MetaMask Chrome Extension — Complete Guide | MetaMask Official

Overview

The MetaMask Chrome Extension is a secure, user-friendly cryptocurrency wallet and gateway to blockchain applications. This guide will help users install, set up, and optimize their MetaMask experience for managing Ethereum, tokens, and interacting with decentralized apps (dApps).

MetaMask combines convenience with security, allowing users to store, send, and receive cryptocurrency directly from their browser, while keeping private keys safely encrypted and offline.

Throughout this guide, we will cover step-by-step instructions, essential tips, and best practices to get the most out of your MetaMask wallet.

Installation

Step 1: Open Chrome Web Store

Visit the Chrome Web Store and search for "MetaMask." Ensure that you are downloading the official MetaMask extension to avoid phishing scams.

Step 2: Add Extension to Chrome

Click on “Add to Chrome” and follow the on-screen instructions. Once installed, the MetaMask icon will appear in the top-right corner of your Chrome browser.

Step 3: Confirm Installation

Click the MetaMask icon to confirm that the extension is installed correctly. You will be prompted to either create a new wallet or import an existing one.

Wallet Setup

Step 1: Create a New Wallet

Click “Create a Wallet”. You will be asked to set a strong password for your MetaMask extension.

Step 2: Backup Your Secret Recovery Phrase

MetaMask will provide a 12-word Secret Recovery Phrase. Write this down securely offline. It is essential for recovering your wallet in case of device loss or password reset.

Step 3: Confirm Recovery Phrase

Verify your Secret Recovery Phrase by selecting the words in the correct order. This step ensures you have backed up your phrase correctly.

Step 4: Finalize Setup

Once confirmed, your wallet setup is complete. You can now receive, send, and manage Ethereum and ERC-20 tokens directly from Chrome.

Using MetaMask

Sending and Receiving Tokens

To send tokens, click “Send,” enter the recipient’s address, choose the token type, and confirm. To receive, copy your wallet address and share it securely.

Connecting to dApps

MetaMask allows seamless interaction with decentralized applications. Click “Connect” on supported websites to authorize access to your wallet for transactions.

Managing Multiple Accounts

Create and switch between multiple accounts for different purposes. Each account has its own address and balance while being part of the same MetaMask extension.

Custom Tokens

Add custom tokens by entering the contract address, token symbol, and decimal precision. This enables tracking tokens not automatically listed in MetaMask.

Security Tips

Keep Recovery Phrase Safe

Never store your Secret Recovery Phrase digitally. Use secure offline storage to prevent unauthorized access.

Enable Phishing Protection

MetaMask warns you of potentially malicious websites. Always double-check URLs and avoid entering wallet credentials on unknown sites.

Strong Passwords

Use a unique, complex password for MetaMask. Avoid reusing passwords from other accounts.

Two-Factor Authentication

Although MetaMask does not directly support 2FA, securing your Google account and browser with 2FA adds an extra layer of protection.

Advanced Features

Hardware Wallet Integration

MetaMask can connect with Ledger and Trezor devices for enhanced security. Transactions are signed via hardware devices while keeping private keys offline.

Custom Networks

Add custom networks like Binance Smart Chain or Polygon to interact with non-Ethereum dApps. Input RPC URL, chain ID, and symbol.

Token Swaps

MetaMask allows token swaps directly within the extension, providing best price routes and low fees.

Analytics & Activity

Track your transaction history, monitor gas fees, and analyze wallet activity for better management of your assets.
