The Depository Trust and Clearing Corporation (DTCC) has partnered with Chainlink to bring its Collateral AppChain platform to life. This system will leverage Chainlink’s Runtime Environment and data standard to automate key processes like pricing, valuation, margin calculations, collateral optimization, and settlement around the clock. The service is scheduled to go live in the fourth quarter of 2026.
Nadine Chakar, DTCC’s managing director and global head of digital assets, explained that the initiative aims to modernize collateral management through tokenization and distributed ledger technology, facilitating near real-time movement of collateral across various global markets and blockchain networks. In 2025, DTCC managed a staggering $4.7 quadrillion in securities transactions.
The Collateral AppChain works by tokenizing collateral and employing smart contracts to streamline workflows among different parties, including collateral providers, receivers, managers, triparty agents, and custodians. All of this happens on a shared and interoperable infrastructure. Chainlink serves as the data and orchestration layer, linking asset prices and valuations with collateral movements, eligibility checks, margin calculations, and settlement instructions.
This collaboration builds on a 2024 pilot program called Smart NAV, where DTCC and Chainlink tested the delivery of mutual fund net asset value data onto blockchains with participants like JPMorgan, Franklin Templeton, and BNY Mellon. The AppChain was initially introduced during DTCC’s Great Collateral Experiment.
Chainlink co-founder Sergey Nazarov noted that the Chainlink Runtime Environment will manage critical outputs in a secure, private, and compliant manner. He described collateral management as the killer application that traditional finance has been anticipating from blockchain technology. Following the announcement, LINK’s value increased by over 20% as investors responded positively to this institutional endorsement.
In addition, DTCC revealed that a separate tokenization service is set to launch in October 2026. Over 50 companies have already joined its tokenized services working group, with a limited live-transaction test scheduled for July. The partnership with Chainlink covers the entire collateral lifecycle, from initial pricing data to final settlement, building on previous institutional collaborations with SWIFT, UBS, and the Bank of England.
This deal represents one of the most significant integrations of Chainlink’s infrastructure with Wall Street’s post-trade clearing system. If the Q4 2026 production launch happens as planned, it would mark the first time a clearinghouse regulated by both the CFTC and SEC operates collateral workflows across multiple blockchains continuously, without traditional market-hour limitations.
