Chainlink Partners with DTCC for 24/7 Collateral Management via New AppChain

The Depository Trust & Clearing Corporation (DTCC) has announced a collaboration with Chainlink to integrate its Runtime Environment into a new platform called the Collateral AppChain. This initiative aims to provide round-the-clock, near real-time collateral management for financial markets that currently rely on outdated systems.

DTCC, which processed a staggering $4.7 quadrillion in securities transactions in 2025 and manages $114 trillion in assets from investors across over 150 countries, is looking to modernize its operations. The Collateral AppChain will be built on Hyperledger Besu, a permissioned blockchain, and will utilize Chainlink’s infrastructure to facilitate the flow of information between various blockchains and financial systems.

This integration will automate workflows covering the entire collateral lifecycle, including eligibility checking, asset valuation, margin calculation, and final settlement. The goal is to significantly reduce the time currently taken for these processes, compressing what can take hours or even days into a continuous operation.

DTCC plans to launch the Collateral AppChain in the fourth quarter of 2026. This partnership follows Chainlink’s previous involvement in a pilot program with major financial institutions like JPMorgan and BNY Mellon, which explored the delivery of mutual fund net asset value data onto blockchain networks.

By choosing to build on a permissioned blockchain rather than a public one, DTCC reflects the cautious approach of regulated financial entities. However, the integration with Chainlink is designed to connect this permissioned environment with the broader blockchain ecosystem, ensuring that the AppChain does not operate in isolation.
