What it does

A small, unverified, non-upgradeable contract that charges no hook fees and cannot touch funds, but whose missing swap and add-liquidity handlers likely make its pools unusable for trading and deposits, while LPs can always withdraw.

How it works step by step

  • Registers beforeAddLiquidity and beforeSwap callbacks, but the decoded bytecode shows no dispatched entry point for either callback.
  • Exposes a signature-check function (isValidSignature) and several read-only getters.
  • Has no visible admin setters, fee logic or token-moving calls.
  • Swap or add-liquidity calls routed through this hook would likely revert, because the callback functions do not appear to exist.
Swap behaviour
The beforeSwap permission is enabled, but no matching handler appears in the decoded functions. Swaps in pools using this hook would likely revert, and no fee or token deduction can be applied.
Liquidity behaviour
The beforeAddLiquidity permission is enabled with no visible handler, so adding liquidity may revert. Remove-liquidity callbacks are disabled, so the hook can never block or charge LP withdrawals.
Fee behaviour
Uses the pool's static fee; no dynamic fee or hook fee logic is visible.
Owner & admin controls
No admin controls found; all decoded functions are view-only.

Enabled Uniswap v4 callbacks

beforeAddLiquidity, beforeSwap

beforeAddLiquidity: would run before deposits, but no handler is visible; beforeSwap: would run before swaps, but no handler is visible.

Security & trust assessment

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

Who controls it: No owner or admin functions were found in the bytecode. The contract is a direct, non-upgradeable deployment.

Risk to user funds: The hook cannot deduct any tokens from swaps or liquidity, so the maximum hook fee is 0%. LP withdrawals are unrestricted because remove-liquidity callbacks are disabled.

Security findings

  • [info] Callbacks appear unimplemented: The address enables beforeAddLiquidity and beforeSwap, but no matching functions were decoded, so pools using this hook are likely unusable for swaps and deposits.
  • [info] No fund-taking capability: Return deltas and remove-liquidity callbacks are disabled and the contract is not a proxy, so it cannot take swap tokens or lock LP withdrawals.
