What it does

A small, immutable, unverified hook that runs before each swap, tracks internal counters and can adjust swap amounts by an unknown amount, while LPs can always add and withdraw liquidity freely.

How it works step by step

  • Runs custom logic before every swap in pools that use it.
  • Has the permission to change swap amounts before the swap executes, for example by taking part of the input or supplying output itself.
  • Keeps a few internal counters that are updated on each swap and can be read through a public view function.
  • Has no admin functions and no liquidity callbacks, so LPs are never affected when adding or removing liquidity.
Swap behaviour
Before each swap the hook runs and updates internal counters, and it is allowed to adjust the swap amounts through a return delta. The exact adjustment cannot be confirmed from bytecode alone, and no outbound token-transfer calls were detected.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
Uses the pool's static fee as far as can be seen. Any extra deduction through the swap delta cannot be quantified from the unverified bytecode.
Owner & admin controls
No admin controls found; the only functions are the swap callback and a read-only view.

Enabled Uniswap v4 callbacks

beforeSwap, beforeSwapReturnDelta

beforeSwap: runs custom logic and updates counters before each swap; beforeSwapReturnDelta: lets the hook change the swap's input or output amounts.

Security & trust assessment

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

Who controls it: No privileged keys were found, and the contract is not upgradeable.

Risk to user funds: Only swap amounts can be affected through the before-swap delta, and the size of any effect is unknown from bytecode. LP principal cannot be locked or drained by this hook.

Security findings

  • [low] Unverified swap delta logic: The hook can change swap amounts before execution, but without source code the size or direction of any adjustment cannot be verified.
  • [info] No admin or withdrawal controls: There are no owner functions and no remove-liquidity callbacks, so nobody can block LP withdrawals or change settings.
