BlackRock has launched two blockchain-based money market fund offerings intended to be used as stablecoin reserves under the U.S. GENIUS Act. According to both outlets, the funds are structured to qualify as eligible reserve assets for permitted U.S. payment stablecoin issuers, positioning the products as tokenized cash equivalents on public or blockchain infrastructure. The announcements describe the funds as part of BlackRock’s broader expansion of tokenized cash products, focused on providing on-chain reserve support for stablecoin use cases. Both CoinDesk and Cointelegraph state that the key goal is regulatory eligibility under the GENIUS Act, which governs reserve requirements for certain payment stablecoins. The reporting does not indicate changes to the underlying concept of money market funds; instead, it emphasizes the tokenized form and the compliance intent with GENIUS reserve-asset criteria. Details such as specific launch date, minimum investments, custody arrangements, and the precise blockchain or distribution partner are not included in the provided excerpts.
