Chainlink Using Activ Financial to Bring Traditional Market Data to DeFi

We are excited to announce that Chainlink is collaborating with Activ Financial to make premium traditional market data feeds available to developers across leading blockchain networks. Chainlink is the industry-leading decentralized oracle network, enabling blockchain-based applications built using smart contracts to access data and services from external APIs. In the case of Activ Financial, Chainlink is using a decentralized network of nodes to fetch price data from the Activ Financial API, aggregate it with other sources, and deliver it on-chain as a single trusted data point for use by smart contract applications.


Activ Financial is a global provider of real-time, multi-asset financial market data and solutions that encompass global content management and data delivery for enterprises and soon blockchain markets via Chainlink. With coverage spanning more than 150 equity and derivatives exchanges around the world, Activ is an end-to-end, independent market data provider.


Chainlink will leverage Activ Financial’s data within decentralized Price Feeds that supply real-time level-1 equities data into emerging blockchain markets, specifically decentralized finance (DeFi)—a parallel financial ecosystem consisting of open-source, permissionally accessible, tamper-proof financial products built and run on top of blockchains. Once on-chain, Chainlink Price Feeds can be used within DeFi applications to enable these applications to better perform various on-chain actions like settling futures and options contracts, executing on-chain trading strategies, and more.


We are excited to collaborate with Chainlink because it has the largest and fastest growing ecosystem of data providers and smart contract developers using its oracles to buy and sell data between one another. In addition to being widely adopted, Chainlink has several technical advantages that make ideal for data providers, including:


  • High-Quality Data - Chainlink oracle nodes can manage API keys and account logins, allowing our data to be purchased and utilized through the same API subscription model we already employ today.

  • Blockchain Agnostic - Chainlink is blockchain agnostic, serving as a future-proof oracle solution where we can sell our data to any current and future blockchain

  • Time-Tested Infrastructure - Chainlink is thoroughly audited open-source software that helps collectively secure tens of billions of dollars in value for live DeFi applications, proving its ability to help secure high value contracts.

  • Industry Standard - Chainlink is the most widely used oracle solution in DeFi, offering a large and growing market of new data consumers for our APIs.


We’re excited to integrate our market data within Chainlink Price Feeds deployed across numerous top blockchains, ultimately helping Activ Financial enter the high-growth DeFi markets in a simple, secure, and accelerated manner.
