BlackRock Launches Stablecoin Reserve Fund BRSRV: Bringing Short-Term U.S. Treasuries to Solana, Ethereum, and Tempo
- Key Insight: BlackRock has launched BRSRV, a tokenized money market fund designed specifically for compliant stablecoin reserves, along with BSTBL on-chain shares — marking its first inclusion of the Solana and Tempo public chains. With a $3 million minimum threshold and a strict whitelist mechanism, this move advances traditional RWA toward institution-grade infrastructure.
- Key Elements:
- Ownership records for BRSRV and BSTBL tokenized shares are maintained on three public chains — Solana, Ethereum, and Tempo — with Securitize serving as transfer agent. Wallets must be whitelisted and bound to verified identities.
- The fund invests entirely in cash, short-term U.S. Treasuries, and overnight repo agreements collateralized by Treasuries, explicitly refraining from investing in any digital assets or virtual currencies.
- The minimum initial investment is $3 million. The structure is designed to meet the qualified stablecoin reserve asset standards under the U.S. GENIUS Act, while noting risks related to regulatory changes and blockchain disruptions.
- BlackRock's BUIDL tokenized money fund, launched in 2024, currently manages over $2.6 billion in assets — this new offering represents an extension of its tokenization strategy.
- Morgan Stanley and Fidelity have also previously launched products for stablecoin reserve management, intensifying industry competition. The announcement emphasizes that traditional finance's "cash hub" is accelerating its move on-chain through multi-chain deployment.

TechFlow Overview: BlackRock, the world's largest asset manager, is putting "money" on-chain. This Monday, BlackRock launched BRSRV, a tokenized money market fund designed specifically for stablecoin reserves, and simultaneously issued on-chain shares of its existing Treasury fund, BSTBL. Unlike previous launches that were only on Ethereum, the ownership records now include Solana and Stripe-affiliated blockchain Tempo, with Securitize serving as transfer agent, wallets requiring whitelisting and KYC binding. The fund invests only in cash, short-term U.S. Treasuries, and overnight repos, explicitly avoiding any crypto assets, with a minimum initial investment of $3 million—it serves as a compliant stablecoin reserve asset under the GENIUS Act and further pushes BlackRock's tokenization narrative, which began with BUIDL in 2024, deeper into institutional waters.
BlackRock Launches Tokenized Money Market Fund for Stablecoin Reserves, Solana Added for the First Time
BlackRock is expanding its business to Solana, launching a money market fund designed specifically for stablecoin reserves and adding the blockchain to its roster of tokenized investment products.
On Monday, the world's largest asset manager introduced the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV) and simultaneously issued tokenized on-chain shares of its existing BlackRock Select Treasury-Based Liquidity Fund (BSTBL).
"Cash remains a foundational building block for investors, corporations, and financial institutions," said Jon Steel, BlackRock's Global Head of Product and Platform for Cash Management, in a statement. "As demand grows for high-quality reserve assets to back stablecoins and other tokenized financial products, these funds provide clients with more options for accessing and utilizing money market fund investment solutions across both traditional and digital markets."
On-Chain Ownership Now on Solana, Ethereum, and Tempo
In a prospectus filed with the U.S. Securities and Exchange Commission (SEC) on Friday, BlackRock stated that ownership records are maintained on Solana, Ethereum, and Tempo — with investors holding shares through approved wallets managed by transfer agent Securitize.
"The Fund issues on-chain shares through a permissioned system that operates in conjunction with one or more public, permissionless blockchains; as of the date of this prospectus, these chains include Ethereum, Tempo, and Solana, and may include other supported networks in the future," BlackRock wrote.
The fund invests exclusively in cash, short-term U.S. Treasury securities, and overnight repurchase agreements collateralized by U.S. Treasuries. BlackRock emphasized that the fund does not invest in any crypto assets.
"The Fund will continue to invest in accordance with Rule 2a-7 under the Investment Company Act of 1940 and the terms of this prospectus," BlackRock wrote. "The Fund will not invest in any digital assets, including any virtual currencies."
$3 Million Minimum Investment, Targeting Compliant Reserves Under the GENIUS Act
Wallets must be whitelisted and linked to verified identities, allowing the transfer agent to restrict transfers or, in certain circumstances, freeze, revoke, or reissue tokenized shares. The fund also carries a $3 million minimum initial investment.
BlackRock said the fund is structured to qualify as an eligible reserve asset under the GENIUS Act (the U.S. law governing payment stablecoins). The prospectus also notes that future regulatory changes could impact whether stablecoin issuers can continue to use the fund as a reserve asset, and that blockchain outages or smart contract defects could also disrupt transactions.
From BUIDL to BRSRV: BlackRock's Tokenization Landscape
The launch builds on BlackRock's broader tokenization strategy. The company launched the tokenized money market fund BUIDL in March 2024, which now manages over $2.6 billion in assets.
Following the passage of the GENIUS Act, BlackRock has joined the ranks of Morgan Stanley and Fidelity, both of which have also launched products for stablecoin reserve management.
Epilogue: When "Shadow Banking" Meets On-Chain Settlement
From BUIDL to BSTBL to BRSRV, BlackRock has, in less than two and a half years, progressively moved money market funds—the "cash hub" of traditional finance—onto the blockchain, expanding from Ethereum to Solana and Tempo. For stablecoin issuers, this means a compliant, transparent, on-chain-settled reserve asset channel is taking shape. For the entire RWA sector, the continued commitment of the asset management giant is pushing "on-chain Treasuries" from proof-of-concept toward institutional-grade infrastructure. When the largest pools of money begin to flow in token form, the underlying plumbing of finance may well be quietly being rewritten.
