MetaMask Wallet - Complete Guide to Secure Web3 Access

It allows users to access their wallets through a browser extension or mobile app, which can then be used to interact with decentralized applications (dApps).

Frequently Asked Questions

Is MetaMask free to use?

Yes, MetaMask® is completely free to download and use. The only costs associated are standard blockchain network fees (gas fees) for transactions, which are paid to network validators, not to MetaMask®.

Can I use MetaMask on multiple devices?

Yes, you can use your MetaMask® wallet on multiple devices by importing it using your secret recovery phrase. Your wallet data is stored on the blockchain, so you can access it from any compatible device with your recovery phrase.

What's the difference between the extension and mobile app?

The browser extension is designed for desktop use and integrates directly with your web browser to interact with dApps. The mobile app provides similar functionality with the addition of a built-in dApp browser for mobile devices.

How do I add custom networks to MetaMask?

You can add custom networks by going to Settings > Networks > Add Network. You'll need to provide the network details including Network Name, RPC URL, Chain ID, Currency Symbol, and Block Explorer URL.

What should I do if I forget my MetaMask password?

If you forget your password, you can reset it using your secret recovery phrase. Your password only protects access to the extension on that specific device, while your recovery phrase controls access to your actual wallet on the blockchain.
