DCore SDK for JS

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



npm install --save rxjs
npm install --save dcorejs-sdk

Make sure you import reflect-metadata in an entry class to your application, eg. import "reflect-metadata";

To enable debug logging you can use rxjs-spy.


You can find example project with SDK usage 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.operation 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 "reflect-metadata";
import { DCoreSdk } from "dcorejs-sdk";

// create the API
const api = DCoreSdk.createForHttp({ baseUrl: "" })
// get account by name, resolves to account id '1.2.27'
const disposable = api.accountApi.get("public-account-9")
    .subscribe((account) => console.log(;

Access api using websocket. We need to install some websocket library beforehand if we are not running in the browser. Eg. npm install --save ws

import "reflect-metadata";
import { AssetFormatter, ChainObject, Credentials, DCoreSdk } from "dcorejs-sdk";
import { create } from "rxjs-spy";
import * as WebSocket from "ws";

// debug logging: init rxjs-spy and log all tags
const spy = create();

// create api for websocket
const api = DCoreSdk.createForWebSocket(() => new WebSocket("wss://"));
// create account credentials
const credentials = new Credentials(ChainObject.parse("1.2.27"), "5Hxwqx6JJUBYWjQNt8DomTNJ6r6YK8wDJym4CMAH1zGctFyQtzt");
// send 1DCT to account id '1.2.28 (public-account-10)' with encrypted 'hello memo' memo
const disposable = api.accountApi.transfer(credentials, "public-account-10", AssetFormatter.DCT.amount(1), "hello memo")
    .subscribe((confirmation) => console.log(;
