BlackRock Brings Blockchain to $150 Billion Treasury Fund

On April 29, 2025, BlackRock quietly submitted paperwork to the SEC that could permanently alter how institutional money moves across the globe. The asset manager is seeking regulatory approval for a new BlackRock DLT share class within its giant $150.1 billion Treasury Trust Fund. This is not a speculative cryptocurrency play. Instead, BlackRock wants its custodial partners to maintain a parallel blockchain ledger to track traditional ownership records, signaling a major shift in Wall Street infrastructure.

The $3 Million Ticket to Digital Recordkeeping

The Treasury Trust Fund holds $150.1 billion in traditional assets, making it one of the largest liquidity pools on the market for corporate clients. According to the SEC Form N-1A filing, this new class demands a steep $3 million minimum initial investment. That high barrier to entry makes it explicitly clear that retail buyers are not the target audience for this technological upgrade.

After that initial buy-in, institutional players can make subsequent purchases with no minimum threshold. The management fee for the newly filed tier sits at an accessible 0.18 percent, keeping it highly competitive with traditional institutional products. This pricing structure shows that BlackRock is not charging a premium for the underlying technology, but rather using it to improve backend efficiency.

Instead of reinventing the financial product itself, the firm is simply updating the administrative plumbing. The fund will still operate strictly under SEC Rule 2a-7, which governs money market funds and ensures the portfolio maintains a stable net asset value. Institutions get the exact same portfolio exposure they have always relied on for cash management, just with a modern database handling the receipts.

No Bitcoin Here, Just Traditional Government Paper

A lot of people hear the word blockchain and immediately assume volatile digital assets are involved in the transaction. BlackRock’s approach is entirely different, as the Treasury Trust Fund keeps 100 percent of its assets in cash and short-term U.S. Treasury bills. There is zero exposure to cryptocurrency or decentralized finance protocols in the actual portfolio holdings.

The technology only exists to change how those reliable investments are tracked on the backend. BNY Mellon will step in to maintain a blockchain mirror ledger alongside conventional book-entry records. This means the official legal record remains the traditional database, but the distributed ledger runs in parallel to provide faster updates and greater clarity for participants.

Eventually we expect there will be a convergence where the best of the old system and the new technology will become fused into a new infrastructure system in finance.

According to Head of Digital Assets Robert Mitchnick, the firm views this technology as a foundational shift rather than a passing trend. This dual-ledger system is a cautious but deliberate step toward modernization. It allows institutional players to interact with tokenized fund mechanics without entirely abandoning the legacy systems that Wall Street relies on for compliance.

Key features of the newly proposed share structure include:

• Parallel digital record of ownership updated continuously
• Ledger maintenance handled exclusively through BNY Mellon
• Requires standard institutional identity verification
• Carries the identical risk profile of the core traditional fund

A Quiet Follow Up to the Billions in BUIDL

BlackRock already manages $2.55 billion in its BUIDL fund, proving that institutional appetite for on-chain products is very real. That project launched in early 2024 and served as a successful pilot program for tokenized money market products on the Ethereum network. Now, the firm is taking the lessons learned from that standalone experiment and applying them to its oldest, most boring traditional products.

The success of that initial fund set the stage for this expansion into the $150 billion Treasury umbrella. In a statement celebrating the fund’s early milestones, Securitize CEO Carlos Domingo noted that tokenized securities are a tangible innovation that proves this market is here to stay. That verified confidence is exactly what pushed asset managers to file post-effective amendments for larger legacy funds.

Company leadership has been telegraphing this transition for over a year. Chairman and CEO Larry Fink previously stated in his annual letter to investors that the tokenization of financial assets is the obvious next step for global markets. He predicted that eventually, every stock and bond will sit on one unified general ledger, eliminating the need for complex reconciliation processes.

Wall Street Crowds the Tokenization Waiting Room

BlackRock is not walking this path alone, as the broader financial sector races to implement similar distributed ledger frameworks. Fidelity recently filed paperwork for an Ethereum-based OnChain share class tailored to its own treasury products. Meanwhile, Franklin Templeton has already tokenized a money market fund that manages roughly $300 million across multiple public networks.

The sheer scale of this transition becomes obvious when looking at the broader tokenized U.S. Treasury market, which reached a total market capitalization of $10.8 billion by early 2026. Financial institutions are tired of slow settlement times and cumbersome reconciliation processes. By placing real-world assets on a blockchain, they unlock instant settlements and programmable features that legacy databases simply cannot support.

Projections suggest this is barely the beginning of the shift. Research indicates that the total market size for tokenized real-world assets could reach $16 trillion by the end of the decade. While the SEC still needs to give the final green light to BlackRock’s April 2025 filing, the collective weight of these industry moves suggests that traditional book-entry systems are living on borrowed time.

This quiet SEC filing might not grab the same headlines as a sudden price spike, but its long-term impact on financial markets is far greater. When the biggest asset manager on the planet decides to rewrite the recordkeeping rules for a staple liquidity fund, the rest of Wall Street has no choice but to follow suit. The gap between legacy finance and modern technology is closing, and the #BlackRock transition to digital ledgers ensures that the future of institutional wealth will be fully structured around #TokenizedAssets.
