Build a Desktop Wallet in JavaScript

·

This tutorial demonstrates how to build a desktop wallet for the XRP Ledger using:

👉 Get started with XRP Ledger development

Prerequisites

Source Code

The complete source code is available in the XRPL Dev Portal repository.

npm install  
npm run ledger-index

Goals

By the end, you'll build a wallet capable of:

✅ Real-time ledger updates
✅ Read-only account monitoring
✅ Sending XRP payments with destination address validation
✅ Domain verification checks

Step-by-Step Implementation

1. Project Setup

Initialize the project with package.json:

{
  "name": "xrpl-javascript-desktop-wallet",
  "scripts": {
    "start": "electron ./index.js"
  },
  "dependencies": {
    "xrpl": "^3.0.0",
    "electron": "22.3.24"
  }
}

2. Connect to XRP Ledger

const xrpl = require("xrpl");
const TESTNET_URL = "wss://s.altnet.rippletest.net:51233";

async function getLedgerIndex() {
  const client = new xrpl.Client(TESTNET_URL);
  await client.connect();
  const ledger = await client.request({ "command": "ledger" });
  return ledger.result.ledger_index;
}

3. Display Real-Time Updates

Subscribe to ledger events:

await client.request({
  "command": "subscribe",
  "streams": ["ledger"]
});

client.on("ledgerClosed", (ledger) => {
  console.log("New ledger:", ledger.ledger_index);
});

4. Send XRP Payments

const paymentTx = {
  "TransactionType": "Payment",
  "Account": wallet.address,
  "Amount": xrpl.xrpToDrops("10"),
  "Destination": "rPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe"
};

const signed = wallet.sign(paymentTx);
await client.submitAndWait(signed.tx_blob);

FAQ
