BlackRock just added more tokenized products to its onchain cash management lineup. The investment giant launched OnChain Shares, tied to its Select Treasury Based Liquidity Fund (BSTBL), plus a new multichain release dubbed the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV).
BlackRock has launched two tokenized money market funds.

What's the Scoop?
- Two providers: BSTBL tokenizes BlackRock's existing $6.2B Select Treasury Based Liquidity Fund as a share class on Ethereum, with BNY Mellon acting as transfer agent and tokenization provider. On the flip side, BRSRV is a new multichain fund aimed at digitally native institutions, with Securitize running transfer agent duties.
- Straightforward holdings: Both funds stick to cash, short-term US Treasuries, and Treasury-backed overnight repo. In other words, it's standard money market exposure, just wrapped onchain.
- Built for GENIUS: Additionally, both funds intend to qualify as eligible reserve assets for permitted U.S. stablecoin issuers, positioning BlackRock to capture reserve business as GENIUS Act-compliant stablecoin supply scales up over time.
- Preview potential: BlackRock's Cash Management arm alone oversees roughly $1.07T, a sliver of the firm's +$15T in total AUM. The size here hints at how much capital could eventually make the jump onchain.
- Not their first rodeo: BSTBL and BRSRV join BUIDL, BlackRock's original tokenized Treasury fund, which has grown past $2.5B and expanded to eight chains since launching with Securitize in 2024.
