Twelve Data Launches Chainlink Node, Bringing Non-U.S. Equities, ETF, and Index Prices to DeFi

Twelve Data is excited to announce that we have launched an official Chainlink node to bring our world class datasets onto leading blockchain networks. Smart contract developers can now call the Twelve Data Chainlink node to access high-quality financial data on-demand for real-time and delayed prices for non-US equities, ETFs, and indexes. This data can be used by smart contract developers to settle on-chain derivatives markets, price synthetic assets, trigger on-chain trading strategies, and support various other DeFi and CeFi related products and markets.

Any developers wanting to consume Twelve Data’s data on-chain within their DeFi application, refer to the following documentation here.

We elected to supply and sell our financial data on-chain using Chainlink because it is the most widely used and time-tested decentralized oracle network in both the blockchain and data provider industry. The Chainlink node enables us to sell our data directly into emerging blockchain-based DeFi markets in a quick and seamless manner. Our Chainlink node is also blockchain-agnostic and cryptographically signs data, giving us a futureproof gateway to any blockchain and a way to prove the integrity of our data to smart contract applications consuming it. For a more detailed explanation of why we selected Chainlink, view our previous announcement.
Workflow of Twelve Data's node
Twelve Data is a leading data aggregation firm that processes a wide range of financial market data across multiple asset classes to provide institutional-grade financial reference data to large trading firms, fintechs, market research firms, and now DeFi applications. Our data has broad market coverage across hundreds of traditional and cryptocurrency exchanges, with over 700M API requests a day spanning more than 80,000 financial assets.

We’re delighted to launch a Chainlink node and enter the DeFi economy gaining traction as an transparent, tamper-proof, permissionless, and globally accessible financial system. We’re confident that our extensive industry experience in managing robust data infrastructure and refining accurate data will provide smart contract developers with the data quality they need to build reliable products across traditional and cryptocurrency asset classes.

“Integrating with Chainlink was a seamless process that quickly introduced our existing API infrastructure to a broad and growing set of new blockchain markets,” stated Yury Sokolov, CEO of Twelve Data. “Not only does our own Chainlink nodes allows us to sell our institutional-grade data directly to smart contracts, but it will cryptographically sign it so users can feel confident in using it on-chain to secure high value contracts knowing it came direct from our APIs.”
