The Depository Trust Company has launched its production tokenization service, bringing blockchain-based representations of DTC-custodied securities into its regulated post-trade infrastructure. According to the official DTCC launch announcement, the DTCC Tokenization Service allows eligible participants to convert conventional securities entitlements into tokenized form and transfer them through registered digital wallets. Twenty DTC Participants have already signed agreements to access the service.
The initial roster includes J.P. Morgan, Citi, Morgan Stanley, UBS, Bank of America, Barclays, BNP Paribas, Fidelity Investments, State Street and Citadel Securities, among others. The service launches with 34 securities available for tokenization, while DTC’s broader SEC authorization covers a larger universe that can include selected Russell 1000 stocks, major-index ETFs and U.S. Treasury bills, notes and bonds.
Digital Twins Remain Anchored to DTC Custody
DTC’s model differs from tokenized products that create synthetic exposure to conventional securities. When an eligible asset is converted, the traditional position is immobilized within DTC and a corresponding tokenized entitlement is created. Each token remains backed 1:1 by securities held at DTC and retains the legal rights, economic interests and investor protections associated with the conventional position.
That architecture was already tested during live tokenized securities transactions involving major financial institutions in July. Participants used tokenized equities and Treasuries across collateral pledges, securities lending, repo, delivery-versus-payment and central-counterparty margin workflows. The October launch turns those controlled production exercises into an ongoing service rather than introducing the technology for the first time.
The initial blockchain infrastructure combines the Canton Network with DTCC’s private Hyperledger Besu environment. Canton had previously been selected for tokenization of DTC-custodied Treasury securities, providing configurable privacy for institutional transactions. DTC-registered wallets can now transfer eligible tokenized positions peer-to-peer around the clock within supported networks, while additional blockchain connections are planned.
$30 Trillion Does Not Represent Launch-Day Tokenization
DTCC’s product page displays approximately $30 trillion in assets under custody alongside the 34 launch securities, but that figure should not be interpreted as $30 trillion already tokenized or immediately circulating through blockchain wallets. DTC itself holds more than $114 trillion in securities overall, and only positions deliberately converted by participating firms become tokenized entitlements.
The regulatory perimeter is also defined. A December 2025 SEC no-action letter authorized DTC to operate the tokenization service for three years under specified conditions. The authorization creates a controlled pathway for tokenizing selected DTC-held assets rather than establishing unrestricted permission to place the entire U.S. securities market on-chain.
Network expansion is already part of that roadmap. Stellar is expected to connect to the service during the first half of 2027, while Circle has said DTC-tokenized assets are planned for Arc later in 2027. Multi-network connectivity can broaden where institutional securities move, but each integration remains subject to DTC’s security, resilience, governance and compliance requirements.
The significant change is therefore operational rather than purely technological. DTC Participants can now convert regulated securities already inside established market infrastructure into 1:1 tokenized representations and move them through approved blockchain environments without severing their existing legal and custody framework. Whether that becomes meaningful market infrastructure will depend on the volume tokenized, participant usage and the extent to which firms deploy those assets for collateral, trading and post-trade workflows.
