BlackRock, the world’s largest asset manager, is moving deeper into blockchain technology with a new regulatory filing aimed at launching tokenized shares of its $150 billion Treasury Trust Fund.
The filing, submitted to the US Securities and Exchange Commission (SEC) on April 29, outlines plans to offer digital shares using distributed ledger technology (DLT), a major step toward integrating blockchain into traditional finance.
The proposed shares will be issued exclusively through BNY Mellon, which will also maintain a parallel digital ledger of share ownership using blockchain infrastructure.

BlackRock’s DLT Shares Aim to Modernize Ownership
BlackRock’s DLT shares, while not involving cryptocurrency investments, are designed to modernize ownership records and transaction processing.
Institutional investors will need to commit a minimum of $3 million for an initial purchase. However, subsequent investments will not carry a minimum requirement.
According to the SEC filing, the fund—formally known as the BlackRock Liquidity Funds Treasury Trust Fund—does not currently use blockchain technology in its operations.
However, BNY Mellon plans to track ownership of the DLT shares using a blockchain mirror record. As of 29 April 2025, the Treasury Trust Fund had assets totaling approximately $150.1 billion. This makes it one of the largest money market funds in the world.
The initiative aligns closely with comments made by BlackRock CEO Larry Fink, who has publicly endorsed tokenization as a transformative force in financial markets.

In his 2025 annual letter to shareholders, Fink wrote that tokenization “will revolutionize investing,” by enabling faster settlement times, reducing market friction, and unlocking capital that is currently tied up in slow-moving processes.
He also emphasized the democratizing potential of tokenization, such as fractional ownership, streamlined shareholder voting, and broader access to yield-bearing assets.
Despite this optimism, Fink acknowledged that identity verification remains a key hurdle before tokenized assets can become mainstream. Still, he believes that tokenized funds will eventually be as common as exchange-traded funds (ETFs).

Financial Giants Jump on Tokenization Trend
BlackRock’s move follows similar efforts by other financial giants including JPMorgan, Franklin Templeton, and State Street, all of which are exploring blockchain to modernize fund operations.
The tokenization trend is rapidly expanding. London-based Calastone recently integrated Fireblocks’ blockchain infrastructure to allow fund managers to tokenize assets on its platform.
Meanwhile, Libre, a blockchain project focused on real-world assets (RWAs), announced plans to tokenize $500 million in Telegram-issued bonds on The Open Network (TON), offering institutional investors decentralized access to the messaging platform’s fixed-income products.
According to RWA.xyz, the market value of tokenized RWAs has surged to $18.9 billion—an 89% increase from the previous year—highlighting growing institutional interest in bringing traditional assets onto the blockchain.
