What Is MetaMask?

Why Use MetaMask?
MetaMask is widely used due to its simplicity, security, and compatibility with DeFi platforms, NFT marketplaces, and Web3 applications. It bridges users to the Ethereum blockchain without the need for a centralized exchange.
How to Set Up MetaMask
- Download MetaMask from the official website or your app store.
- Install the extension or app and click “Get Started”.
- Create a new wallet or import an existing one with your seed phrase.
- Set a strong password and store your seed phrase securely.
- Your wallet is ready to use with ETH and compatible tokens.
Key Features of MetaMask

Security Best Practices

Limitations of MetaMask
While powerful, MetaMask has limitations: it doesn’t support Bitcoin, transactions require gas fees, and being browser-based exposes it to certain risks if not used securely.
