Available as a browser extension for Chrome, Firefox, Edge, and Brave, MetaMask® simplifies managing Ethereum-based assets and interacting with decentralized applications (DApps). This guide provides a step-by-step introduction to getting started with the MetaMask® extension.
1. Installing MetaMask® Extension
A. Downloading MetaMask®:
- Visit the Official Website: Go to the MetaMask® website to download the extension. It’s crucial to download MetaMask® from the official site to avoid phishing scams.

B. Setting Up MetaMask®:
- Open the Extension: Once installed, click on the MetaMask® icon in your browser’s toolbar.

- Secure Your Seed Phrase: After creating your wallet, MetaMask® will generate a 12-word seed phrase. This phrase is essential for recovering your wallet if you lose access. Write it down and store it in a safe place. Never share this phrase with anyone, as it provides full access to your wallet.
- Confirm Seed Phrase: MetaMask® will ask you to confirm your seed phrase to ensure you’ve recorded it correctly. Select the words in the correct order as prompted.
2. Navigating the MetaMask® Interface
A. Wallet Overview:
- Main Screen: After logging in, you’ll see your wallet’s main screen, which displays your Ethereum balance and any other Ethereum-based tokens you hold. The interface includes tabs for “Assets,” “Activity,” and “Browser.”
- Assets Tab: This tab shows the list of cryptocurrencies and tokens you own. You can view balances, send, and receive assets from this tab.
- Activity Tab: Here, you can review your transaction history, including recent sends and receives. This is useful for tracking your past transactions.
- Browser Tab: The DApp browser allows you to access various decentralized applications directly through MetaMask®. You can interact with DeFi platforms, NFT marketplaces, and more.
B. Adding and Managing Tokens:
- View Tokens: MetaMask® automatically displays popular tokens, but you can also add custom tokens. To do this, click “Add Token” and enter the token’s contract address, symbol, and decimal precision. This information can usually be found on the token issuer’s website or a blockchain explorer.
- Manage Tokens: You can view and manage your tokens in the “Assets” tab. Here, you can send, receive, and interact with various Ethereum-based assets.
3. Interacting with DApps
MetaMask® provides seamless integration with decentralized applications (DApps). Here’s how to use it:
- Connect to DApps: When you visit a DApp that supports MetaMask®, you’ll be prompted to connect your wallet. Click “Connect” and review the permissions requested by the DApp before approving the connection.
- Perform Transactions: Interacting with DApps often requires making transactions on the Ethereum network. MetaMask® will prompt you to confirm the transaction, including details such as gas fees. Review the information and click “Confirm” to proceed.
- Monitor Transactions: You can track the status of your transactions in the “Activity” tab. MetaMask® also provides links to blockchain explorers for more detailed transaction tracking.
