MetaMask gives you an Ethereum Wallet to buy, spend, send, and exchange digital assets from your browser and Android device.

The MetaMask extension injects the Ethereum web3 API into every website's javascript context so that DApps can read from the blockchain. It also lets you create and manage identities (via private keys, local client wallets, and other hardware wallets like Trezor). When a DApp wants to perform a transaction and write to the blockchain, you get a secure interface to review the transaction before approving or rejecting it.

MetaMask allows you to make payments to anyone, anywhere. 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 desktop user, the app will sync your existing wallet in seconds.

MetaMask is adding a Bank and PayPal feature allowing you to withdraw to Fiat. This integration will make is so much more usable to the masses.

As with any investment app, you should be vigilant with your security protocols for the device where it is installed. Use MetaMask at your own risk.
