The Depository Trust & Clearing Corporation (DTCC), the primary securities depository and clearing house in the United States, has launched the first practical testing phase of a new blockchain platform designed to convert traditional stocks and government bonds into digital tokens. Approximately 40 of the world's largest financial institutions and technology providers are participating in these large-scale trials, including industry titans such as Vanguard, JPMorgan Chase, BlackRock, Goldman Sachs, and the New York Stock Exchange.
Real Assets on the Blockchain
Unlike previous simulations in isolated sandboxes, this experiment involves moving real assets held in custody at DTCC onto the blockchain. The resulting tokens function as fully fledged digital twins of traditional stocks and bonds, preserving all investor rights, corporate terms, and dividend payments. The pilot group selected the market's most liquid instruments to test the new digital infrastructure, including shares of Microsoft and Circle Internet Group, the Invesco QQQ Trust tracking the Nasdaq-100 Index, the SPDR S&P 500 ETF Trust, the iShares 0-3 Month Treasury Bond ETF, and various US government bonds.
Testing Core Market Mechanisms
During the trading session, participants divided responsibilities to test core market mechanisms on the blockchain. Citadel Securities and API brokerage platform Alpaca carried out a direct conversion of traditional shares into tokenized positions. Vanguard and broker DriveWealth completed a Delivery-versus-Delivery transaction, instantly exchanging one set of tokenized shares for other digital assets—a process that typically takes several days in the traditional financial system. BNP Paribas and Citadel Securities tested securities lending by locking tokenized assets as collateral against financial obligations directly on the blockchain. JPMorgan tested on-chain instructions by tokenizing part of its holdings in the Invesco QQQ fund for interbank operations, while BlackRock tested the technology for round-the-clock liquidity management across its flagship funds.
Timeline and Future Plans
The current tests will continue until the end of the summer. The official commercial launch of DTCC's tokenization program is scheduled for October 2026, after which any financial institution will be able to convert its portfolios to blockchain-based form through standard infrastructure. The next fundamental stage, planned for the first half of 2027, involves integrating the platform with public blockchains, including the Stellar network, which would directly connect the liquidity of institutional giants with the open crypto market.
