We’re excited to introduce DataLink—the institutional-grade data publishing service powered by Chainlink. DataLink is a turnkey service that enables institutions to seamlessly publish data to blockchains and unlock the benefits of the onchain economy without the cost or complexity of building new infrastructure. By leveraging the Chainlink data standard to provide secure access to the same high-quality data institutions already rely on, DataLink accelerates institutional adoption of digital assets and enables organizations to rapidly scale onchain.

Deutsche Börse Market Data + Services has formed a strategic partnership with Chainlink to bring its multi-asset class market data to blockchains. For the first time, real-time data from the largest derivatives exchange in Europe, Deutsche Börse Group’s Eurex, along with Xetra, 360T, and Tradegate trading venues—spanning equities, derivatives, forex instruments, and more—is being made available onchain. This milestone sets a new standard for how institutional-grade market data is accessed and used in the digital asset economy.

DataLink is launching on 40+ blockchain mainnets, with many more to come.

With demand for tokenized real-world assets expected to reach $30.1 trillion, DataLink empowers banking and capital markets institutions to establish leadership in the onchain economy and unlock new revenue streams. At the same time, developers building with DataLink gain faster access to institutional-grade data, enabling them to build new products more rapidly, launch assets, and support robust markets underpinned by high-quality data.

Deutsche Börse Market Data + Services Partners With Chainlink To Publish Market Data Onchain Via DataLink

Deutsche Börse Market Data + Services is bringing its multi-asset class market data to blockchains for the first time.
