MetaMask (which, like an editorially independent Decrypt, is funded by Ethereum incubator ConsenSys) is a browser plugin that serves as an Ethereum

wallet, and is installed like any regular plugin. Once it’s installed, it allows users to store Ether and other ERC-20 tokens, enabling them to make transactions to any Ethereum address.
