Zap is a free Lightning Network wallet focused on user experience and ease of use, with the overall goal of helping the cryptocurrency community scale Bitcoin and other cryptocurrencies.

Zap is built on top of [LND](https://github.com/lightningnetwork/lnd),
uses a [Node.js](https://github.com/LN-Zap/zap-nodejs) proxy and,
[Electron](https://electron.atom.io/) + [React](https://facebook.github.io/react/) + [Redux](https://github.com/reactjs/redux/tree/master/docs) for the UI.
