What is the MetaMask Chrome Extension?

MetaMask is a non-custodial wallet available as a browser extension for Chrome (also for Firefox, Brave, Edge). It injects a secure Web3 provider into websites so dApps can request transactions and interact with your wallet — you always review and approve actions.

Quick Install & Setup (Chrome)

Open the official MetaMask download page: metamask.io/download.
Choose **Chrome** and click the Chrome Web Store link to add the extension.
Click **Add to Chrome** → confirm to install the extension.
Open the MetaMask extension (puzzle icon) and choose **Get Started**.
Create a new wallet or import an existing one using your secret recovery phrase (12 words).
Set a strong password for the extension and securely back up your recovery phrase offline.

Core Features in Chrome

dApp Integration

Connect to DeFi platforms, NFT marketplaces, games, and other Web3 apps with one click.

Token & NFT Management

Store, send, and receive ETH, ERC-20 tokens, and view ERC-721/ERC-1155 NFTs.

Custom Networks

Add networks like Polygon, BSC, Optimism, and other EVM-compatible chains.

Permissions & Privacy

Grant and revoke site permissions; transactions require your explicit approval.

Security tip: Only install MetaMask from the official site or the Chrome Web Store link on metamask.io. Never enter your secret recovery phrase into a website — only use it in the extension when importing.

Common Troubleshooting (Chrome)

Extension not visible: Click the Chrome puzzle icon and pin MetaMask to the toolbar.
Popup blocked: Ensure Chrome allows popups for the site you're using when connecting a dApp.
Network missing: Add custom RPC details under Settings → Networks.
Forgot password: You must restore using your secret recovery phrase after reinstalling the extension.

Best Practices & Safety

Back up your recovery phrase offline (paper or metal) and never share it.
Enable hardware wallet integration (Ledger/Trezor) for highest security when using MetaMask.
Review transaction details in the MetaMask popup before confirming.
Limit site permissions and regularly review connected sites under Settings → Connected sites.
Beware of phishing sites and fake extensions — check the publisher and reviews in the Chrome Web Store.

FAQs

Can I use MetaMask without the extension?: Yes — MetaMask also offers a mobile app. The extension is for desktop browser convenience and dApp integration.
Is MetaMask safe for large holdings?: MetaMask is secure, but for large amounts consider combining it with a hardware wallet (Ledger/Trezor) for on-device signing.
What happens if I lose my recovery phrase?: Without the recovery phrase you cannot restore access. Always store it securely offline.
