What Is MetaMask?

MetaMask is a browser-based crypto wallet that allows easy interaction with the Ethereum blockchain and its various decentralized applications (dApps). At its core, MetaMask manages your Ethereum account keys and allows you to:

  • Securely store, send, and receive ETH and ERC-20 tokens
  • Access and interact with dApps and DeFi protocols
  • Connect to Web3 sites and applications
  • View Ethereum (for example on Etherscan) wallet activity and balances

Beyond just a wallet, MetaMask acts as a gateway to the growing Web3 ecosystem. With so many dApps and services requiring MetaMask, it has become the de facto Ethereum wallet for crypto users.

Setting Up MetaMask

Getting started with MetaMask takes just a few minutes:

  3. Fund your MetaMask wallet by buying ETH directly or transferring from another wallet or exchange.
  4. Connect MetaMask to Web3 sites and dApps by clicking “Connect” and selecting MetaMask.

With MetaMask now set up and funded, you have full access to the world of Ethereum and dApps!
