Malicious hooks in Uniswap v4 pools can reportedly attract decentralized-finance traders by presenting unusually appealing swap quotes to routing aggregators. Once a user’s transaction reaches settlement, however, the hook may change its behavior, meaning the execution can differ from the quote that helped win the route. The issue creates a potential gap between the price shown during route selection and the transaction outcome. CryptoSlate reported that the tactic targets the way aggregators compare available liquidity and choose a pool for a trade. The affected technology is linked to Uniswap v4 hooks, customizable code components that can influence pool behavior. Uniswap (UNI) is among the crypto assets associated with the report. The material does not provide details on specific attacks, losses, affected pools, or a response from Uniswap. Traders and market participants are therefore left with a warning about the risks of relying on attractive quotes when routing trades through hook-enabled liquidity.
