The original web3 wallet
Wallet Type: Web3 wallet: Extensions available for Chrome, Firefox, Opera and more​
Description: MetaMask is the original web3 wallet. It allows you to run Ethereum dApps right in your browser without running a full Ethereum node. See our Metamask Setup instructions to start using with xDai.
Nifty Wallet and MetaMask do not function properly when both are activated at the same time as chrome extensions. To use one or the other, right click on the extension icon, go to Manage Extensions, and toggle off/on the application you want to use. All data will be preserved in the wallet for future access.
