MetaMask Wallet Extension® | Secure Ethereum Wallet
The MetaMask Extension is a powerful and widely used browser wallet that allows users to securely manage cryptocurrencies and interact with decentralized applications (dApps) directly from their web browser. Acting as a gateway to Web3, MetaMask makes it easy to explore decentralized finance (DeFi), NFTs, blockchain games, and other Web3 platforms without relying on centralized services.
Available as a browser extension for Chrome, Edge, Firefox, and Brave, MetaMask gives users complete ownership of their digital assets and private keys.
What Is the MetaMask Extension?
MetaMask is a non-custodial crypto wallet extension that enables users to store, send, receive, and swap digital assets on Ethereum and other EVM-compatible blockchains. It also serves as a secure authentication tool for logging into Web3 applications.
Unlike centralized wallets or exchanges, MetaMask does not hold your funds. Instead, your private keys are encrypted and stored locally on your device, giving you full control at all times.
How the MetaMask Extension Works
The MetaMask extension connects your browser to blockchain networks, allowing websites to interact with your wallet only after you approve the request. Every action—such as connecting to a dApp or signing a transaction—requires your manual confirmation.
Basic workflow:
- Install the MetaMask extension
- Create or import a wallet
- Secure your recovery phrase
- Connect to supported blockchain networks
- Approve transactions and dApp connections
This design ensures transparency, security, and user control.
How to Install the MetaMask Extension
- Visit the official MetaMask website
- Choose your browser (Chrome, Edge, Firefox, or Brave)
- Add the extension to your browser
- Create a new wallet or import an existing one
