MetaMask Extension

Securely manage Ethereum, ERC-20 tokens, and decentralized apps directly from your browser with MetaMask.

Introduction to MetaMask Extension

The MetaMask Extension is a browser-based wallet that enables users to securely store, send, and receive Ethereum and ERC-20 tokens. It also allows interaction with decentralized applications (dApps) and blockchain platforms directly from your browser.

Unlike web wallets that store private keys online, MetaMask keeps keys encrypted locally, giving you full control over your funds. The extension supports Chrome, Firefox, Edge, and Brave, providing a reliable and convenient interface for crypto enthusiasts.

Why MetaMask Extension?

Full Control of Private Keys

Your private keys are stored locally on your device. Only you have access, ensuring maximum security.

Seamless dApp Access

Directly connect to decentralized apps without third-party intermediaries. MetaMask Extension is widely compatible with Ethereum-based applications.

Encrypted Transactions

Each transaction must be manually approved in the extension. This prevents unauthorized transfers and enhances security.

Installation Steps

Step 1: Download from Official Source

Visit the official MetaMask website or your browser’s extension store. Only download from verified sources to avoid phishing or fraudulent copies.

Step 2: Install Extension

Follow the installation prompts for your browser. Once installed, a fox icon will appear in the browser toolbar.

Step 3: Create or Import Wallet

Open the extension and select “Create a new wallet” to generate a new account or “Import wallet” to restore an existing one using a recovery phrase.

Step 4: Set a Strong Password

Set a secure password for the extension. This password is required to unlock your wallet during sessions.

Step 5: Backup Recovery Phrase
