Suggest Edits

This page will show you how to configure the MetaMask browser extension. If you already have MetaMask configured, skip to Acquire testnet LINK.

What is MetaMask?

MetaMask is a wallet that runs as a self-contained application inside your browser as an extension. It allows you to interact with Decentralized Applications or "dApps". MetaMask makes accessing the Ethereum & Testnet blockchains (Like Kovan) very easy and provides you with wallet addresses.

Metamask Welcome Screen

Install & Configure

Go to: metamask.io and install the browser extension in Chrome or Firefox.

  • After installing the MetaMask extension, open the extension by clicking on the MetaMask Fox icon. If prompted to use the New Look, do so.
  • Create a new vault.
  • You will be presented with a 12-word mnemonic phrase; copy that phrase down in a very secure location that only you can access.
  • Change the network selection from Main Ethereum Network to the Kovan Test Network.

Fund your address with Ether

In order to obtain Kovan ETH, follow the steps below:

  • Go to the Kovan Ether Faucet.
  • Enter your wallet address into the text box.
  • Hit the button to get "Test ETH", wait a minute, and you'll see it in your wallet!
