What it does

An unverified hook that can take a cut from swaps based on an adjustable 'hunt rate' of unknown size, while leaving LP deposits and withdrawals untouched.

How it works step by step

  • Runs a check before every swap and can take a cut of the swap amount using a return delta.
  • Keeps a configurable 'hunt rate' value (a 32-bit number) that likely controls how much or how often it takes from swaps.
  • Keeps a second counter that updates on each swap, likely tracking swaps or timing.
  • Sends taken tokens out of the pool manager to some recipient via take.
Swap behaviour
Before each swap the hook reads its rate and counter and may deduct tokens from the swap through a return delta, sending them out via the pool manager. The exact amount, which swaps are hit, and who receives the tokens cannot be confirmed from bytecode.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
May charge an extra deduction on swaps set by a stored 'hunt rate'. The percentage, its cap, and the recipient are unknown from bytecode.
Owner & admin controls
A function taking a 32-bit value writes the rate setting. Whether it is access-restricted and what its maximum is cannot be determined from bytecode.

Enabled Uniswap v4 callbacks

beforeSwap, beforeSwapReturnDelta

beforeSwap: runs custom logic and updates a counter on each swap; beforeSwapReturnDelta: lets the hook change swap amounts and pull tokens out.

Security & trust assessment

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

Who controls it: Some caller, possibly an owner, can change the rate that likely governs swap deductions; limits are unknown. It cannot touch LP withdrawals.

Risk to user funds: Traders' swap amounts can be partially taken by the hook, with an unknown maximum. LP principal cannot be locked or drained by this hook.

Security findings

  • [medium] Unverified swap deduction: The hook can take tokens from swaps via return delta and the take call, but the size and recipient are not verifiable without source.
  • [medium] Settable rate with unknown cap: A 32-bit rate can be changed by a setter whose access control and upper bound are not visible in the decoded data.
  • [info] LP withdrawals unaffected: Remove-liquidity callbacks are disabled, so the hook can never block or charge LP withdrawals.
