What it does

This launchpad-style hook takes an unverified fee from every swap's output and forwards it to a fee receiver, while LPs can always withdraw freely.

How it works step by step

  • Acts as a launchpad or graduation hook: pools are registered per token, and the hook tracks whether each market has graduated.
  • After each swap it can take a cut of the swap output and forward fees to an external fee receiver contract.
  • Has a public compound function that reinvests collected fees into liquidity, and a collect function that sends accrued fees out.
  • Tracks a principal amount per token, which suggests it manages hook-owned liquidity positions.
Swap behaviour
After every swap the hook may take part of the swap output through a return delta as a fee and forward it to a fee receiver. The exact fee rate is not visible in unverified bytecode.
Liquidity behaviour
No add or remove liquidity callbacks are enabled, so LPs can add and withdraw freely. The hook may manage its own positions through register and compound.
Fee behaviour
A swap fee is taken from swap output after each trade and routed to an external receiver through receiveFees. The fee percentage and any cap cannot be confirmed from bytecode.
Owner & admin controls
No clear owner functions were found. Register, compound and collect are callable functions, but their access rules and limits cannot be confirmed from bytecode.

Enabled Uniswap v4 callbacks

beforeInitialize, afterSwap, afterSwapReturnDelta

beforeInitialize: restricts pool creation to registered markets; afterSwap: runs fee and graduation logic after each trade; afterSwapReturnDelta: lets the hook deduct its fee from the swap output.

Security & trust assessment

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

Who controls it: No obvious owner role was found. Who can register markets or trigger collect and compound is unclear from bytecode.

Risk to user funds: The hook can take an unknown share of each swap's output as a fee. LP principal in the pool cannot be locked by the hook, because the hook never runs on withdrawals.

Security findings

  • [medium] Unverified swap fee via return delta: The hook can deduct tokens from swap output after each trade, but the fee rate and any cap cannot be verified without source code.
  • [info] LP withdrawals unrestricted: Remove-liquidity callbacks are disabled, so the hook can never block or charge LP withdrawals.
  • [info] Not upgradeable: This is a direct contract, not a proxy, so its logic is fixed.
