The MetaMask Extension is a browser-based wallet that allows users to interact with supported blockchain networks and Web3 applications. Through the extension, users can manage wallet accounts, view supported digital assets, connect to decentralized applications, and review transaction requests.
MetaMask is a self-custodial wallet that gives users control over their wallet accounts and assets. Its browser extension provides a convenient interface for interacting with compatible decentralized applications directly from a web browser.
Because MetaMask is self-custodial, users are responsible for protecting their Secret Recovery Phrase and private keys.
To begin using the extension:
Use a supported, up-to-date browser.
Obtain MetaMask through an official MetaMask source or verified browser-extension marketplace listing.
Install and open the extension.
Create a new wallet or use the supported recovery process for an existing wallet.
Follow the setup instructions carefully.
Review connection, signature, and transaction requests before approving them.
Connect MetaMask to compatible decentralized applications and blockchain services.
View supported accounts and assets through the extension interface.
Review transaction details before approving an action. When possible, verify important information carefully before signing.
MetaMask supports multiple blockchain networks, with available networks and features depending on the current software version and configuration.
Your Secret Recovery Phrase is highly sensitive information.
Never share it with anyone. Never enter it into a website, online form, email, chat message, or unsolicited support request.
Your Secret Recovery Phrase and private keys should remain under your control. Anyone who obtains them may potentially gain access to the associated wallet.
Fraudulent browser extensions and websites can imitate MetaMask. Before installing an extension, verify the official source and publisher carefully.
Do not install wallet extensions from unknown websites or follow installation links received through unsolicited messages or advertisements.
Before connecting MetaMask to a decentralized application, verify that the website is legitimate and that you understand the requested permissions.
Pay special attention to token approvals, signatures, and transaction requests. Do not approve an unfamiliar request simply because a website claims it is required to unlock, verify, or secure your wallet.
If the extension is not functioning correctly, ensure that your browser and MetaMask installation are updated through official sources. Consult official MetaMask support documentation for troubleshooting steps.
Never provide your Secret Recovery Phrase or private keys to someone claiming to offer technical support.
