The MetaMask Extension is a browser-based cryptocurrency wallet that allows users to manage supported digital assets and connect with decentralized applications (dApps). It brings wallet functionality directly into a compatible web browser, making it easier to interact with Web3 services.
MetaMask is a self-custodial wallet, meaning users maintain control of their wallet credentials and are responsible for protecting their recovery information.
The browser extension can be used to:
View supported cryptocurrency balances
Send and receive digital assets
Connect to compatible dApps
Approve blockchain transactions
Switch between supported networks
Manage supported wallet accounts
Review transaction requests
Available features depend on the MetaMask version, network, and supported assets.
For security, install MetaMask only through its official website or a verified browser extension store listing.
A typical installation process is:
Open your supported web browser.
Visit MetaMask's official website.
Follow the link to the appropriate browser extension.
Verify the extension publisher before installing.
Add the extension to your browser.
Open MetaMask and follow the wallet setup instructions.
Create a new wallet or restore an existing wallet through the official recovery process.
Avoid downloading wallet extensions from third-party websites or links sent through unsolicited messages.
When creating a new wallet, MetaMask provides a Secret Recovery Phrase that is essential for recovering wallet access.
Store this phrase securely and privately.
Never share your Secret Recovery Phrase or private keys with anyone. No legitimate support representative should ask you to provide your recovery phrase for verification, synchronization, or troubleshooting.
The MetaMask Extension can connect to compatible decentralized applications. When a dApp requests access, MetaMask presents a request that you can review.
Before approving a connection:
Verify the website address.
Confirm that you trust the application.
Check which account is being connected.
Review requested permissions.
Reject unexpected requests.
When signing or approving a transaction, carefully inspect the transaction details before confirming.
Because browser wallets interact with websites, phishing and malicious dApps can pose security risks.
For safer wallet management:
Install MetaMask only from official sources.
Keep your browser and MetaMask extension updated.
Use a strong wallet password.
Protect your Secret Recovery Phrase offline.
Never reveal private keys.
Avoid suspicious websites and unsolicited links.
Review every transaction before signing.
Be cautious of websites that claim your wallet is locked and ask you to enter your recovery phrase to restore access.
If MetaMask does not work correctly, first confirm that the extension was installed from an official source. Restart your browser and check whether updates are available.
For connection problems with a dApp, verify that the application supports MetaMask and that the correct network and account are selected.
Never install an unknown extension or provide your recovery phrase to someone claiming they can repair your wallet.

The MetaMask Extension provides a convenient way to access Web3 services, manage supported digital assets, and interact with decentralized applications through a browser. Safe usage starts with installing the authentic extension, protecting your Secret Recovery Phrase, checking dApp permissions, and reviewing transactions before approval.
