BlackRock filed SEC registration amendments on May 8, 2026, to add tokenized money-market fund shares for institutional investors in the United States. One filing names Ethereum-based OnChain Shares for BlackRock Select Treasury Based Liquidity Fund. The move matters because it shows a major asset manager pushing regulated cash products onto blockchain record systems.
The filings do not show that the products are live today. The draft prospectuses say the securities may not be sold until the registration statements become effective. They also state that the SEC has not approved or rejected the securities.
What BlackRock Filed
The first filing covers OnChain Shares of BlackRock Select Treasury Based Liquidity Fund. “Onchain” means ownership and transfer records are handled through a blockchain system.
The filing says these shares will be issued as permissioned ERC-20 tokens on Ethereum. ERC-20 is a common token standard used on Ethereum. Permissioned means only approved users can hold or transfer the shares.
The filing says investors must use wallet addresses that are registered and verified by the transfer agent. Transfers can be restricted, rejected, or frozen under the fund’s rules.
This means the shares are not open public crypto tokens. They are regulated fund shares that use blockchain records.
Fund Details
The fund plans to invest in cash, U.S. Treasury bills, Treasury notes, other Treasury-backed obligations with short maturities, and overnight repurchase agreements backed by Treasury instruments.
The filing lists a $3 million minimum initial investment for institutions. It also says investors may need to pay Ethereum gas fees. Gas fees are payments made to process blockchain transactions.
Second Filing Covers Stablecoin Reserve Fund
BlackRock also filed documents for BlackRock Daily Reinvestment Stablecoin Reserve Vehicle, called BRSRV in the filing. The fund seeks current income while aiming to keep liquidity and principal stability.
The BRSRV filing lists Securitize Transfer Agent, LLC as transfer agent. It says Securitize would maintain official ownership records for OnChain Shares through a permissioned system connected to public blockchains.
The draft does not name the final blockchains for BRSRV. Ethereum is confirmed in the filing for the Select Treasury Based Liquidity Fund, but BRSRV’s final network list is not confirmed.
What the Viral Claim Gets Right
The viral post is partly right. BlackRock did file documents tied to tokenized money-market products. One proposed share class uses Ethereum.
But the filing does not confirm that ETH demand, liquidity, or transaction volume will rise. The team has not officially confirmed this.
BlackRock Already Has BUIDL
BlackRock launched its first tokenized fund, the BlackRock USD Institutional Digital Liquidity Fund, known as BUIDL, on Ethereum in March 2024 through Securitize.
The new filings show BlackRock is expanding its tokenized fund work into money-market products. The products are still traditional fund products at their core. The blockchain layer is used for ownership records, transfer controls, and wallet-based access.
Why This Matters
These filings show that large asset managers are still testing blockchain rails for regulated cash products. For Ethereum, the confirmed impact is infrastructure use by a major financial firm. For stablecoin issuers, the filings point to more regulated reserve options.
For airdrop users, there is no announced token, campaign, or airdrop tied to these filings.
