0x challenges Uniswap over v4 Hook security

DEX aggregator 0x reported on September 14 that an analysis of 84,163 Uniswap v4 Hooks revealed that only 19.4% are considered safe, while 54.2% are malicious and 26.4% are suspected malicious. 0x alleges that malicious Hooks engage in "quote spoofing" to deceive aggregators. Uniswap founder Hayden Adams responded by stating that malicious actors are an inherent byproduct of permissionless systems and that Uniswap's official API and frontend already filter for vetted Hooks. The debate highlights the tension between the openness of the v4 architecture and the responsibility of aggregators to implement effective security filtering.
