The Depository Trust & Clearing Corporation, the world’s largest post-trade infrastructure provider, currently custodying $114 trillion in liquid assets, has announced it will integrate Chainlink’s decentralised oracle technology into its Collateral AppChain platform, with a planned launch targeting the fourth quarter of 2026.
The move is one of the most significant institutional endorsements of blockchain infrastructure to date. DTCC’s Collateral AppChain is designed to serve as shared infrastructure for custodians, triparty agents, and collateral managers, automating key processes including margining, collateral optimisation, and settlement. By integrating Chainlink, DTCC aims to connect collateral agreements with real-time pricing, valuation, and asset movement data across multiple markets and blockchains, enabling 24/7 collateral management workflows that are currently constrained by legacy systems and manual processes.
Why this matters: A $114 trillion institution goes on-chain
The scale of DTCC’s involvement is hard to overstate. As the clearinghouse underpinning the vast majority of US securities transactions, DTCC’s adoption of Chainlink’s oracle infrastructure is not a pilot project from a crypto-native company, it is a direct signal from the backbone of traditional finance that tokenised collateral management is being treated as a serious operational priority.
Nasdaq research cited in the announcement underscores the urgency driving that shift: 52% of firms surveyed expect to be managing live tokenised collateral by the end of 2026. Yet, 70% of investment banks, custodians, prime brokers, and asset managers report settlement matching and delivery issues on a daily basis, a figure that reflects how deeply manual and fragmented existing collateral workflows remain. DTCC’s Collateral AppChain, powered by Chainlink, is designed to address precisely that gap by creating a unified, automated layer for collateral operations that can run continuously rather than within the constraints of traditional market hours.
Part of a larger wave across market infrastructure
The DTCC-Chainlink integration is not an isolated development. It is the latest in a series of major moves by the world’s largest exchange and market infrastructure companies to build out tokenised securities and settlement infrastructure.
Earlier this month, DTCC also announced plans to pilot trading of tokenised securities in July, ahead of a targeted October launch involving more than 50 firms across traditional and digital finance, including BlackRock, Circle, Anchorage Digital, and Fireblocks.
In March, Intercontinental Exchange, the parent company of the New York Stock Exchange, signed an agreement with tokenisation platform Securitize to develop blockchain-based trading and on-chain settlement infrastructure, including plans for tokenised shares and exchange-traded funds supporting 24/7 trading. That same month, the US Securities and Exchange Commission approved Nasdaq’s proposal to pilot tokenised stocks and ETFs alongside traditional securities on existing exchange infrastructure, initially covering select Russell 1000 stocks and major index-tracking ETFs. Nasdaq also separately partnered with crypto exchange Kraken and tokenisation firm Backed to develop blockchain-based equities infrastructure.
The cumulative picture is significant. According to RWA.xyz, tokenised stocks have grown from roughly $511 million in on-chain value a year ago to more than $1.4 billion today, an increase of approximately 180% in twelve months. The DTCC-Chainlink announcement suggests the next phase of that growth will be driven not by crypto-native platforms, but by the incumbents of global finance building the infrastructure themselves.
For Chainlink, the integration represents a validation of its oracle network at the highest level of institutional finance, and for the broader tokenisation narrative, DTCC’s commitment to a Q4 2026 go-live puts a firm timeline on what was, until recently, a largely theoretical future.
