The world's largest asset manager has released two blockchain-based funds designed to serve as backing for regulated US stablecoins.

BlackRock has introduced two tokenized money market products to serve as reserve assets for stablecoins under the US GENIUS Act, a federal stablecoin law enacted in July 2025.

The first product, BlackRock Select Treasury Based Liquidity Fund OnChain Shares (BSTBL), is a tokenized share class of BlackRock's existing Select Treasury Based Liquidity Fund deployed on Ethereum. Eligible investors can transfer shares between approved wallets while the fund invests in cash, short-term US Treasurys and overnight repurchase agreements backed by Treasurys. BNY Mellon serves as the transfer agent and tokenization provider.

The second product, BlackRock Daily Reinvestment Stablecoin Reserve Vehicle (BRSRV), is a newly created tokenized money market fund for institutional investors. It operates across multiple blockchains, automatically reinvests daily dividends and targets digital asset use cases including stablecoin reserve management. Securitize handles the transfer agent and tokenization functions.

Both funds are structured to qualify as eligible reserve assets for permitted US payment stablecoin issuers. The launch expands BlackRock's position in tokenized Treasurys, where its USD Institutional Digital Liquidity Fund (BUIDL) remains the sector's largest with more than $2.6 billion in assets.

These two are not the same thing, and one does not produce the other. The left is how this single article reads, from its tone alone. The right is the site’s own call on the asset, from indicators and analysis. Press tone feeds no score and no signal: on the only corpus this site has measured, daily tone tracked the move that had already happened and showed no measurable link with what followed.
