The MetaMask mobile app consists of two main parts: a wallet and a web browser. The wallet supports any token compatible with Ethereum, and the web browser is preconfigured for interacting with dapps and smart-contracts.
MetaMask was first released in 2016, as a browser-extension, by ConsenSys - the first company focused on building decentralized tools and infrastructure. Both MetaMask and ConsenSys have played monumental roles in bringing Ethereum to the mainstream.
It is hard to overstate the effect MetaMask has had on the Ethereum ecosystem. By making dapps and smart-contracts simple and intuitive to use, activity on the Ethereum blockchain has enjoyed consistent growth.
Metamask is an open-source wallet, active development happens on github. The wallet has tons of features, and is constantly being updated and improved.
MetaMask is available as a browser-extension for Chrome, Firefox, Brave, and Edge. In September of 2020, MetaMask released a mobile app for iOS and Android.
In order to set up a new wallet, here are some easy steps that you are required to follow after you are done installing the MetaMask extension or the Android or iOS application:
Click on the "MetaMask icon" from the list of available extensions
Then, select the "Get Started" button to proceed to the next step
On the right side, click the "Create a wallet" button
Go through the detailed information on the next page and select the "I Agree" or "No Thanks" option
It's time to set up your MetaMask sign in password and enter it two times
And tap "Create" to reveal your wallet's secret recovery phrase which needs to be noted down
After following some more steps, your wallet would be created
Now, you are all set to sign in and use your wallet to access the Ethereum-based dapps or to start making transactions through it. However, if you do not know the procedure to sign in to your MetaMask account, then you can follow the steps given in the section below.
