DTCC's Great Collateral Experiment achieved near-instant repo settlement on blockchain rails, with The Graph's subgraphs powering the critical data layer.

DTCC Pilots T+5 Second Settlement Using The Graph GRT for Data Infrastructure

The Depository Trust & Clearing Corporation, which settles trillions in annual trade volume, has completed a pilot that slashed traditional settlement times from days to roughly five seconds—with The Graph's indexing protocol serving as the backbone for real-time data queries.

GRT traded at $666.82 as of March 12, down 1.12% over 24 hours, though the token showed no immediate reaction to the blog post detailing the experiment's results.

What DTCC Actually Built

The pilot, internally dubbed the "Great Collateral Experiment," tackled repo agreements—the instruments banks use to manage daily liquidity. Moving collateral for these agreements traditionally involves manual processes constrained by market hours. DTCC's experimental "AppChain" allowed assets to move continuously with near-instant finality.

Here's where it gets interesting for data infrastructure: The Graph's subgraphs handled the query layer, tracking digital assets as they moved through the system. Original assets (BTC or real-world assets) were locked in control accounts while wrapped tokens circulated on the AppChain. Smart contracts automated margin calls and net position calculations that previously required time-consuming manual negotiations.

"For all value to settle, there must be agreement across all chains about the ownership structure," G. Daniel Doney, DTCC's representative, explained during a November 2025 SmartCon discussion. "That requires you to be able to extract the data from the chains and then establish the ownership record for those assets."

The Hidden Cost Problem

Current U.S. markets operate on T+1 settlement—all parties agree within one business day. Most global markets still run T+2. That delay carries costs buried in transaction fees that investors rarely see itemized.

Doney pointed to corporate actions as a pain point: dividend payments flowing through issuers, transfer agents, banks, and brokerages create "multiple interactions between these channels" with "costs in the order of billions of dollars per year, and frequent mistakes due to the complexities of the system."

The pilot demonstrated that when all parties share synchronized state at finality, precautionary over-collateralization drops significantly. Capital that would otherwise sit idle as a buffer can be deployed elsewhere.

Why This Matters Beyond DTCC

This experiment lands amid broader infrastructure transformation in global finance. Data centers captured over one-fifth of global greenfield investment in 2025, driven largely by demand for AI and digital networks. The Financial Data and Markets Infrastructure industry has become one of the fastest-growing segments in financial services.

Andrew Clews, Enterprise Strategy & Governance Lead at The Graph Foundation, framed the stakes personally: "When settlement becomes real-time, transparent, and verifiable, risk stops being quietly passed downstream to the people least equipped to bear it."

The pilot validated a specific architecture but left questions unanswered about production timelines, regulatory approval, and how existing market participants would transition. DTCC hasn't announced when—or if—this moves beyond experimentation.

For GRT holders, the institutional validation matters more than immediate price action. If blockchain settlement becomes standard for repo markets, the data layer becomes critical infrastructure rather than optional tooling. That's a fundamentally different value proposition than powering DeFi dashboards.
