First EU-Regulated Onchain Exchange 21X Adopts Chainlink Live in Production

FRANKFURT, Germany, Sept. 15, 2025 /PRNewswire/ -- Chainlink, the industry-standard oracle platform, and 21X, the first blockchain-based exchange for tokenized securities licensed under the EU's DLT Regime, today announced that 21X has adopted Chainlink to deliver market data onchain for its tokenized securities.

Live-in-production and powered by the Chainlink Runtime Environment (CRE), Chainlink enables verifiable market data, including the best bid and ask prices with corresponding quantities, as well as the last traded prices for securities listed on the 21X platform. This data can be accessed directly on the public Polygon blockchain in real-time. This enables an array of new use cases for EU-regulated tokenized equities, debt securities, and funds, from collateral in lending protocols to automated portfolio rebalancing.

"The Chainlink standard enables 21X to securely and reliably bring real-time, verifiable market data for tokenized securities onchain," said Max Heinzle, CEO of 21X. "By integrating Chainlink into our regulated DLT trading venue, we're delivering the transparency, auditability, and collateral utility that institutions require to move onchain. Adopting Chainlink is a foundational step in bridging traditional capital markets with the blockchain economy."

Unlocking Unparalleled Utility in Regulated Onchain Markets
Now, with Chainlink's infrastructure in place, which secures the majority of DeFi and has enabled tens of trillions in transaction value, 21X's market data is automatically retrieved from onchain contracts, aggregated, and published in a standardized, machine-readable format on the Polygon network.

This CRE-powered workflow provides a verifiable source of truth for market participants, streamlining integration for developers. As a result, data from the 21X platform is seamlessly accessible by market participants as well as custody providers, DeFi protocols, and risk management systems thereby unlocking real-time valuations for tokenized securities.

"We're excited that 21X, the first fully regulated onchain market for trading and settlement, has adopted the Chainlink data standard," said Fernando Vazquez, President of Banking & Capital Markets at Chainlink Labs. "With Chainlink making 21X's EU-regulated tokenized securities more usable across the onchain economy and helping bring institutional-grade assets to DeFi protocols across the globe, this is a pivotal moment for the blockchain economy as it opens the floodgates of institutional capital to flow onchain."

Laying the Foundation for Scalable, Composable Capital Markets
Looking ahead, 21X plans to expand the integration with Chainlink to include pre-trade data, deeper analytics, and additional asset classes, continuing to enhance the utility of onchain markets. All data will remain accessible via the 21X platform interface and onchain endpoints—empowering financial institutions, developers, and regulators alike to interact with live, high-integrity market data at the core of an evolving digital asset ecosystem. This integration is a major step toward building a more transparent, composable, and efficient financial system, which opens the floodgates for institutional capital to move onchain.
