Install Configure & Fund MetaMask

Introduction to MetaMask

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 & Ropsten blockchains very easy and provides you with wallet addresses.

Install & Configure

Go to: 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 Ropsten Test Network.

Fund your address with Ether

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

  • Go to the Ropsten Ether Faucet
  • Paste your address into the text field
  • Click the “Send me test Ether” button
  • Go back to the MetaMask extension to validate the balance. Now you have ETH to play with!
