What it does

This is a minimal, unverified hook with no fee or admin logic; it cannot take funds or block withdrawals, but swaps and deposits through it may fail because its enabled callbacks appear unimplemented.

This read was written for the hook 0x68f4…8880 on Robinhood Chain and reused here: the two share a code shape, so constants such as fees, owners and addresses can differ.

How it works step by step

  • Registers beforeAddLiquidity and beforeSwap callbacks, but the decoded bytecode shows no matching standard callback handlers for them.
  • Exposes an isValidSignature function (an ERC-1271 style signature check) and a few unnamed read-only getters.
  • Has no visible admin, fee-setting, or token-moving functions.
  • Because the hook address enables callbacks the contract does not appear to implement, swaps and liquidity adds in pools using it may fail.
Swap behaviour
The beforeSwap callback is enabled, but no matching handler was found in the dispatcher, so swaps in pools attached to this hook would likely revert. It cannot take tokens from swaps because return deltas are disabled.
Liquidity behaviour
The beforeAddLiquidity callback is enabled but appears unimplemented, so adding liquidity would likely revert. Remove-liquidity callbacks are disabled, so the hook can never block withdrawals.
Fee behaviour
Uses the pool's static fee; no fee logic is visible.
Owner & admin controls
No admin controls found.

Enabled Uniswap v4 callbacks

beforeAddLiquidity, beforeSwap

beforeAddLiquidity: runs before deposits, but no handler is found in the bytecode; beforeSwap: runs before swaps, but no handler is found in the bytecode.

Security & trust assessment

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

Who controls it: No owner or privileged roles are visible in the bytecode.

Risk to user funds: The hook cannot deduct swap tokens or LP tokens, and it charges no extra fee. LP withdrawals are never touched by the hook.

Security findings

  • [info] Callbacks appear unimplemented: The dispatcher contains no beforeSwap or beforeAddLiquidity handlers, so pools using this hook would likely be unusable for swaps and deposits.
  • [info] No fund-taking capability: Return deltas and remove-liquidity callbacks are disabled, and no admin or transfer functions are visible.
