What it does

A tiny, immutable hook that only runs after swaps and adds no fees. All trades pay just the pool's normal fee, and LPs can withdraw freely.

How it works step by step

  • Runs a small piece of code after each swap in pools that use it.
  • Has no storage and no admin functions, so its behaviour cannot be changed.
  • Cannot change swap amounts or charge extra fees, because return-delta permissions are off.
  • Never runs on liquidity changes, so LPs can add and withdraw freely.
Swap behaviour
After each swap the hook's afterSwap callback runs. It cannot alter the amounts traded. Given its tiny size and lack of storage, it most likely just acknowledges the swap or emits an event, though this cannot be fully confirmed without source code.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
Uses the pool's static fee.
Owner & admin controls
No admin controls found.

Enabled Uniswap v4 callbacks

afterSwap

afterSwap: runs after each swap, likely a no-op or event hook, with no ability to take tokens.

Security & trust assessment

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

Who controls it: No owner or admin keys were found. The contract is not upgradeable.

Risk to user funds: The hook cannot deduct anything from swaps and touches no LP funds. It charges no extra fee, and LP withdrawals are unrestricted.

Security findings

  • [info] Minimal immutable hook: The contract is 636 bytes with no storage and only an afterSwap entry point. It is not a proxy and cannot be upgraded.
  • [info] No fund-moving permissions: Return-delta and remove-liquidity permissions are disabled, so the hook cannot take swap tokens or block LP withdrawals.
