MetaMask Chrome Extension Guide
The MetaMask Chrome Extension is a browser-based cryptocurrency wallet that allows users to securely manage Ethereum and other EVM-compatible assets directly from Chrome. It also acts as a gateway to decentralized applications (dApps) without exposing private keys online.
What is MetaMask?
MetaMask is a non-custodial wallet, meaning you control your private keys and funds. The Chrome extension allows seamless access to Ethereum, Binance Smart Chain, Polygon, and other blockchain networks. You can send, receive, and store tokens, interact with dApps, and sign blockchain transactions directly from your browser.
Installing MetaMask Chrome Extension
To install safely, follow these steps:
- Open the official Chrome Web Store page: MetaMask on Chrome Web Store
- Click "Add to Chrome" and confirm the installation.
- Once installed, a MetaMask icon will appear in your Chrome toolbar.
- Click the icon to launch the extension and begin setup.
Creating a New Wallet
If you are new to MetaMask:
- Click "Get Started".
- Choose "Create a Wallet".
- Create a strong password to unlock the extension on your browser.
- MetaMask will generate a 12-word recovery phrase (seed phrase). Write it down and store it securely offline.
Never share your recovery phrase with anyone. Anyone with this phrase can access your funds.
Importing an Existing Wallet
If you already have a MetaMask or other compatible wallet:
- Click "Import Wallet" instead of creating a new one.
- Enter your 12-word or 24-word recovery phrase.
- Create a password for browser access.
Connecting to dApps
MetaMask allows you to interact with decentralized applications safely:
- Visit a supported dApp website (e.g., OpenSea, Uniswap, Aave).
- Click "Connect Wallet" on the dApp.
- Select MetaMask in the popup and confirm connection.
- All transactions must be verified on your MetaMask extension before execution.
Sending and Receiving Tokens
- To send tokens, click "Send", enter the recipient address, select the token, and confirm the transaction.
- To receive tokens, click "Account" and copy your public address. Share this address for deposits only.
- All transactions require verification through your MetaMask extension.
Security Best Practices
- Install MetaMask only from the official Chrome Web Store link.
- Never share your recovery phrase or password.
- Enable hardware wallet integration (Ledger, Trezor) for extra security.
- Always verify URLs of dApps and contracts before interacting.
- Keep MetaMask extension updated to the latest version.
