DCore SDK for JVM

Set of APIs for accessing the DCore Blockchain.
If you are looking for other platforms you can find info below.

Requirements

Installation

Available through the JitPack.io

Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Add the dependency

dependencies {
    implementation 'com.github.DECENTfoundation:DCoreKt-SDK:$version_tag'
}

If not using gradle, check jitpack site for instructions.

Proguard rules

# DCore SDK
-keep class ch.decent.sdk.model.ObjectId

Usage

You can find example Android project with SDK usage here.

And example Java server project using the same SDK here.

You can find developer documentation for latest release here.

Use DCoreSdk to initialize the API. The DCoreApi provides different groups of APIs for accessing the blockchain and default configuration values.

The supported operations are located in ch.decent.sdk.model package, suffixed with Operation eg. TransferOperation(...). Use the BroadcastApi to apply the operations to DCore or use appropriate methods in APIs.

Access api using rest

import toChainObject
import okhttp3.OkHttpClient

// create API for HTTP
val api = DCoreSdk.createForHttp(OkHttpClient(), "https://testnet.dcore.io/")
// get account by name, resolves to account id '1.2.28'
val disposable = api.accountApi.get("public-account-10").subscribe { account ->
  account.id == "1.2.28".toChainObject()
}

Access api using websocket

import Credentials
import AssetAmount
import toChainObject
import okhttp3.OkHttpClient

// create API for websocket
val api = DCoreSdk.createForWebSocket(OkHttpClient(), "wss://testnet-socket.dcore.io/")
// create account credentials form account id and corresponding private key
val credentials = Credentials("1.2.28".toChainObject(), "5JMpT5C75rcAmuUB81mqVBXbmL1BKea4MYwVK6voMQLvigLKfrE")
// 1 DCT
val amount = AssetAmount(DCoreConstants.DCT.toRaw(1.toBigDecimal()))
// send to account '1.2.27' public-account-9
val disposable = api.accountApi.transfer(credentials, "1.2.27", amount).subscribe { trxConfirmation ->
  trxConfirmation.print()
}
