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 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: 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 award—the 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.
