"DTCC is the backbone of global capital markets, and integrating their tokenization service with Stellar connects public blockchain networks to regulated market infrastructure." — Denelle Dixon, CEO and Executive Director, Stellar Development Foundation
The Depository Trust & Clearing Corporation (DTCC), the entity that processed $4.7 quadrillion in securities transactions in 2025 and custodies $114 trillion in assets across 150 countries, is building a multichain tokenization infrastructure that spans three separate blockchain networks. In three weeks during May 2026, DTCC announced a Stellar public blockchain integration (May 27), a Chainlink-powered collateral appchain (May 12), and confirmed a July pilot timeline for its Canton Network-based tokenization service (May 4). Each announcement targets a different function — securities settlement, collateral management, and asset issuance — forming a layered blockchain stack underneath Wall Street's largest depository.
The SEC's December 2025 no-action letter authorizes DTC to tokenize Russell 1000 stocks, major index-tracking ETFs, and U.S. Treasury securities for a three-year pilot period. More than 50 firms, including BlackRock, Goldman Sachs, JPMorgan, Circle, and Anchorage, have joined DTCC's industry working group to shape the service. Limited production trades are scheduled for July 2026, with a broader launch in October 2026 and Stellar integration targeted for H1 2027.
This is not a proof-of-concept. It is a production deployment timeline from the monopoly clearinghouse of U.S. equities. The scope, if fully realized, would make tokenized securities a native feature of the existing financial plumbing rather than a parallel system.
DTCC's tokenization strategy does not rely on a single blockchain. Instead, it partitions functions across three networks, each selected for a specific operational role:
| Layer | Blockchain | Function | Launch Target | |-------|-----------|----------|---------------| | Asset Issuance | Canton Network | Tokenize DTC-custodied securities; privacy-preserving permissioned ledger | July 2026 (pilot), October 2026 (production) | | Collateral Management | Chainlink CRE on Hyperledger Besu | 24/7 pricing, margining, collateral optimization, settlement | Q4 2026 | | Public Settlement | Stellar | Connect tokenized assets to public blockchain rails; institutional settlement | H1 2027 |
This multichain design reflects a pragmatic engineering decision. Canton handles the privacy and compliance requirements institutions demand for securities issuance. Chainlink's Runtime Environment (CRE) provides real-time data feeds for collateral workflows. Stellar offers a public blockchain with established institutional usage for cross-border settlement.
"This collaboration represents another step forward in DTCC's efforts to build an open, interoperable digital infrastructure that bridges traditional and digital markets," said Frank La Salla, President and CEO of DTCC.
The foundation for this deployment is the SEC's no-action letter issued on December 11, 2025. The letter authorizes DTC to offer a tokenization service for a defined set of highly liquid assets over a three-year pilot period.
Eligible asset classes:
The authorization carries an important constraint: DTC-tokenized assets retain the same investor protections, entitlements, and safeguards as traditionally held securities. This means the tokens are not new instruments; they are digital representations of existing securities within the DTC custody framework. The underlying clearing and settlement obligations remain unchanged.
The three-year duration gives regulators a defined window to evaluate the service before making permanent decisions. If expanded, the eligible universe could eventually encompass the full scope of DTC-custodied assets — $114 trillion.
DTCC's initial tokenization service runs on the Canton Network, a blockchain platform built by Digital Asset Holdings using the Daml smart contract language. Canton was designed specifically for institutional finance, with native privacy controls that allow counterparties to transact without exposing positions to the broader network.
The partnership, announced in December 2025 alongside the SEC no-action letter, positions DTCC as co-chair of the Canton Foundation alongside Euroclear, the Belgium-based international central securities depository. This governance arrangement gives the two largest securities depositories in the Western financial system direct influence over the network's development.
The Canton integration targets Fed-eligible securities, starting with U.S. Treasuries. A minimum viable product was scheduled for H1 2026, with broader rollout in H2 2026. The July 2026 pilot confirmed in DTCC's May 4 announcement covers initial limited production trades using this infrastructure.
On May 12, DTCC announced that Chainlink would provide the data and orchestration layer for its Collateral AppChain, a Hyperledger Besu-based platform designed to automate collateral management.
The AppChain will handle five core functions using smart contracts:
"By leveraging tokenization and distributed ledger technology to modernize collateral mobility, our goal is to enable 24/7, near real-time collateral management across global markets and blockchains," said Nadine Chakar, DTCC Managing Director and Global Head of Digital Assets.
This builds on the Smart NAV pilot conducted in 2024, during which DTCC and Chainlink tested bringing mutual fund net asset value data onto blockchains with JPMorgan, Franklin Templeton, and BNY Mellon participating. The AppChain represents the production evolution of that pilot.
The target launch is Q4 2026, aligned with the broader tokenization service rollout in October.
The May 27 announcement that DTCC would connect its tokenization service to Stellar marks the first time the clearinghouse has committed to a public blockchain integration for custodied assets.
