MetaMask has emerged as one of the most popular and user-friendly cryptocurrency wallets and gateway to decentralized applications (DApps) on the Ethereum blockchain. If you're new to the world of cryptocurrencies or decentralized finance (DeFi), getting started with MetaMask is a crucial first step. In this guide, we'll walk you through the process of installing MetaMask, creating your wallet, and navigating its key features.
What is MetaMask?
MetaMask is a browser extension that enables users to interact with the Ethereum blockchain seamlessly. It serves as a digital wallet, allowing users to store, manage, and transfer Ethereum and ERC-20 tokens, as well as access decentralized applications.
The extension injects the Ethereum web3 API into every website's javascript context, so that dapps can read from the blockchain.
MetaMask also lets the user create and manage their own identities (via private keys, local client wallet and hardware wallets like Trezor™), so when a Dapp wants to perform a transaction and write to the blockchain, the user gets a secure interface to review the transaction, before approving or rejecting it.
Because it adds functionality to the normal browser context, MetaMask requires the permission to read and write to any webpage. You can always "view the source" of MetaMask the way you do any Chrome extension, or view the source code on Github:
