What it does

This unverified hook likely takes a configurable cut from swaps before they execute, with an unknown rate, while leaving LP deposits and withdrawals untouched.

How it works step by step

  • Runs custom logic before every swap and can change how much the swapper pays or receives using a swap return delta.
  • Calls the PoolManager's take function during swaps, so it can pull tokens out of the swap flow to an address.
  • Keeps a stored value (likely a fee rate or amount) that can be set through an unnamed function, plus counters updated on each swap.
  • Exposes a read-only function that reports its stored values.
  • Does not touch liquidity adds or withdrawals.
Swap behaviour
Before each swap the hook can adjust the swap amounts and take tokens through the PoolManager, which likely works as a fee or skim on the swap. The exact amount and recipient cannot be confirmed from bytecode.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
Likely charges a hook fee on swaps based on a stored value, with tokens taken during the swap, but the exact percentage, cap and recipient cannot be verified from unverified bytecode.
Owner & admin controls
An unnamed function writes the stored value read during swaps, likely a fee parameter; who can call it and any cap are unknown from bytecode.

Enabled Uniswap v4 callbacks

beforeSwap, beforeSwapReturnDelta

beforeSwap: runs custom logic and records data before each swap; beforeSwapReturnDelta: lets the hook change swap amounts and take tokens from the swap.

Security & trust assessment

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

Who controls it: Some caller, likely an owner, can update the stored swap parameter; its maximum cannot be confirmed from bytecode.

Risk to user funds: Swappers' tokens can be deducted during swaps by an unverified amount; LP principal cannot be locked or drained by this hook.

Security findings

  • [medium] Swap amounts can be modified: The hook uses a swap return delta and take to remove tokens during swaps; the size of this deduction is set by a stored value whose cap cannot be verified.
  • [low] Settable parameter with unknown access: A two-argument function updates the stored value used in swaps; caller restrictions and limits are not visible without source.
  • [info] LP withdrawals unaffected: Remove-liquidity callbacks and liquidity return deltas are disabled, so LPs can always withdraw.
