MetaMask

MetaMask is a lightweight Chrome browser-based extension that helps in interacting with Ethereum networks. It is also a wallet that helps in sending and receiving Ether. MetaMask can be downloaded from https://metamask.io/. Since MetaMask runs in a browser, it does not download the entire chaindata locally; instead, it stores it centrally and helps users connect to their store using the browser. Let's take a look at the following steps:

MetaMask should be added as an extension as shown in the following screenshot:
