Cayman Islands-based Chainlink wants to stimulate innovation in the Web3 world. The startup, which raised some $32 million in its initial coin offering in 2017, believes the key to this is connecting a complex smart contract to the real world.

A secure and reliable channel to access and verify external events—such as market prices, IoT events, and shipping data—is needed for smart contracts to improve on today's insurance bonds, securities, e-signatures and cross border bank payments. Chainlink is building such a channel by drawing on networks of decentralized, independent oracle providers for ultra-secure and accurate data.

It’s also partnering with everything it can, from major companies, to decentralized startups. Chainlink believes that developing this ecosystem will scale up smart contract development and create conditions similar to what occurred when e-commerce took off on today’s web platforms.

Back in March, Chainlink CEO, Sergey Nazarov told us the project had more than 21 partnerships in the bag.  But we’ve since found out there are at least 30 companies using, testing or proving its oracle service.* Here’s our canonical list:


Accord Project

Accord Project is building smart legal contracts, hence its interest in Chainlink. Project members include many leading lawyers and enterprise blockchain developers, including IBM and HyperLedger, who want to create an open-source source implementation for oracle data.

Announced July 2018


Bodhi is a prediction market which launched on the Qtum mainnet in early 2018. It runs on a Proof of Agreement consensus mechanism, which is currently “purely manual.” In the next stage of its evolution, it plans to integrate Chainlink oracles to improve its efficiency.

Brave New Coin

Brave New Coin (BNC) is a data and research company focused on the blockchain and cryptographic assets industry and founded in 2014. Recently BNC has been developing a marketplace for third-party applications, news-feeds, research and market data products unlocked through the BNC utility token.

The first application on its platform is aimed at crypto investors and traders, and BNC is working with Chainlink as their data provider to create “individual smart contract oracles” to connect to repayment data.

BNC has also teamed up with Nasdaq on the Bitcoin, Ethereum and Ripple Liquid Indexes, which has resulted in speculation that ChainLink will be used to access price data.

Town Crier is described as a “high-trust bridge” between the Ethereum blockchain and online data sources. It’s patent-pending system contains a program that runs inside an isolated piece of hardware called a “secure enclave.” Its function is to protect the program from malicious attacks and keep the computation confidential when it answers data queries from smart contracts; it does this after retrieving answers from external websites.

Announced: November 2018

Around 95 percent of Ethereum smart contracts are built on ZeppelinOS libraries.

Based in Argentina, the startup makes tools for fast, easy and secure smart contract development on the Ethereum blockchain.

It partnered with Chainlink to enable its smart contracts to access data—like the current price of Ether and gas, transaction pool size, and average mining block times on the blockchain. “Outsourcing to a veteran oracle provider means that our team can focus on platform development rather than creating the oracle’s infrastructure,” Zeppelin said in a blog post.


Announced: December 2017

Unconfirmed partnerships

Chainlink’s unconfirmed partnerships are sometimes referred to as “white label,” which means that its services are sometimes unacknowledged, but have been integrated by big, mainstream platforms and built into their protocol stack.

Chainlink’s relationship with banking technology provider SWIFT could fit this category. Chainlink won a Swift awardthe Innotribe Startup Challenge, in 2016—and went on to develop a Proof of Concept, culminating in a presentation at SIBOS, a key financial industry conference.

The proof of concept pulled interest rates from five banks (Barclays, BNP Paribas, Fidelity, Societe Generale and Santander) and fed the data into a smart contract, which was used to make a payment that translated into a SWIFT payment message.

The relationship has remained unacknowledged, though Chainlink has implied that it’s ongoing, and lists SWIFT on its website.

Other possible “white label” partners include Salesforce and Microsoft Azure’s smart contract software developer kit, Cryptlets, which many argue is using Chainlink (one reddit user sets out the argument here.)

Thanks to reddit user, Comfortcooker for this list and to anonymous twitter users @LINKNewsOracle, @CryptoOracle and @finrekt for further resources.

*Some of Chainlink’s partnerships refer to it as “SmartContract,” the company that develops the Chainlink network.
