What is MetaMask Wallet?

The MetaMask Wallet is a versatile cryptocurrency wallet and gateway to blockchain applications that supports Ethereum and all Ethereum Virtual Machine (EVM) compatible networks. Developed by ConsenSys, it has become the most popular Web3 wallet with over 30 million monthly active users worldwide.

Available as a browser extension (primarily as MetaMask Chrome Extension) and mobile app, MetaMask® allows users to store cryptocurrencies, interact with decentralized applications (dApps), manage digital assets, and explore the growing world of decentralized finance (DeFi), NFTs, and the broader Web3 ecosystem.

Built-In Token Swapping

Getting Started with MetaMask Wallet

1 Download: Visit the official MetaMask.com website to begin the MetaMask Wallet download process for your preferred platform.

2 Install: Add the MetaMask Chrome Extension to your browser or install the mobile app from official app stores. The MetaMask wallet Extension appears as a fox icon in your browser toolbar.

3 Create Wallet: Set up a new wallet by creating a strong password and, most importantly, securely storing your 12-word secret recovery phrase. This phrase is essential for account recovery.

4 Secure Your Account: Complete your MetaMask login setup by understanding security best practices, including never sharing your recovery phrase and being cautious of phishing attempts.

5 Fund and Explore: Add cryptocurrency to your wallet and begin exploring dApps, DeFi platforms, NFT marketplaces, and other Web3 applications.

Security First: Your MetaMask® wallet is self-custodial, meaning you alone control your funds and are responsible for their security. Always download from official sources and never share your recovery phrase with anyone.

Platform Availability

MetaMask® offers multiple access points to suit different user preferences and needs:

All platforms maintain feature parity where possible, with the browser extension offering the most comprehensive dApp interaction capabilities and the mobile app providing convenience for on-the-go access and transactions.

Frequently Asked Questions

Is MetaMask Wallet completely free to use?
Yes, MetaMask® is free to download and use. However, you will need to pay blockchain network fees (gas fees) for transactions, and the integrated swap service may include a small percentage-based fee for exchanges.
Can I use the same wallet on both mobile and browser extension?
Yes, you can access the same wallet across multiple devices by importing it using your secret recovery phrase. This allows you to manage your assets seamlessly whether you're using the mobile app or browser extension.
What happens if I lose my secret recovery phrase?
If you lose your recovery phrase, there is no way to recover your wallet or funds. MetaMask® is a non-custodial wallet, meaning only you have access to your recovery phrase, and there's no password reset option.
How secure is MetaMask compared to hardware wallets?
While MetaMask® implements strong security measures, it's a "hot wallet" connected to the internet, making it potentially less secure than hardware ("cold") wallets. For large holdings, consider connecting a hardware wallet to MetaMask® for enhanced security.
Can I buy cryptocurrency directly in MetaMask?
Yes, MetaMask® offers integrated buying options through trusted partners like Wyre and Transak, allowing you to purchase crypto with traditional payment methods directly within the wallet interface.
Does MetaMask support Bitcoin or other non-EVM cryptocurrencies?
MetaMask® primarily supports Ethereum and EVM-compatible chains. It doesn't natively support Bitcoin or other non-EVM cryptocurrencies, though wrapped versions of these assets (like WBTC) can be held and managed.
