According to Wu Blockchain, Uniswap Labs has announced the launch of a new Hook standard based on v4—Permissioned Pools—designed to provide compliance-focused on-chain enforcement infrastructure for permissioned asset trading in automated market makers (AMMs). Initial partners include Superstate, Securitize, and Dowgo, which integrates the ERC-3643 standard. This standard allows asset issuers to manage whitelists directly at the protocol layer rather than through the front end or off-chain, verifying wallet permissions during every trade or liquidity addition. At the same time, it leverages Uniswap v4's virtual accounting mechanism to ensure the secure storage of underlying permissioned assets, paving the way for tokenized funds, securities, and stocks to access DeFi in a compliant manner. https://www.(wublock123.com)/news/news-65190
