DTCC launches tokenization service covering approximately $30 trillion in eligible securities

The plumbing of American finance just got a blockchain extension.

On October 28, 2026, the Depository Trust & Clearing Corporation (DTCC) launched its Tokenization Service. Eligible institutions can now create 1:1 blockchain-based “digital twins” of select traditional securities. The eligible pool is worth approximately $30 trillion.

If that number sounds big, it is. It is also only a slice of what DTCC’s subsidiary, the Depository Trust Company (DTC), holds. DTC has over $114 trillion in total assets under custody, so the tokenized door is open, but only partway.

What DTCC actually launched

Think of it as a mirror, not a replacement. The original security stays parked at DTC. A token on a blockchain reflects it exactly, one for one.

The service starts small on instrument count, covering between 25 to 34 liquid instruments. The menu includes selected Russell 1000 equities, major ETFs and US Treasuries.

Each token is 1:1 backed by securities custodied at DTC. The tokens also keep their existing CUSIP identifiers, the nine-character codes that work like a Social Security number for a security. Ownership rights carry over too.

DTC keeps control of the official registry. That means the authoritative record of who owns what stays with the same institution that has always maintained it. Compliance checks and investor protections stay in place throughout the process.

Transfers happen on-chain, but only between registered wallets. There is also a schedule: transfers are only permitted between 2 a.m. and 6 p.m. ET.

The networks and the banks on board

At launch, the service runs on two networks. One is the Canton Network. The other is DTCC’s private Hyperledger Besu network, a permissioned blockchain that DTCC operates itself.

More chains are on the roadmap. DTCC plans to expand to Stellar and Circle’s Arc in 2027. Circle is the company behind the USDC stablecoin, and Arc is its blockchain project, so that planned addition would bring a crypto-native player into the mix.

Over 20 major financial institutions have signed access agreements, including J.P. Morgan, Citi and Fidelity.

Participation, however, is limited to DTCC participants.

How we got here

This launch did not appear out of nowhere. It rests on regulatory permission that arrived nearly a year earlier.

In December 2025, the SEC granted DTCC a no-action letter, authorizing controlled tokenization within defined asset classes.

Then came the test run. In July 2026, DTCC piloted the system with more than 30 firms. That pilot established a framework for secure trades and operational efficiencies before the doors officially opened in October.

What this means for markets and crypto

The pitch is efficiency. Tokenization is designed to deliver quicker settlements and better asset mobility, meaning securities can move between parties and use cases with less friction.

But it is worth being precise about what this is not. DTCC’s service is a controlled extension of existing market infrastructure, not a pivot toward decentralized finance. Transfers are restricted, wallets are registered, hours are fixed, and the registry stays centralized at DTC.

The 2027 expansion plans are the detail to watch. Canton and a private Besu network are both built with institutional permissioning in mind. Stellar and Circle’s Arc come from closer to the crypto world, so their planned integration would test how far DTCC is willing to stretch its rails toward networks with crypto-native roots.

Also worth tracking: how quickly the instrument list grows beyond its initial 25 to 34 names. The gap between approximately $30 trillion in eligible assets and over $114 trillion in total custody leaves plenty of room for expansion, assuming the first phase runs smoothly.

A tokenized twin is only as reliable as the link between the token and the underlying security at DTC. Keeping that registry authoritative across multiple blockchains, while respecting transfer windows and wallet restrictions, is an operational challenge that will get more complex with every network added.
