Select the browser extension option.
Choose Chrome.
Follow the link to the official Chrome Web Store listing.
Select Add to Chrome.
Confirm the extension installation.
Open MetaMask after installation.

MetaMask provides tools for managing supported accounts, viewing balances, and reviewing wallet activity.
Compatible dApps can request permission to connect to MetaMask. Review the website and connection request before approving it.
When a dApp requests a transaction or signature, MetaMask displays the request for review. Carefully check what you are authorizing before signing.
MetaMask supports interaction with multiple blockchain networks and related Web3 applications. Available assets and features can vary depending on the network and account configuration.
Because MetaMask is a self-custody wallet, protecting your wallet credentials is essential.
Follow these practices:
Install MetaMask only through official MetaMask resources.
Keep Chrome and MetaMask updated.
Use a strong, unique password.
Secure your Secret Recovery Phrase offline.
Never share your Secret Recovery Phrase or private keys.
Verify dApp websites before connecting.
Review transaction and signature requests carefully.
Avoid unfamiliar browser extensions.
Be cautious of unsolicited support messages.
MetaMask specifically recommends using its official download page or the official browser extension store.
Your Secret Recovery Phrase (SRP) is highly sensitive. Whoever has access to an SRP can generally access the wallet accounts associated with it. MetaMask states that it cannot recover an SRP for you.
Never enter your Secret Recovery Phrase on a website.
Do not provide it through:
Login pages
Emails
Chat messages
Social media
Support forms
Remote-support sessions
Unofficial wallet applications
Fake extensions and phishing websites can imitate MetaMask and attempt to steal wallet credentials.
MetaMask recommends installing the extension through its official download page or the official browser extension store.
Be especially cautious if a website or application asks you to:
Verify your wallet
Upgrade your account
Synchronize your wallet
Unlock your funds
Submit your Secret Recovery Phrase
Provide private keys
MetaMask states that legitimate websites should not ask you for your Secret Recovery Phrase.
When a dApp asks to connect to MetaMask:
Check the website's domain carefully.
Confirm that you recognize the application.
Review the requested account connection.
Examine permissions carefully.
Approve the connection only when you understand it.
A wallet connection does not automatically mean you should approve a transaction. Review every subsequent transaction or signature request independently.
If MetaMask displays a “Deceptive site ahead” warning, MetaMask recommends not connecting your wallet to that site.
If MetaMask does not appear in Chrome:
Open Chrome's Extensions menu.
Check whether MetaMask is installed.
Open the extension-management page.
Confirm that MetaMask is enabled.
Pin the extension to the toolbar if needed.
Restart Chrome if necessary.
Use MetaMask's official support resources for further troubleshooting.
Avoid downloading unofficial versions or manually installing files from unknown sources.
