Example Walkthrough


This section is designed to support your next steps in launching a successful Chainlinked project by providing a complete example of executing a Chainlink project from start to finish.

After following this step-by-step guide for deploying a Chainlinked contract, you will:

  • Deploy a testnet contract on Kovan
  • Fund your contract with testnet LINK
  • Request and receive data (ETH/USD price)
  • View the data from your contract

There are no setup steps or prerequisites. This guide will walk you through every step with images. The examples in this guide use Remix so you don't need to setup a development environment. You do not need to run a Chainlink or Ethereum node to complete this guide.
