BlackRock has filed with the U.S. Securities and Exchange Commission to launch two tokenized money-market products, expanding its push into on-chain short-term debt after the growth of BUIDL. The filings show BlackRock moving deeper into tokenized Treasury infrastructure, with one product tied to an existing $6.1 billion liquidity fund and another built specifically for stablecoin holders.
The move follows demand for BUIDL, BlackRock’s earlier tokenized money-market fund, which has grown to roughly $2.5 billion. That traction gives the firm a proven market signal for on-chain Treasury exposure, especially among investors looking to keep dollar liquidity active without leaving blockchain rails.
BlackRock Extends Tokenization Into Liquidity Funds
The first product is the BlackRock Select Treasury Based Liquidity Fund Digital Share Class, or BSTBL digital class. It would tokenize shares of an existing Treasury liquidity fund holding cash and short-duration U.S. government securities, including Treasury bills and other instruments with maturities of 93 days or less.
BlackRock registered the BSTBL digital class to operate on Ethereum while running alongside the fund’s traditional share classes. That structure would allow a conventional money-market product to gain an on-chain share class without replacing the existing fund architecture.
The second product, the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle, or BRSRV, is designed for crypto wallet users and stablecoin holders. Unlike BSTBL, BRSRV is planned as a multi-chain tokenized money-market vehicle, with interoperability across blockchain networks built into the product design.
BRSRV’s stated yield sources include cash, short-term U.S. Treasuries and overnight repurchase agreements backed by Treasuries. The product is aimed at turning idle stablecoin liquidity into regulated short-duration yield, without requiring users to move funds back into traditional bank deposits.
Stablecoin Liquidity Becomes the Target Market
BlackRock is positioning both products as on-ramps between digital dollars and institutional-grade government debt. The strategic objective is to capture a portion of idle stablecoin balances, a market segment described in filings and reporting as reaching into the hundreds of billions.
The filings also arrive as tokenized real-world assets continue to expand. Industry reporting cited in the material placed the tokenized RWA market near $31 billion since 2025, an increase of about 410%, reinforcing the broader capital shift toward blockchain-based financial instruments.
BlackRock’s tokenized fund suite now has a clearer product ladder. BUIDL provides the existing benchmark, BSTBL would add a digital share class for a traditional Treasury liquidity fund, and BRSRV would create a wallet-native vehicle for stablecoin and crypto users seeking daily reinvestment.
The operational appeal is straightforward: tokenized shares can offer faster settlement, greater collateral mobility and easier integration with on-chain financial workflows. For trading desks and treasury teams, regulated tokenized money-market shares could become usable collateral inside blockchain-based liquidity systems.
Regulatory approval remains the key gating factor. The SEC will determine when and how these products can operate at scale, making regulatory clearance central to BlackRock’s tokenized fund expansion.
The next diligence focus will be custody design, repo counterparty exposure and the relationship between fund rules and smart-contract wrapper mechanics. If approved, these products could accelerate capital rotation from idle stablecoins into regulated Treasury-backed instruments and raise the operating standard for multi-chain tokenized fund deployments.
