What it does

An immutable hook that appears to take a fixed, unverified fee from each swap's output and send it to a hard-coded recipient, while leaving LP deposits and withdrawals untouched.

How it works step by step

  • Runs after every swap in pools that use it.
  • Can take a cut of the swap output and pull it out of the PoolManager to a fixed address, likely tied to WETH.
  • Has no storage and no admin functions, so its behaviour is fixed in code.
  • Does not touch liquidity adds or withdrawals.
Swap behaviour
After each swap, the hook can take part of the swap's output through a return delta and withdraw it from the PoolManager. The exact fee size and recipient cannot be confirmed from bytecode alone.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
An extra swap fee appears to be taken from swap output after the swap and sent to a hard-coded recipient. The percentage is not verifiable from bytecode, and the code has no storage, so it cannot be changed after deployment.
Owner & admin controls
No admin controls found; the contract has no storage and no owner functions.

Enabled Uniswap v4 callbacks

afterSwap, afterSwapReturnDelta

afterSwap: runs logic after each swap; afterSwapReturnDelta: lets the hook take a portion of the swap output.

Security & trust assessment

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

Who controls it: No owner or admin keys were found. The contract is not a proxy, so its logic cannot be changed.

Risk to user funds: Only swap output can be reduced by an unverified but fixed fee amount. LP principal cannot be locked or drained.

Security findings

  • [low] Unverified swap fee via return delta: The hook can deduct tokens from swap output and withdraw them. The exact rate cannot be confirmed without verified source, but it is fixed in immutable code.
  • [info] LP withdrawals unrestricted: Remove-liquidity callbacks are disabled, so the hook can never block or charge LP withdrawals.
