Getting Started With MetaMask (Part 1)

Ready to Fox-trot?

What is MetaMask?

MetaMask is a web extension, which allows you to manage your Ethereum private keys via your web browser. By doing so, it serves as a wallet for Ether and ERC20 tokens, and allows you to visit the distributed web of tomorrow in your browser today. To be more specific, it allows you to run Ethereum dApps (Decentralized Apps) right in your browser without running a full Ethereum node. ( It means you don’t have to download and sync the full blockchain on your device/computer). Our mission is to make Ethereum as easy to use for as many people as possible.

Note:

When adding MetaMask to your browser, you may ask why you’d have to approve an extension to “read and change all your data on the websites your visit”.

In order to enable dApps (Distributed Apps) to access the blockchain, MetaMask needs to inject a web3 Javascript object into each page. By doing so, it will not change the website, but merely allows it to access the network.

If you are still not convinced, a good way to experiment and manage your browser is to sandbox your MetaMask, i.e. creating, say, a Chrome profile where MetaMask is only installed in browser with that profile. This way,  you could browse with or without MetaMask at will.

That said, MetaMask is safe for browsing. Welcome to join over a million MetaMask users in the world!
