The Depository Trust & Clearing Corporation is about to move a large slice of U.S. market infrastructure onto blockchain rails without changing who keeps the official books. Its Tokenization Service, set for a commercial launch in October 2026, converts securities already held at The Depository Trust Company into 1:1 tokenized digital twins that carry the same CUSIP, ownership rights and investor protections as the underlying book-entry assets.

The scope is large. DTCC says roughly $30 trillion in assets are eligible for tokenization, with 25 specific securities available at launch across Russell 1000 large-cap equities, exchange-traded funds and U.S. Treasuries. Because every token is backed by the security sitting at DTC, a tokenized share represents an existing position rather than a newly issued instrument.

What changes is movement and access, not the record of ownership. Participants submit conversion orders through a user interface or API between 2 a.m. and 6 p.m. Eastern time on business days, with processing targeted at 15 minutes or less. Once converted, tokens can move peer-to-peer between DTC-registered wallets around the clock while the official books and records stay with DTC. Because a token carries the same CUSIP as the underlying security, it can serve as collateral or settle against the same entitlements as a traditional position.

The multi-network design matters because it determines where tokenized collateral can travel and which counterparties can accept it. The service launches on the Canton Network using the CIP-56 token standard, and on DTCC’s private Besu network using ERC-20. Stellar (SEP-41) and Circle’s Arc (ERC-20) are expected in 2027, with additional layer-1 and layer-2 networks to follow based on client demand.

Compliance is built in rather than added later. DTCC says its smart contracts launch with mint, burn, pause and clawback functions, plus ComposerX LedgerScan for near-real-time ownership tracking across traditional and blockchain ledgers. On-chain U.S. Treasury servicing, with distributions and maturities paid in fiat to participants’ traditional accounts, arrives at launch.

The rollout follows a December 2025 no-action letter in which the Securities and Exchange Commission’s Division of Trading and Markets addressed DTC’s tokenization program under the Exchange Act. DTCC’s launch materials describe the roadmap as subject to that letter. The technology had already been validated in July 2026, when more than 30 firms processed real trades using DTC-tokenized assets.

It is worth being precise about what the service does not do. It does not issue new securities, does not move official records off DTC’s ledger, and is not open to retail investors; transfers are limited to DTC-registered participant wallets. Tokenization here is a representation layer rather than a transfer of custody away from DTC. On-chain net settlement, digital cash and expanded corporate-action servicing sit on the 2027 roadmap, alongside single sign-on and maker-checker controls.

For an industry that has spent years debating how tokenization should meet regulated market structure, the launch tests a specific proposition: that a token can add 24/7 transferability and programmability on top of existing custody and settlement rails without displacing the central ledger that underpins most U.S. equities today.
