Related: ledger-live-desktop

Ledger Live is a mobile companion app for Ledger hardware wallets. It allows users to manage their crypto assets securely, such as Bitcoin, Ethereum, XRP and many others. Ledger Live mobile is available for iOS and Android.

Architecture

Ledger Live is a native mobile application built with React Native, React, Redux, RxJS,.. and some native libraries. The architecture is analog to the desktop application and also uses our C++ library, the lib-ledger-core to deal with blockchains (sync, broadcast,..) via ledger-core-node-bindings. It communicates to the brand new Ledger Nano X via Bluetooth to manage installed applications, to update the device firmware, to verify public addresses and to sign transactions with ledgerjs. We also share some logic with live-common.

Developing on ledger-live-mobile

Pre-requisites

Node LTS version
Yarn 1.10.1 or above

iOS

XCode

Android

Android Studio

Scripts

`yarn install`

install dependencies.

`yarn start`

Runs your app in development mode.

Sometimes you may need to reset or clear the React Native packager's cache. To do so, you can pass the --reset-cache flag to the start script:

yarn start -- --reset-cache

`yarn test`

`yarn run ios`

or open ios/ledgerlivemobile.xcodproj

`yarn run android`

or open android/ in Android Studio.

Environment variables

Optional environment variables you can put in .env, .env.production or .env.staging for debug, release, or staging release builds respectively.

DEVICE_PROXY_URL=http://localhost:8435   # enable a dev mode to use the device over HTTP. use with https://github.com/LedgerHQ/ledgerjs/tree/master/packages/hw-http-proxy-devserver
BRIDGESTREAM_DATA=...       # come from console.log of the desktop app during the qrcode export. allow to bypass the bridgestream scanning
DEBUG_RNDEBUGGER=1          # enable react native debugger
DISABLE_READ_ONLY=1         # disables readonly mode by default

Maintenance

Refresh the flow-typed from flow-typed Github

yarn sync-flowtyped

Refresh the languages (when we add new languages)

yarn sync-locales

Troubleshooting

XCode 10

When trying to build with XCode 10 and React Native v0.57.0, you might have issues with third party packages from React Native. To solve this issue you must:

./node_modules/react-native/scripts/ios-install-third-party.sh

The build on XCode 10 should then work.
