MetaMask is just an Ethereum Browser and Ether wallet. It interacts with Ethereum Dapps and Smart Contracts without running a full Ethereum node. MetaMask add-on can be installed on Chrome, Firefox, Opera, and the new Brave browser. It also allows you to store ERC20 tokens.
First, let’s setup MetaMask in the Chrome browser. Open up a new Chrome browser window and navigate to https://chrome.google.com/webstore/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn and then click on ‘ADD TO CHROME’ to install MetaMask plugin.
Then enter a password, confirm the password, and then click Create for a new Ethereum account. This account allows to send and receive Ether, ERC20 tokens and also allows you to deploy Smart Contracts.
MetaMask will now show you a 12 word recovery key (Seed) as below.
These 12 words are the only way to restore MetaMask accounts if you forget the password. It should be stored in a safe location, such as in a notebook or USB key kept in a safe. Then click on ‘I’VE COPIED IT SOMEWHERE SAFE’. The main screen of MetaMask will open as below.
That’s it you’ve just created a new Ethereum address using MetaMask! You’re address can be found by clicking on the three little black dots and clicking “Copy Address to clipboard”.
