21X Integrates Chainlink to Enhance Tokenised Securities Trading

On September 15, 2025, in Germany, 21X announced its integration of Chainlink, an established oracle platform, to enhance the delivery of market data for its tokenised securities. This partnership allows 21X to provide verifiable market data directly on-chain, facilitating a more transparent trading environment for its users.

The integration is live and operational, utilizing the Chainlink Runtime Environment (CRE). With this technology, 21X can offer real-time access to key market metrics such as the best bid and ask prices, corresponding quantities, and last traded prices for the securities listed on its platform. This data is available on the public Polygon blockchain, ensuring that users receive timely and accurate information.

Max Heinzle, CEO of 21X, commented on the significance of this development. He stated, “The Chainlink standard enables 21X to securely and reliably bring real-time, verifiable, market data for tokenised securities on-chain. By integrating Chainlink into our regulated DLT trading venue, we’re delivering the transparency, auditability, and collateral utility that institutions require to move on-chain.” He emphasized that adopting Chainlink represents a critical step in connecting traditional capital markets with the blockchain economy.

With Chainlink’s infrastructure already securing a significant portion of decentralised finance (DeFi), which has facilitated transactions worth tens of trillions, 21X can now automatically retrieve market data from on-chain contracts. This data is aggregated and published in a standardised, machine-readable format on the Polygon network. Such a workflow, powered by the CRE, offers a verifiable source of truth for market participants and simplifies integration for developers.

Fernando Vazquez, president of banking and capital markets at Chainlink Labs, expressed enthusiasm about the collaboration. He stated, “We’re excited that 21X, the first fully regulated on-chain market for trading and settlement, has adopted the Chainlink data standard. With Chainlink making 21X’s EU-regulated tokenised securities more usable across the on-chain 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 on-chain.”

The integration of Chainlink marks a significant advancement in the trading of tokenised securities, highlighting the growing intersection of traditional finance and blockchain technology. As more institutions seek to leverage the benefits of decentralisation, partnerships like that of 21X and Chainlink are poised to play a crucial role in shaping the future of finance.
