The MetaMask Extension is a browser-based cryptocurrency wallet that lets users manage supported blockchain accounts and interact with decentralized applications (dApps). It provides a convenient way to connect a wallet to compatible websites while keeping control of wallet credentials with the user.
MetaMask is a self-custodial wallet. The browser extension can be used to view supported assets, manage accounts, connect to dApps, and approve blockchain transactions.
Unlike a traditional online account, MetaMask does not rely on a central service to hold your wallet's private keys. Users are responsible for protecting their wallet password, private keys, and Secret Recovery Phrase.
For a secure installation:
Start from the official MetaMask website.
Follow the official link to the supported browser extension store.
Verify the publisher and extension details before installing.
Add the extension to your browser.
Open MetaMask and follow the setup instructions.
Create a new wallet or restore an existing wallet using the appropriate official process.
Avoid downloading browser extensions from unofficial websites or links sent through unsolicited messages.
After installation, MetaMask can be used to:
View supported cryptocurrency balances.
Manage wallet accounts.
Connect to compatible dApps.
Review website connection requests.
Approve or reject transaction requests.
Interact with supported blockchain networks.
Always review requests carefully before approving them.
Your Secret Recovery Phrase is the most important piece of wallet recovery information. Anyone who obtains it may be able to restore your wallet and control its assets.
Never share your Secret Recovery Phrase or private keys. Do not enter them into websites, forms, emails, chats, or messages claiming to provide support.
Keep your MetaMask password private and use appropriate device security.
Fraudulent browser extensions can imitate MetaMask and attempt to collect wallet credentials. Before installing an extension, verify that you reached it through an authentic MetaMask source and carefully check the extension publisher.
Avoid extensions promoted through suspicious advertisements, unsolicited messages, or unfamiliar download sites.
Only connect your MetaMask wallet to websites you recognize and trust. Before approving a connection or transaction, review the requested permissions and transaction details.
A website connection and a transaction approval are different actions, so consider each request independently.
If the extension is not working correctly, make sure your browser and MetaMask installation are current and consult official MetaMask support resources.
Never follow troubleshooting instructions that ask you to reveal your Secret Recovery Phrase or private keys.
The MetaMask Extension can make Web3 interactions more convenient, but users remain responsible for protecting their wallet credentials. Using the authentic extension, checking dApp permissions, and carefully reviewing transactions can help reduce common security risks.
Never give your Secret Recovery Phrase to anyone, including someone claiming to be MetaMask support.
