What it does

This unverified, test-like hook runs before every swap and can change swap amounts and take tokens from traders by an unknown amount, while LPs can always add and withdraw liquidity freely.

How it works step by step

  • Runs custom code before every swap in pools that use it.
  • Can change the swap amounts through a return delta and pull tokens out of the PoolManager with a take call.
  • Keeps one counter in storage that is updated on each swap and can be read publicly (a function named buggy()).
  • Looks like a small test or experimental hook rather than a production product.
Swap behaviour
Before each swap the hook runs, updates a stored counter, and may return a delta that changes what the trader pays or receives, taking tokens from the PoolManager. How much it takes cannot be confirmed from bytecode alone.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
No fee percentage could be confirmed. The hook can take part of a swap's tokens through its return delta and take call, but the amount and the recipient are unknown from bytecode.
Owner & admin controls
No admin controls found. No owner or setter functions are visible in the dispatched selectors.

Enabled Uniswap v4 callbacks

beforeSwap, beforeSwapReturnDelta

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

Security & trust assessment

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

Who controls it: No admin or owner functions were found and the contract is not a proxy. Its behaviour appears fixed at deployment.

Risk to user funds: Traders' swap amounts can be altered or partly taken through the before-swap delta, and the exact amount is unknown. LP principal cannot be locked or charged on withdrawal.

Security findings

  • [medium] Unverified swap delta with token taking: The hook can change swap amounts and calls take to move tokens out of the PoolManager. Without source code, the exact amount taken from traders cannot be verified.
  • [low] Experimental-looking contract: The contract is small, keeps a counter, and exposes a function named buggy(). This suggests a test hook that may behave unexpectedly.
  • [info] LP withdrawals unrestricted: The remove-liquidity callbacks are disabled in the hook address, so the hook can never block or charge LP withdrawals.
