What is MetaMask Extension?

MetaMask® Extension is a browser-based cryptocurrency wallet that allows users to interact with the Ethereum blockchain and other compatible networks. It serves as both a wallet for storing cryptocurrencies and a gateway to decentralized applications (dApps) in the Web3 ecosystem.

Unlike traditional wallets, MetaMask® operates as a browser extension, providing seamless access to blockchain functionalities without needing to run a full node. Your private keys are stored securely in your browser and encrypted with a password you create.

Frequently Asked Questions

Is MetaMask® Extension free to use?
Yes, MetaMask® is completely free to download and use. However, blockchain transactions still require paying network fees (gas fees) to process transactions.
Can I use MetaMask® on multiple browsers?
Yes, you can install MetaMask® on multiple browsers, but you'll need to set up each installation separately or import your wallet using your seed phrase.
How do I recover my MetaMask® wallet if I lose access?
You can recover your wallet using your secret recovery phrase (seed phrase). This is why it's crucial to store your seed phrase securely and never share it with anyone.
What cryptocurrencies are supported in MetaMask®?
MetaMask® primarily supports Ethereum and ERC-20 tokens. However, by adding custom networks, you can use it with other compatible blockchains like Binance Smart Chain, Polygon, Avalanche, and more.
Is my crypto stored in the MetaMask® extension?

Important Security Note: Always ensure you are downloading MetaMask® from official sources like the Chrome Web Store or directly from metamask.io. Beware of phishing sites and fake extensions. Never share your seed phrase with anyone, and always verify transaction details before confirming.
