Key Takeaways:
DTCC will integrate Chainlink’s Runtime Environment into its Collateral Appchain, targeting a Q4 2026 production launch.The platform automates collateral workflows for a firm that processed $4.7 quadrillion in securities transactions in 2025.Chainlink Co-Founder Sergey Nazarov says collateral management is the blockchain sector’s key application for traditional finance (TradFi).Rather than building one-off integrations for each new data type or asset class, DTCC chose CRE for its reusable framework. That design allows the Collateral Appchain to expand across new collateral use cases without rebuilding its data pipeline each time.
DTCC processed securities transactions valued at $4.7 quadrillion in 2025 and held custody of securities from more than 150 countries valued at $114 trillion. Bringing that scale into near-real-time collateral operations represents a significant shift in post-trade infrastructure.
DTCC first unveiled the Collateral Appchain publicly during its Great Collateral Experiment initiative. The platform is now progressing toward a production launch scheduled for the fourth quarter of this year.
CRE is built to operate at institutional scale, a requirement for any infrastructure touching DTCC’s clearing and settlement operations. Its secure, private, and compliant architecture is designed to meet the standards of regulated financial markets.
DTCC operates from 20 locations worldwide and processes more than 25 billion trade messages annually through its Global Trade Repository service. Its Collateral Appchain project places distributed ledger technology (DLT) at the center of that post-trade workflow for the first time.
