DTCC builds out blockchain-based collateral system with Chainlink integration

The platform tokenizes collateral on blockchain rails and uses smart contracts to enable 24/7 automated collateral management across financial markets.

What to know:

• DTCC will use Chainlink for its blockchain-based Collateral AppChain to automate risk-management functions like pricing, valuation, and settlement.
• The platform tokenizes collateral on blockchain rails and uses smart contracts to enable 24/7 automated collateral management across financial markets.
• This collaboration follows the Smart NAV pilot with JPMorgan and BNY Mellon. DTCC plans a separate new tokenization service launch in October.

The Depository Trust & Clearing Corporation (DTCC) will use Chainlink infrastructure for its blockchain-based collateral management platform, extending earlier work between the firms into one of Wall Street’s core risk-management functions.

The firm said its Collateral AppChain will use Chainlink’s Runtime Environment (CRE) and data standard to support pricing, valuation, margining, collateral optimization and settlement. The AppChain is a Besu-based blockchain platform facilitating tokenization of assets and real-time, 24/7 collateral management.

DTCC’s platform is aimed at reducing the delays and fragmentation in today’s collateral systems, 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 collateral movement across both traditional financial markets and blockchain networks.

“By leveraging tokenization and distributed ledger technology (DLT) 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.

Chainlink will provide the data and orchestration layer. Its technology will help connect asset prices, valuations and collateral movement, while supporting checks on eligibility, margining and settlement instructions. Chainlink is a decentralized oracle network that feeds blockchains with real-world data such as prices, weather, and APIs since blockchains cannot natively access external information on their own.

The platform runs within DTCC’s AppChain setup. DTCC unveiled the tokenized collateral platform last year, saying collateral mobility could become a key institutional use case for blockchain technology.

The Chainlink tie-up builds on Smart NAV, a 2024 pilot in which DTCC and Chainlink tested bringing mutual fund net asset value data onto blockchains.

JPMorgan, Franklin Templeton and BNY Mellon participated in the pilot, which focused on fund tokenization across multiple chains.

DTCC has also been expanding tokenization work beyond collateral. The company said earlier this month that more than 50 firms had joined a working group for The Depository Trust Company’s tokenization service, with limited production trades planned for July and a launch planned for October.

DTCC’s subsidiaries processed $4.7 quadrillion in securities transactions in 2025. Its depository subsidiary provided custody and asset servicing for securities issues valued at $114 trillion.
