CrowdNode Node.js SDK

CrowdNode allows you to become a partial MNO - staking Dash to earn interest, participate in voting, etc.

The CrowdNode Node.js SDK enables you to build Web-based flows and cross-platform CLI tools to privately manage staking using CrowdNode's KYC-free Blockchain API.

Install

Node.js

You must have node.js installed:

Mac & Linux

curl https://webinstall.dev/node | bash
export PATH="${HOME}/.local/opt/node:$PATH"

Windows

curl.exe -A MS https://webinstall.dev/node | powershell
PATH %USERPROFILE%\.local\opt\node;%PATH%

CrowdNode SDK

npm install --save crowdnode@v1

(async function () {
  let dashsight = window.DashSight.create({
    baseUrl: "https://insight.dash.org",
  });

  // ...

  await window.DashSocket.listen(
    "https://insight.dash.org",
    function finder(evname, data) {
      console.log(evname, data);
    },
    { debug: true },
  );
})();

API

The SDK also provides Type Hinting via JSDoc (compatible with TypeScript / tsc without any transpiling).

IMPORTANT

The CLI is denominated in Dash and Percent because those are the units most customers are familiar with and can easily calculate in their heads without making "careless" mistakes.

HOWEVER, the SDK and CrowdNode API are denominated in Duffs (Satoshis) and Permil (Permille) because those are the whole units that are easiest to compute.

QuickStart

The CrowdNode SDK uses Dashcore to create raw transactions and broadcasts them as Instant Send via the Dash Insight API. It uses Dash Insight WebSockets to listen for responses from the CrowdNode hotwallet.

A simple CrowdNode application may look like this:

"use strict";

let Fs = require("fs").promises;
let CrowdNode = require("crowdnode");

async function main() {
  let keyfile = process.argv[2];

  // a wallet pre-loaded with about Đ0.01
  let wif = await Fs.readFile(keyfile, "utf8");
  wif = wif.trim();

  // Initializes API info, such as hotwallets
  await CrowdNode.init({ insightBaseUrl: "https://insight.dash.org/" });

  let hotwallet = CrowdNode.main.hotwallet;
  await CrowdNode.signup(wif, hotwallet);
  await CrowdNode.accept(wif, hotwallet);
  await CrowdNode.deposit(wif, hotwallet);

  console.info("Congrats! You're staking!");
}

main().catch(function (err) {
  console.error("Fail:");
  console.error(err.stack || err);
  process.exit(1);
});

There are also a number of utility functions which are not exposed as public APIs, but which you could learn from in crowdnode-cli.

Constants

CrowdNode.offset = 20000;
CrowdNode.duffs = 100000000;
CrowdNode.depositMinimum = 10000;

CrowdNode.requests = {
  acceptTerms: 65536,
  offset: 20000,
  signupForApi: 131072,
  toggleInstantPayout: 4096,
  withdrawMin: 1,
  withdrawMax: 1000,
};

CrowdNode.responses = {
  PleaseAcceptTerms: 2,
  WelcomeToCrowdNodeBlockChainAPI: 4,
  DepositReceived: 8,
  WithdrawalQueued: 16,
  WithdrawalFailed: 32,
  AutoWithdrawalEnabled: 64,
  AutoWithdrawalDisabled: 128,
};

Usage

Manage Stake

 */

// permil is 1/10 percent, 500 permil = 50.0 percent
await CrowdNode.withdraw(wif, hotwallet, permil);
/** @type SocketPayment
 * {
 *   "address": "Xj00000000000000000000000000000000",

HTTP RPC

await CrowdNode.http.GetBalance(pubAddr);
/** @type CrowdNodeBalance

 * }
 */

await CrowdNode.http.GetFunds(pubAddr);
await CrowdNode.http.GetFundsFrom(pubAddr, secondsSinceEpoch);
/*
 *  [

await CrowdNode.http.IsAddressInUse(pubAddr);
/**

 */

Messages (Voting, etc)

await CrowdNode.http.GetMessages(pubAddr);
/**
 * []
 */

await CrowdNode.http.SetEmail(wif, email, sig);
await CrowdNode.http.Vote(wif, gobjectHash, vote, sig);
await CrowdNode.http.SetReferral(wif, referralId, sig);

await CrowdNode.http.FundsOpen(pub);
