MetaMask Extension

A secure wallet and gateway to blockchain sites

Whether you are an experienced user or brand new to blockchain, MetaMask helps you connect to the decentralized web: a new internet.

We're trusted by millions of people across the world, and our mission is to make this new decentralized web accessible to all.

The MetaMask extension allows you to buy, send, spend, swap, and exchange your digital assets. Make pay
ments to anyone, anywhere. Customize your wallet with community-built Snaps. Log into websites securely to trade assets, lend, borrow, play games, publish content, buy rare digital art, and so much more.

With MetaMask, your keys and assets always stay in your control;
• Use MetaMask’s key vault, secure login and digital wallet to manage your digital assets.
• Generate passwords and keys on your phone and keep your accounts secure.
• Browse and connect to the decentralized websites.
• Control what information you share with the sites you use, and what to keep private.

If you’re already a MetaMask user, you can import your existing wallet. If you’re a new user, we'll help you get started!

Because MetaMask adds functionality to your traditional browser, we require permission to read and write to any webpage. You can always view our source code the way you would any Chrome extension, or on Github:
