The Depository Trust & Clearing Corporation (DTCC), which underpins the U.S. securities market, announced it will integrate Chainlink's infrastructure to build its Collateral AppChain, a platform designed to bring 24/7 efficiency to collateral management.
"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," Nadine Chakar, DTCC’s managing director and global head of digital assets, said in a statement.
The new platform, slated to go live in the fourth quarter of 2026, will run on a Hyperledger Besu blockchain. It will utilize Chainlink's Runtime Environment (CRE) to handle data and automation for asset pricing, valuation, margining, and settlement. This replaces one-off data integrations with a reusable framework, aiming to reduce delays in a system where assets are often siloed across different institutions and time zones.
The move represents one of the most significant adoptions of blockchain by traditional finance, given DTCC's scale. The firm processed $4.7 quadrillion in securities transactions in 2025 and held $114 trillion in assets in custody. The partnership builds on a 2024 pilot, Smart NAV, which involved JPMorgan, BNY Mellon, and Franklin Templeton testing the use of Chainlink to bring mutual fund data on-chain.
Bridging TradFi and On-Chain Finance
The core problem the Collateral AppChain aims to solve is the fragmentation and inefficiency of the current collateral system. By tokenizing collateral and using smart contracts for automation, the platform is designed to free up capital and reduce reconciliation errors.
Chainlink's CRE will serve as the orchestration layer, coordinating workflows for eligibility checks, collateral optimization, and settlement instructions across both blockchain and legacy systems. "Collateral management is the killer application that institutional finance has been waiting for from the blockchain sector," said Chainlink Co-Founder Sergey Nazarov, adding that the CRE can "pull together and orchestrate many critical outputs in a secure, private and compliant manner."
DTCC's blockchain ambitions extend beyond this single project. The organization recently announced that over 50 firms have joined a working group for a separate tokenized services platform, with a limited live-transaction test planned for July and a full launch scheduled for October. This indicates a broad strategic push towards leveraging distributed ledger technology across its operations.
