MetaMask Chrome Extension is a widely used crypto wallet that runs directly in your browser and enables access to blockchain applications, decentralized finance (DeFi), and NFT platforms. It allows users to store tokens, connect to Web3 sites, and manage digital assets securely without relying on centralized exchanges.

It is commonly used with Google Chrome and other Chromium-based browsers and is one of the most popular tools for interacting with Web3 applications.

What is MetaMask Chrome Extension?

The MetaMask Chrome Extension is a non-custodial wallet, meaning you fully control your private keys. It acts as a bridge between your browser and blockchain networks such as Ethereum and compatible chains.

Once installed, it lets you:

• Create or import crypto wallets

• Store tokens and NFTs

• Connect to decentralized applications (dApps)

• Sign blockchain transactions securely

Unlike exchange wallets, MetaMask does not hold your funds—it gives you direct control over your assets.

Key Features of MetaMask Extension

1. Web3 Access

Connect instantly to decentralized apps such as DeFi platforms, NFT marketplaces, and blockchain games.

2. Multi-Network Support

Supports Ethereum and other compatible networks like Polygon, BNB Chain, and more.

3. Token Management

Add, send, and receive tokens directly from your browser wallet.

4. Secure Transaction Signing

Every transaction must be manually confirmed inside the extension.

5. Wallet Import & Backup

Restore wallets using a 12-word secret recovery phrase.

How MetaMask Chrome Extension Works

MetaMask operates inside your browser as a secure wallet environment:
