BlackRock, which already runs a $2.5 billion tokenized fund called BUIDL, filed with the U.S. Securities and Exchange Commission on July 31 for a new BlackRock Solana fund that will record share ownership directly on Solana, Ethereum and Tempo, TheStreet reported on August 4, 2026.
The filing covers the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle, trading under the ticker RSVXX, a money market fund built to hold cash, short-term Treasuries and overnight repurchase agreements. BlackRock formally introduced the fund this week alongside a second tokenized product, extending a blockchain strategy it began building in 2024.
Where Solana Fits Into the RSVXX Filing
According to TheStreet, the filing lists three networks for recording share ownership: Solana, Ethereum and Tempo. Securitize, the firm that already services BlackRock’s BUIDL fund, will act as RSVXX’s transfer agent, keeping the record of who owns what. The fund is designed to qualify as an eligible reserve asset under the GENIUS Act, the 2025 stablecoin law, meaning issuers could hold RSVXX shares as part of their backing reserves.
CoinDesk reported that U.S. money market funds have grown to more than $8.4 trillion in assets, a figure Jon Steel, BlackRock’s global head of product and platform for cash management, cited as evidence of rising demand. TheStreet noted that BUIDL, BlackRock’s first tokenized fund, is increasingly used across crypto markets as collateral for borrowing and leveraged trading.
What the Solana Filing Means for Institutional Adoption
For Solana, the filing adds another example of institutional infrastructure landing on the network, part of a trend our news coverage has tracked this year. BlackRock has shown the same pattern on Ethereum, where its move to stake $250 million in ETH drew similar attention, testing multiple networks rather than committing to one.
Whether RSVXX Clears SEC Review Before BSTBL Launches
BlackRock has not set a public launch date for RSVXX beyond the July 31 filing, and its start depends on SEC review. Investors tracking Solana’s role in tokenized assets will watch whether RSVXX clears review around the same window as BSTBL, the Ethereum sibling fund CoinDesk reported was filed in May 2026.
What This Means for You
If you hold Solana or follow tokenized funds, this filing signals that a major asset manager sees Solana as reliable enough for institutional money, not just retail trading volume. It does not mean RSVXX is open to individual investors, since the fund targets institutional and stablecoin-issuer clients. Watching how quickly it clears SEC review can offer an early read on how comfortable regulators are with multi-chain fund structures.
