MetaMask® Crypto Wallet™ Chrome Extension®
Welcome to the world of decentralized access with the MetaMask Crypto Wallet™ Chrome Extension® — one of the most widely used browser-based wallets for interacting with blockchain networks, decentralized applications (dApps), NFTs, and digital assets.
MetaMask transforms your Chrome browser into a secure Web3 gateway, allowing you to store, send, swap, and manage cryptocurrencies while maintaining full control of your private keys. Built for both beginners and experienced crypto users, MetaMask combines accessibility with powerful blockchain functionality.
🌐 What Is MetaMask Chrome Extension?
MetaMask Chrome Extension is a browser-based cryptocurrency wallet that enables users to:
- Store Ethereum and compatible tokens
- Connect to decentralized applications
- Interact with DeFi protocols
- Manage NFTs

As a non-custodial wallet, MetaMask ensures that users — not centralized platforms — control private keys and digital assets.
🔐 Non-Custodial Security & User Control
Security is the foundation of MetaMask’s architecture.
Private Key Ownership
Your private keys are encrypted and stored locally on your device. MetaMask does not store your keys on centralized servers.
Secret Recovery Phrase
When creating a wallet, users receive a 12-word Secret Recovery Phrase. This phrase allows wallet restoration if your device is lost or replaced.
Password Protection
Access to your wallet requires a secure password set during setup.
Transaction Approval
Every blockchain interaction must be confirmed manually, providing transparency and protection against unauthorized activity.
Because MetaMask is non-custodial, you are solely responsible for safeguarding your recovery phrase and device security.