Stellar was selected based on what DTCC described as institutional suitability. "Stellar's proven track record with institutional assets onchain is an important factor in our evaluation of blockchain networks," Chakar stated, adding that DTC plans to connect to "multiple layer-1 and layer-2 networks."
Stellar's institutional metrics as of Q1 2026:
The Stellar integration is targeted for H1 2027. Unlike the Canton Network (which is permissioned), Stellar is a public blockchain, meaning tokenized DTC assets would be accessible on open infrastructure for the first time. The implications for secondary market liquidity and 24/7 trading are significant, though the precise access controls and compliance mechanisms have not yet been detailed.
DTCC convened more than 50 financial industry firms to participate in its tokenization service development. The group includes a cross-section of traditional finance and crypto-native firms:
Confirmed participants include:
The working group's breadth — spanning asset managers, broker-dealers, custodians, market makers, and digital asset firms — reflects DTCC's intent to build a service that functions within the existing market structure rather than creating a parallel system.
This approach contrasts with many tokenization projects in the digital asset space, which have built standalone platforms disconnected from traditional settlement infrastructure. By embedding tokenization within DTC itself, the service inherits existing participant relationships, custody frameworks, and regulatory oversight.
DTCC is not operating in a vacuum. Several parallel efforts are underway:
The broader tokenized real-world asset market crossed $29 billion in 2026, with tokenized U.S. Treasuries alone reaching $13.4 billion by April 2026 — up from $380 million in 2023. Industry projections from SNS Insider value the asset tokenization market at $3 trillion in 2025, projecting growth to $130.67 trillion by 2035 at a 45.85% CAGR.
DTCC's structural advantage is monopoly position. As the sole central securities depository for U.S. equities, its tokenization service does not need to compete for custody; it already holds the assets. The question is whether its multichain approach executes faster than exchange-operator alternatives.
The economic value proposition of DTCC's tokenization stack operates at three levels:
Settlement efficiency. Current equity settlement in the U.S. operates on a T+1 cycle. Tokenized settlement can compress this to near-real-time, reducing counterparty risk and freeing capital that is otherwise locked during the settlement window. For the $114 trillion in DTC-custodied assets, even marginal improvements in capital efficiency translate to billions in freed collateral.
Collateral mobility. The Chainlink-powered Collateral AppChain enables 24/7 automated collateral transfers across institutions and time zones. In traditional markets, collateral movements are batch-processed during business hours, creating inefficiencies for global firms managing positions across geographies. Smart contract automation eliminates manual reconciliation.
Market access. Public blockchain integration via Stellar creates the possibility of new distribution channels for U.S. securities. This is relevant in a market where Stellar's Q1 2026 payment volume reached $5.5 billion, demonstrating existing institutional flow on the network.
Regulatory durability. The SEC's no-action letter is a three-year authorization, not permanent approval. A change in SEC leadership or policy direction could alter the scope or timeline. The letter does not guarantee expansion to the full DTC asset base.
Interoperability complexity. Running three blockchains simultaneously — Canton (permissioned, Daml-based), Hyperledger Besu (consortium), and Stellar (public) — introduces integration risk. Cross-chain asset movement between these heterogeneous networks requires bridging infrastructure that remains largely untested at institutional scale.
Security surface. The April 2026 Kelp DAO exploit ($292 million lost through a LayerZero bridge vulnerability) demonstrates the risks of cross-chain infrastructure. DTCC's multichain approach inherently creates bridge-like dependencies between networks. The security model for these connections has not been publicly detailed.
Adoption uncertainty. The 50-firm working group signals interest but does not guarantee trading volume. Tokenized securities must demonstrate clear cost or liquidity advantages over existing electronic settlement to justify the infrastructure transition. Early-stage tokenization projects have struggled with thin secondary markets.
Concentration risk. DTCC's monopoly position means that a successful tokenization service would further concentrate U.S. securities infrastructure in a single entity operating across both traditional and blockchain rails.
DTCC's May 2026 announcements represent the most concrete production timeline for institutional securities tokenization to date. The scale is defined: $114 trillion in custodied assets, with a pilot scoped to Russell 1000 stocks, index ETFs, and Treasuries. The timeline is specific: July pilot, October launch, H1 2027 public blockchain. The participants are named: BlackRock, Goldman Sachs, JPMorgan, and 47 others.
What distinguishes this from prior tokenization announcements is the infrastructure position. DTCC does not need to persuade issuers to move assets onto a new platform; the assets are already in DTC custody. The tokenization layer sits on top of existing settlement infrastructure rather than replacing it.
The multichain architecture — Canton for privacy, Chainlink for data, Stellar for public access — reflects a design that prioritizes function-specific optimization over single-chain simplicity. Whether this approach proves more resilient or more fragile than monolithic alternatives will depend on the bridging and interoperability mechanisms that remain undisclosed.
The market is moving from theoretical tokenization projections to production deployment schedules. DTCC's $4.7 quadrillion processing volume gives it a structural position that no other entity in the tokenization space can replicate. The July 2026 pilot will be the first empirical test of whether Wall Street's central plumbing can operate on blockchain rails.
