Uniswap launched its Permissioned Pools Hook, a new protocol-level standard that enforces compliance checks directly within the automated market maker. The first permissioned asset to go live under this framework is Groma, which uses the hook to connect real estate issuance and redemption into Uniswap's infrastructure. Groma's tokenized securities are restricted to U.S. accredited investors and users outside the United States, marking a significant step toward integrating regulated financial instruments into decentralized trading environments while maintaining regulatory compliance at the smart contract level.
