triggered by anyone.
Swap behaviour
Every swap pays a 1% fee, taken partly from the input and partly from the output, with the burn portion in the launched token and the rest in the base currency. Trading is never paused or restricted, and failed payouts never revert the swap.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely. The hook itself adds fee-funded liquidity as positions locked forever under the dead address.
Fee behaviour
A fixed 1% fee on every trade, hard-coded and unchangeable. It is split by per-launch shares set at launch among the treasury, creator, holders, burn, and auto-liquidity; the pool's LP fee is 0%.
Owner & admin controls
The factory can only change the treasury address that receives the treasury share. The fee rate and per-pool splits are immutable.

Enabled Uniswap v4 callbacks

beforeInitialize, beforeSwap, afterSwap, beforeSwapReturnDelta, afterSwapReturnDelta

beforeInitialize: only the factory may create pools, and they must have a zero LP fee; beforeSwap: loads the pool config and charges the fee on the specified amount; afterSwap: charges the fee on the other side and distributes it to the buckets; beforeSwapReturnDelta/afterSwapReturnDelta: let the hook collect the 1% fee from swap amounts.

Security & trust assessment

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

Who controls it: The factory, which is a proxy contract, can only update the treasury address. It cannot change fees, splits, or trading access.

Risk to user funds: The hook takes exactly 1% of each swap and holds the undistributed base fees as PoolManager claims until they are paid out. It cannot touch or lock third-party LP principal.

Security findings

  • [info] Fixed 1% fee: The fee is a hard-coded constant of 1%, and the splits are write-once registry records that cannot be changed after launch.
  • [info] Treasury recipient changeable: The factory can redirect the treasury share, including any pending treasury balance, to a new non-zero address.
  • [info] LP withdrawals unrestricted: The remove-liquidity callbacks are disabled, so the hook cannot block or charge LP withdrawals. Only the protocol's own fee-funded positions are permanently locked.
