What it does

A launchpad hook that charges every buy and sell a fixed, immutable quote-token fee of 0.30% for the platform plus a 0% to 10% creator fee, while leaving LP withdrawals completely unrestricted.

This read was written for the hook 0x3bfe…a0cc on Robinhood Chain and reused here: the two share a code shape, so constants such as fees, owners and addresses can differ.

How it works step by step

  • Charges a fixed fee on every buy and sell, always taken in the quote token (e.g. WETH): 0.30% to the platform plus a creator fee set at launch (0% to 10%, in whole 1% steps).
  • Credits collected fees to a per-launch ledger, where the platform recipient and the creator (or creator-chosen modules) can later claim them.
  • Runs a fixed set of add-on modules chosen at launch on each swap; these are locked in by code hash and cannot be changed afterwards.
  • Only lets the designated launcher initialize the pool, at a preset starting price, with a 0% LP fee.
Swap behaviour
Each swap pays a quote-token fee of 0.30% plus the creator fee (total 0.30% to 10.30%), taken from the quote side whether you buy or sell; partial fills are rejected and swaps can revert if a launch module fails its check.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
Fixed fee of 0.30% to the platform plus an immutable creator fee of 0% to 10% (set at deployment), for a total of 0.30% to 10.30% of the quote amount; the pool's own LP fee is 0%. Fees are minted as claims to a ledger and claimable by the hard-coded platform address and the creator, with optional creator-allocated shares to modules.
Owner & admin controls
No admin controls found; fee rates, recipients, and modules are fixed at deployment.

Enabled Uniswap v4 callbacks

beforeInitialize, beforeSwap, afterSwap, beforeSwapReturnDelta, afterSwapReturnDelta

beforeInitialize: restricts pool creation to the launcher at the preset price; beforeSwap: runs modules and takes the fee from quote input on exact-quote trades; afterSwap: verifies full fill, records fees, and takes the fee from quote output where needed; beforeSwapReturnDelta/afterSwapReturnDelta: allow the hook to deduct the fee from swap amounts.

Security & trust assessment

Risk level: low, estimated (decoded bytecode, high confidence).

Who controls it: There is no owner; the platform recipient, creator, fee rates, and modules are all fixed at deployment. The worst case is a launch-time module that reverts swaps under its own rules.

Risk to user funds: The hook only deducts the stated quote-token fee of 0.30% to 10.30% per swap and sends it to the ledger for claims. It cannot touch LP principal or block withdrawals.

Security findings

  • [info] Immutable bounded fee: Total swap fee is fixed between 0.30% and 10.30% at deployment and cannot be changed by anyone.
  • [low] Launch modules can block swaps: Modules picked at launch run on every swap and may revert it; they are fixed by code hash and cannot touch platform funds or LP liquidity.
  • [info] LP withdrawals unrestricted: Remove-liquidity callbacks are disabled, so the hook can never block or tax LP withdrawals.
