WalletSDK

This is an SDK to use the system-level wallet on ethOS.

How to add the WalletSDK into your app

First, go into your settings.gradle file and add the line maven { url 'https://jitpack.io' } to the pluginManagement and the dependencyResolutionManagement section like this:

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

Then go to your module-level build.gradle file and add the following line to the dependencies section:

// Web3j needed for the WalletSDK
implementation 'org.web3j:core:4.8.8-android'
implementation 'com.github.EthereumPhone:WalletSDK:0.0.10'

How to initialize SDK

// You just need to supply a context
val wallet = WalletSDK(context)

// You can also supply your own web3j instance, like this:

val web3j = Web3j.build(HttpService("https://rpc.ankr.com/eth"))
val wallet = WalletSDK(
    context = context,
    web3RPC = web3j
)

How to sign a message

// How to sign Message
CoroutineScope(Dispatchers.IO).launch {
    val result = wallet.signMessage(
        message = "Message to sign"
    )
    println(result)
}

How to send a Transaction

CoroutineScope(Dispatchers.IO).launch {
    val result = wallet.sendTransaction(
        to = "0x3a4e6ed8b0f02bfbfaa3c6506af2db939ea5798c", // mhaas.eth
        value = "1000000000000000000", // 1 eth in wei
        data = "")
    println(result)
}
