Key Highlights
- BlackRock launched two tokenized cash products, BSTBL and BRSRV, to expand its on-chain money market offerings.
- BSTBL tokenizes an existing Treasury-based liquidity fund on Ethereum, while BRSRV is a new multi-chain fund for digitally native institutions.
- BNY Mellon and Securitize provide tokenization and transfer agent services, with both funds investing in cash, short-term U.S. Treasuries, and Treasury-backed repos.
BlackRock, the world’s largest asset manager, has expanded its cash management offerings by launching two tokenized money market products in collaboration with blockchain infrastructure providers.
According to the official announcement, the on-chain shares of the BlackRock Select Treasury-Based Liquidity Fund (BSTBL) and the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV) represent the firm’s latest step in integrating traditional cash strategies with blockchain technology.
How BlackRock’s new tokenized funds work
According to the company, BSTBL provides a tokenized share class on the Ethereum blockchain for an existing money market fund. BNY Mellon acts as transfer agent and tokenization provider, allowing approved institutional investors to transfer shares between compatible wallets, subject to regulatory requirements.
BRSRV, meanwhile, is a newly established tokenized fund aimed at digitally native institutions. It features daily dividend reinvestment and operates across multiple blockchains. Securitize serves as the transfer agent and tokenization platform for BRSRV.
Both vehicles invest in cash, short-term U.S. Treasuries, and overnight Treasury-backed repurchase agreements. “Cash remains a foundational building block for investors, corporations, and financial institutions,” said Jon Steel, Global Head of Product and Platform for BlackRock’s Cash Management business.
Ethereum’s role in institutional tokenization grows
The choice of Ethereum for BSTBL’s tokenized share class aligns with recent shifts in institutional cryptocurrency exposure. According to blockchain intelligence firm Arkham Intelligence, BlackRock clients net-sold approximately $60 million of the iShares Bitcoin Trust (IBIT) ETF in late July 2026 while purchasing over $20 million in Ethereum-related products.
According to the report, BlackRock’s tracked portfolio held approximately 736,000 BTC, valued at around $47.5 billion, and 2.9 million ETH, worth roughly $5.57 billion. This brought the firm’s combined on-chain cryptocurrency exposure to nearly $53 billion.
While Bitcoin continues to account for the majority of the firm’s crypto holdings, recent differences in BTC and ETH investment flows have drawn attention from market participants.
BlackRock’s latest on-chain cash products could also expand Ethereum’s role in institutional finance. By issuing tokenized money market fund shares on Ethereum, the firm enables institutions to use yield-bearing digital assets within decentralized finance (DeFi) applications and stablecoin-based settlement systems.
Securitize builds on its tokenization push
The move comes just a month after Securitize announced the expansion of its Securitize Tokenized AAA CLO Fund (STAC) to the Solana blockchain. The expansion was supported by a $250 million commitment from Ethena, representing one of the largest single investments in tokenized structured credit products on the Solana network so far.
STAC provides exposure to AAA-rated tranches of collateralized loan obligations (CLOs). These senior tranches are backed by diversified pools of corporate loans and are structured to maintain lower credit risk compared to junior portions of the capital stack.
What could slow wider adoption?
The launch also highlights the operational considerations associated with tokenized money market products. While blockchain-based funds can improve settlement efficiency and interoperability, they also rely on blockchain infrastructure, smart contracts, and tokenization platforms that introduce additional technological and compliance requirements compared with traditional money market funds.
The move also comes as institutional investors continue adjusting their crypto allocations. Although BlackRock’s tokenized products are separate from its ETF offerings, recent shifts in investor flows have renewed attention on how traditional asset managers are expanding their digital asset strategies.
As tokenized financial products gain traction, their long-term adoption is likely to depend on regulatory clarity, operational reliability, and whether they offer measurable advantages over existing cash management solutions.
