MetaMask is a bridge that allows you to visit the distributed web of tomorrow in your browser today. It allows you to run Ethereum dApps right in your browser without running a full Ethereum node.
MetaMask includes a secure identity vault, providing a user interface to manage your identities on different sites and sign blockchain transactions.
We’re initially building MetaMask as a Chrome extension, but eventually plan to support Firefox and beyond. If you’re a developer, you can start developing with MetaMask today.
Our mission is to make Ethereum as easy to use for as many people as possible.
