Wu learned that Uniswap announced in a tweet that Groma is using the Permissioned Pools Hook to launch permissioned assets on Uniswap’s automated market maker (AMM), and to connect the issuance and redemption of real estate assets directly to the protocol. Uniswap said the mechanism enforces compliance checks at the protocol level; Groma’s tokenized securities are available only to U.S. accredited investors and users outside the United States.
