MetaMask Wallet Extension™

An Ethereum Wallet in your Browser. MetaMask is an extension for accessing Ethereum enabled distributed applications, or "Dapps" in your browser! Watch an introductory video here..

MetaMask lets you create and manage your own identities (via private keys, local client wallet and hardware wallets like Trezor™). When a Dapp wants to perform a transaction and write to the blockchain, you get a secure interface to review that transaction before approving or rejecting it.

What is Metamask?

Metamask is a cryptocurrency wallet and gateway to blockchain applications available as a browser extension for Chrome, Firefox, and other compatible browsers. Developed initially as a simple Ethereum wallet, Metamask has evolved into a versatile tool that allows users to manage their Ethereum assets, interact with decentralized applications (dApps), and participate in blockchain-based protocols and smart contracts.
