Metamask® Extension® - Gitbook

Available as a browser extension and as a mobile app, MetaMask equips you with a key vault, secure login, token wallet, and token exchange—everything you need to manage …

MetaMask’s extension opens up access between your web browser and decentralized applications (dApps) built on Ethereum or Ethereum Virtual Machine (EVM) compatible networks. You can think of it like this:

Imagine if you were in one country (like the internet) and wanted to visit another country (like the Ethereum blockchain) that speaks a completely different language and has different customs. It might be hard to communicate or get around, right?

MetaMask is like a friendly translator and guide who helps you navigate this new country. It understands the language and customs of both countries and helps them interact with each other.

When you install MetaMask, it converts your web browser's language into Ethereum's, letting you do things like interact with dApps, sign transactions, and create or manage your Ethereum identity.
