DTCC announced a new collaboration with Chainlink. The deal places Chainlink’s infrastructure at the center of DTCC’s Collateral AppChain. That platform is a Besu-based blockchain built for tokenized collateral. Additionally, it targets 24/7 near real-time collateral mobility. As a result, market participants gain new tools for managing risk continuously.
DTCC sits at the core of US capital markets. Each year, the company settles trillions of dollars in securities transactions. Therefore, its choice of blockchain vendor carries real weight across the industry. The Chainlink integration also marks a step beyond pilot work. Notably, both firms are now moving toward live production traffic, as confirmed in the official DTCC release.

Inside the Collateral AppChain
The Collateral AppChain tokenizes traditional collateral on blockchain rails. Smart contracts then automate the lifecycle of those assets. As a result, eligibility checks, margining, and settlement happen onchain. Importantly, the system runs continuously rather than during set business hours. This approach removes many of the manual reconciliation steps in legacy workflows.
DTCC first revealed the platform during its Great Collateral Experiment. Now, more than 50 firms have joined the DTC tokenized services working group. DTCC will run a limited live-transaction test in July 2026. Additionally, the company plans a full production launch in October. The rollout positions the platform among the most ambitious institutional blockchain deployments to date.
Chainlink’s Role in the Stack
Chainlink provides the data and orchestration layer for the AppChain. Specifically, DTCC will use the Chainlink Runtime Environment, or CRE. CRE connects onchain systems to legacy infrastructure across multiple chains. Additionally, Chainlink’s data standard unifies how prices, valuations, and movements flow through the platform.
The integration covers a wide set of risk functions. These include pricing, valuation, margin management, optimization, and settlement instructions. Furthermore, Chainlink Data Feeds and Data Streams supply prices for collateral valuation. Sergey Nazarov, Chainlink co-founder, framed the project as a major step. He said the CRE will orchestrate “critical outputs in a secure, private and compliant manner.”
Building on the Smart NAV Pilot
The collaboration extends earlier work between DTCC and Chainlink. In 2024, both companies ran the Smart NAV pilot. That program delivered mutual fund net asset value data onto blockchains using Chainlink’s CCIP. JPMorgan, Franklin Templeton, and BNY Mellon all participated. As a result, the industry saw a working model for tokenizing fund data across multiple chains.
Smart NAV proved that institutions could deliver secure data to public blockchains at scale. The Collateral AppChain takes that foundation further. Now, the goal is not just data delivery, but full collateral lifecycle automation. According to DTCC, the new platform addresses fragmentation across institutions and time zones. Therefore, capital can move where it is needed without long settlement windows.
Processing $2+ quadrillion annually, The Depository Trust and Clearing Corporation (DTCC) is the premier post-trade market infrastructure that provides clearing, settlement, asset servicing, data management, & trade reporting around millions of security transactions each day.

Why TradFi Is Embracing 24/7 Collateral
Traditional collateral systems rely on siloed ledgers and manual reconciliation. Settlement often runs on T+1 or T+2 timelines. In contrast, smart contracts can verify and settle positions in seconds. Additionally, tokenized collateral can move freely across jurisdictions. As a result, banks can pledge the same assets across clearing houses without delay.
Nadine Chakar, DTCC’s global head of digital assets, framed the goal clearly. She said the integration will deliver a unified onchain environment for global markets. Importantly, tokenized real-world assets in the US now sit near $20 billion. That figure continues to grow as more institutions test live deployments. Consequently, demand for shared risk infrastructure keeps rising.
A Signal for the Broader Tokenization Wave
The DTCC and Chainlink deal carries weight beyond the immediate platform. It shows how traditional finance is committing to public-chain-compatible standards. Furthermore, Chainlink is becoming a default oracle and orchestration layer for tokenized real-world assets. Many DeFi protocols already rely on Chainlink for similar functions. Now, the same infrastructure is heading into post-trade workflows for the world’s largest clearinghouse.
Nazarov also called collateral management the killer application that institutional finance has waited for from blockchain. Looking ahead, the October launch will test institutional scale in production. If the rollout meets expectations, similar 24/7 collateral models may spread to other clearinghouses globally. Additionally, the deal strengthens the case that smart contracts can manage real risk in regulated markets. For now, tokenized collateral is moving from pilot phase into production.
