Technical Setup and Configuration
The UpChain Wallet project is built using Android Studio. To configure the development environment, you need to create a local.properties file with the following variables:
sdk.dir: This should point to your local Android SDK directory.gpr.user&gpr.key: These credentials are used for accessing certain package repositories.infura.key: An API key from Infura is required for the wallet to communicate with the Ethereum blockchain network.
An Infura key can be obtained for free by signing up on their official website.
