BlackRock Deepens DeFi Footprint with Launch of BSTBL and BRSRV Tokenized Funds

Written by Helena Markou

The convergence of traditional finance (TradFi) and decentralized finance (DeFi) accelerated significantly this week as BlackRock, the world’s largest asset manager, announced the launch of two new tokenized money market products: BSTBL and BRSRV. This expansion of BlackRock’s on-chain strategy highlights a growing institutional appetite for blockchain-based financial infrastructure and specifically targets the rapidly evolving stablecoin ecosystem.

The newly launched funds are designed to combine the regulatory stability and liquidity of traditional money market funds with the operational efficiencies of blockchain technology. The BlackRock Select Treasury Based Liquidity Fund (BSTBL) introduces a tokenized share class of an existing money market fund on the Ethereum blockchain. BNY Mellon serves as the transfer agent and tokenization provider for BSTBL, which allows the “OnChain Shares” to be transferred between approved investor wallets.

Concurrently, BlackRock introduced the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV). Unlike BSTBL, BRSRV is a newly created fund specifically engineered for digitally native institutional investors. It features daily dividend reinvestment and multi-blockchain accessibility, utilizing both Ethereum and Solana. Securitize acts as the transfer agent for BRSRV.

Both BSTBL and BRSRV are mandated to invest exclusively in cash, short-term U.S. Treasury securities, and overnight repurchase agreements backed by U.S. Treasuries. Crucially, the investment strategy for both funds is explicitly designed to qualify them as “eligible reserve assets” for permitted U.S. payment stablecoin issuers under the Guiding and Establishing National Innovation for U.S. Stablecoins Act (the “GENIUS Act”).

This strategic positioning is highly significant. By tailoring these products to meet the stringent reserve requirements of the GENIUS Act, BlackRock is directly targeting the multi-billion-dollar stablecoin industry. Stablecoin issuers require massive, highly liquid, and secure reserves to back their digital tokens. BlackRock is offering a solution that provides the necessary regulatory compliance and yield generation, while operating natively on the blockchain rails that stablecoin issuers already utilize.

“As demand grows for high-quality reserve assets to support stablecoins and other tokenized financial products, these funds provide clients with additional choice in how they access and use money market fund investment solutions across traditional and digital markets,” stated Jon Steel, Global Head of Product and Platform for BlackRock’s Cash Management business.

These launches build upon the success of BlackRock’s initial foray into tokenized funds, the USD Institutional Digital Liquidity Fund (BUIDL), which launched in 2024 and has since grown to over $2 billion in assets under management. The introduction of BSTBL and BRSRV demonstrates that BlackRock views tokenization not as an experimental pilot, but as a core component of its future cash management strategy.

By deploying these assets across major networks like Ethereum and Solana, BlackRock is injecting institutional-grade, yield-bearing collateral directly into the DeFi ecosystem. This move bridges the gap between the $8.4 trillion U.S. money market sector and the digital asset economy, providing a compliant pathway for massive capital inflows into on-chain environments.
