21X Integrates Chainlink to Enhance On-Chain Market Data

On September 15, 2025, 21X, a blockchain-based exchange for tokenised securities, announced its adoption of Chainlink, an oracle platform, to provide on-chain market data for its offerings. This integration aims to enhance the transparency and reliability of market information, which is crucial for institutional investors operating in the blockchain economy.

Transforming Market Data Accessibility

By utilizing the Chainlink Runtime Environment (CRE), 21X will deliver real-time and verifiable market data directly on the public Polygon blockchain. The data includes vital indicators such as best bid and ask prices along with corresponding quantities, as well as the last traded prices for securities listed on the 21X platform.

Max Heinzle, CEO of 21X, emphasized the significance of this integration, stating, “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.”

Heinzle further noted that adopting Chainlink represents a foundational step in connecting traditional capital markets with the blockchain economy.

Enhancing Institutional Access to Blockchain

The infrastructure provided by Chainlink secures a significant portion of decentralised finance (DeFi) and has facilitated transactions amounting to tens of trillions of dollars. With this system in place, market data for 21X will be automatically retrieved from on-chain contracts, aggregated, and published in a machine-readable format on the Polygon network. This process aims to streamline integration for developers while providing a verifiable source of truth for market participants.

Fernando Vazquez, President of Banking and Capital Markets at Chainlink Labs, expressed enthusiasm about the partnership, stating, “We’re excited that 21X, the first fully regulated on-chain market for trading and settlement, has adopted the Chainlink data standard. This integration makes 21X’s EU-regulated tokenised securities more usable across the on-chain economy and aids in bringing institutional-grade assets to DeFi protocols worldwide.”

Vazquez described this as a pivotal moment for the blockchain economy, opening the floodgates for institutional capital to flow on-chain.

The collaboration between 21X and Chainlink marks a significant advancement in the use of blockchain technology for regulated financial markets, potentially reshaping how securities are traded and settled in the future.
