What is MetaMask®?

MetaMask® is a software cryptocurrency wallet used to interact with the Ethereum blockchain and other compatible networks. It allows users to access their crypto assets and decentralized applications (dApps) through a browser extension or mobile app. As a non-custodial wallet, MetaMask® gives you complete control over your private keys and funds—you are your own bank.

Initially launched as a MetaMask Chrome Extension, it now supports all major browsers including Firefox, Brave, and Edge. The MetaMask Wallet mobile app brings the same functionality to iOS and Android devices, enabling you to manage your digital assets on the go.

Key Features of MetaMask®

Frequently Asked Questions (FAQs)

Is MetaMask® Wallet free to use?

Do I need the MetaMask Extension if I have the mobile app?

What happens if I lose my device or uninstall the extension?

While primarily designed for Ethereum, MetaMask® supports any Ethereum-compatible blockchain network like Polygon, Binance Smart Chain, Avalanche, and many others through custom network settings.

How do I ensure my MetaMask® wallet remains secure?

Always download from official sources, never share your recovery phrase, use strong passwords, enable automatic updates, be cautious of phishing sites, and consider connecting to a hardware wallet for additional security.
