Your Gateway to the Decentralized Web
MetaMask is a cryptocurrency wallet and gateway to blockchain apps. It allows users to access their Ethereum wallet through a browser extension or mobile app, which can then interact with decentralized applications.
MetaMask is a software cryptocurrency wallet used to interact with the Ethereum blockchain. It allows users to store and manage account keys, broadcast transactions, send and receive Ethereum-based cryptocurrencies and tokens, and securely connect to decentralized applications through a compatible web browser or the mobile app's built-in browser.
As a non-custodial wallet, MetaMask gives users full control over their funds and private keys, which are stored locally on their device rather than with a centralized exchange or wallet provider.
When you encounter a website that supports MetaMask login, the process typically involves:
This authentication method eliminates the need for traditional usernames and passwords, replacing them with cryptographic proof of ownership.
Install the extension, create a wallet, and you're ready to explore Web3
Connect to Ethereum, Polygon, Binance Smart Chain, and other networks
View and manage all your Ethereum-based tokens in one place
Built-in browser for exploring decentralized applications on mobile
While MetaMask provides a secure way to interact with blockchain applications, users should follow these security best practices:
Your 12-word seed phrase is the master key to your wallet. Never share it with anyone and store it securely offline. Anyone with your seed phrase can access all your funds.
Only connect your wallet to trusted websites. Check URLs carefully to avoid phishing sites that mimic legitimate dApps.
Always carefully review transaction details, amounts, and gas fees before confirming any transaction in MetaMask.
Regularly update your MetaMask extension or app to ensure you have the latest security patches and features.
