Install

Install required dependencies for the project.

yarn install

Use node core modules in a RN project

In order to use non-React-Native dependencies, like crypto module, you'll need to follow the next step as React Native packager can't package node core modules.

yarn postinstall

Environment Variables

Create a .env file and add the following environmental variables:

Enter LTO API endpoint to get a detailed balance of your account with the format: .../addresses/balance/details/:

LTO_API_URL=

App receives info of LTO Network price on real time from Coinmarketcap API so you'll need to enter your CMC API key:

CMC_API_KEY=

The network you are going to use 'M' for mainnet and 'T' for testnet:

LTO_NETWORK_ID=

You also can refer to the .env.example file within the repository.

To run on Android/IOS

To run the project first configure SDK and sign the Android app (explained below). Once configured and as this is an expo ejected project, you can initialize it by running:

Android:

yarn react-native run-android

IOS:

yarn react-native run-ios

On both cases, metro bundler will start and will load the app.

Signing the Android app

To configure the signing you need to have the keystore.

keytool -genkey -v -keystore android/app/lto.keystore -alias lto -keyalg RSA -keysize 2048 -validity 10000

Follow this tutorial to configure gradle properties. You'll need to store the following env vars in $HOME/.gradle/gradle.properties or android/local.properties.

LTO_UPLOAD_STORE_FILE=lto.keystore
LTO_UPLOAD_KEY_ALIAS=lto
LTO_UPLOAD_STORE_PASSWORD=*****
LTO_UPLOAD_KEY_PASSWORD=*****

If you are using a mac, you can follow this article to see how to configure the mac keychain and prevent your keystore password to be stored in plain text.
