The Depository Trust & Clearing Corporation (DTCC) will use Chainlink infrastructure as its blockchain-based collateral management platform, extending early work between the two companies into one of Wall Street’s core risk management functions.
The company said its collateral application chain will use Chainlink’s runtime environment (CRE) and data standards to support pricing, valuation, margining, collateral optimization and settlement. AppChain is a Besu-based blockchain platform that facilitates asset tokenization and real-time, 24/7 collateral management.
DTCC’s platform is designed to reduce latency and fragmentation in today’s mortgage system, where assets are often trapped across institutions and time zones. By tokenizing collateral and automating workflows through smart contracts, the system is designed to enable near-real-time movement of collateral across traditional financial markets and blockchain networks.
Nadine Chakar, Managing Director and Global Head of Digital Assets at DTCC, said: “By modernizing collateral liquidity using tokenization and distributed ledger technology (DLT), we aim to enable 24/7, near real-time collateral management across global markets and blockchain.”
Chainlink will provide the data and orchestration layer. Its technology will help connect asset prices, valuations and collateral flows while supporting checks on eligibility, margin and settlement instructions. Chainlink is a decentralized oracle network that provides real-world data such as prices, weather, and APIs to the blockchain, since the blockchain itself cannot access external information on its own.
The platform operates within DTCC’s AppChain setup. DTCC, which launched a tokenized collateral platform last year, said collateral liquidity could become a key institutional use case for blockchain technology.
The Chainlink collaboration builds on Smart NAV, a 2024 pilot in which DTCC and Chainlink tested bringing mutual fund net asset value data to the blockchain.
JPMorgan Chase, Franklin Templeton, and BNY Mellon participated in the pilot project, which focuses on tokenizing funds across multiple chains.
DTCC has also been expanding tokenization efforts beyond collateral. The company said earlier this month that more than 50 companies have joined the working group for The Depository Trust Company’s tokenization service, with limited production transactions scheduled for July and a planned launch in October.
DTCC’s subsidiaries processed $4.7 trillion in securities transactions in 2025. Its custody subsidiary provides custody and asset services for $114 trillion worth of securities issuances.
