An online digital wallet that allows users to manage, transfer and receive Ethereum, operating as an extension to a regular browser.
The cryptocurrency wallet was created in 2016 by ConsenSys, a Brooklyn-based blockchain software company focusing on Ethereum-related tools and infrastructure.

Due to its success in the cryptocurrency community, the lack of an official mobile website for several years led to malicious actors to develop phishing software that posed as MetaMask’s mobile app.
