BlackRock has filed with the U.S. Securities and Exchange Commission (SEC) to issue tokenized fund shares on the Solana blockchain. According to an Aug. 3 announcement by Solana, the regulatory filing introduces the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV). This Treasury-backed fund aims to expand the asset manager's cash management strategy by bringing stablecoin reserve assets onchain through a fully regulated structure.

The BRSRV product is specifically designed to qualify as a GENIUS Act asset, establishing a compliant framework for regulated stablecoins. The GENIUS Act, signed into law in 2025, created the first comprehensive U.S. federal regulatory framework for payment stablecoins, requiring issuers to hold high-quality liquid reserves and operate under either federal or state oversight. According to the SEC filing, the fund is structured to issue tokenized shares across multiple networks, specifically Solana, Ethereum, and Tempo. By operating as a multi-chain fund rather than being limited to a single blockchain, the vehicle maximizes its accessibility across public networks.

To execute this strategy, BlackRock has partnered with Securitize, a firm it has previously worked with on other tokenization initiatives. The two previously collaborated on the BlackRock USD Institutional Digital Liquidity Fund (BUIDL), which launched on Ethereum in March 2024 and grew to over $1 billion in assets within months of its debut. Securitize is handling the tokenization process, and Securitize Transfer Agent will be responsible for maintaining ownership records across all supported blockchains.

In addition to BRSRV, BlackRock announced the launch of BSTBL, a separate tokenized fund operating on Ethereum. Together, these two products significantly broaden the firm's tokenized cash management offerings within the digital asset ecosystem. The launches come amid a broader wave of institutional tokenization activity, with firms including Franklin Templeton, Goldman Sachs, and JPMorgan exploring or operating blockchain-based fund infrastructure.

It is important to note that while the fund leverages blockchain infrastructure, it does not purchase cryptocurrency. Instead, the fund's underlying assets consist strictly of cash and short-term U.S. Treasury bills.

BlackRock, which manages approximately $15 trillion in assets, continues to aggressively expand its blockchain-based financial infrastructure. Solana described the launch as a prime institutional use case for tokenized finance, though specific details regarding the total capital expected to enter the vehicle upon launch were not disclosed. This filing also coincides with a period of heightened institutional interest in tokenization across public networks.

At the time of the announcement, Solana (SOL) was trading near $73.97, reflecting a 1.43% increase over the previous 24 hours. The network's daily trading volume reached roughly $1.5 billion, representing a nearly 55% surge from the day prior.
