MetaMask for Browser


A Simple Way to Use Crypto Online

The MetaMask extension is a secure, browser-based wallet for Ethereum and other compatible blockchains. It lets users manage tokens, interact with decentralized apps (DApps), and store digital assets directly from browsers like Chrome, Firefox, Edge, or Brave.

With MetaMask, you hold your own keys and keep control of your crypto—no centralized account needed.

What Is MetaMask?

MetaMask is a non-custodial crypto wallet that works as a browser extension. It stores Ethereum, ERC-20 tokens, NFTs, and more. It’s used to connect to Web3 platforms, including decentralized exchanges, NFT markets, and blockchain-based games.

The wallet encrypts your keys locally, so only you can access your funds. It's widely used by beginners and developers alike for secure access to blockchain apps.

What MetaMask Can Do

Store and Send Tokens

You can store ETH, ERC-20, and other tokens. You can send and receive funds directly from the extension interface.

Connect to Web3

MetaMask links to decentralized apps automatically. You just click “Connect” when a site asks. This lets you trade tokens, stake crypto, or use DeFi services with ease.

Swap Assets

The built-in swap feature lets you trade tokens within the extension. MetaMask compares prices across platforms to give you the best rate.

Add Custom Networks

Besides Ethereum, MetaMask supports other networks like Polygon, BNB Chain, and Arbitrum. You can add them manually with RPC settings.

Supported Browsers

MetaMask works with:

  • Google Chrome
  • Mozilla Firefox
  • Microsoft Edge
  • Brave

After installing, the MetaMask icon appears in your browser. Clicking it opens your wallet.

How to Install MetaMask

Step 1: Download

Visit and click “Download.” Choose your browser to install the extension.

Step 2: Set Up Wallet

After installation, open MetaMask. Choose to either create a new wallet or import an existing one using your 12-word phrase.

Step 3: Secure It

Create a strong password. Save your recovery phrase somewhere safe. This is the only way to restore your wallet if needed.

Logging In

Open MetaMask from the browser toolbar and enter your password to access the wallet. After periods of inactivity, MetaMask locks your session. To unlock it, simply re-enter the password.

To log out manually, click your account icon and choose "Lock."

Wallet Recovery

Forgot Your Password?

MetaMask doesn’t support password resets. You must reinstall and recover your wallet with the recovery phrase.

Lost Access?

Without your recovery phrase, there’s no way to restore your wallet. Always back it up offline and store it safely.

Using MetaMask on Multiple Devices

Want to access MetaMask from another browser or device? Follow these steps:

  1. Install MetaMask on the new browser
  2. Select “Import Wallet”
  3. Enter your 12-word recovery phrase
  4. Set a new password

Now you can access your wallet from multiple locations, though each must be set up manually.
