Ledger Live is a new generation wallet desktop application providing a unique interface to maintain multiple cryptocurrencies for your Ledger Nano S / Blue. Manage your device, create accounts, receive and send cryptoassets, ...and many more.
Ledger Live is an hybrid desktop application built with Electron, React, Redux, RxJS,.. and highly optimized with ledger-core C++ library to deal with blockchains (sync, broadcast,..) via ledger-core-node-bindings. It communicates to Ledger hardware wallet devices (Nano S / Blue) to verify address and sign transactions with ledgerjs. Some logic is shared with live-common.
- supported by ledger-core (C++) implementation: BTC BCH LTC DASH QTUM ZEC BTG STRAT DOGE DGB HSR KMD PIVX ZEN VTC PPC VIA XST POSW CLUB
- supported by JavaScript implementation: ETH, ETC, XRP
- NodeJS LTS
- Yarn LTS
- Python v2.7.10 (used by node-gyp to build native addons)
- You will also need a C++ compiler
- In the application we use
Museo Sansfont. To include it in the app, you need to have a zip filemuseosans.zipwhich you should extract and place inside thestatic/fonts/museosansdirectory
# install dependencies
yarn# launch the app
yarn start# Build & package the whole app
# Creates a .dmg for Mac, .exe installer for Windows, or .AppImage for Linux
# Output files will be created in dist/ folder
yarn distNote: Use yarn dist:dir to speed up the process: it will skip the packaging step. Handy for debugging builds. You can also use BUNDLE_ANALYZER=1 yarn dist:dir to generate webpack-bundle-analyzer report.
(you can use a .env or export environment variables)
