Transfer of Ethers between accounts

Transfer of Ethers between accounts


In this section, we will guide you through the creation of an application that:

  • creates a transaction
  • signs it using the Ledger Nano then
  • sends it to the blockchain.

The purpose of the application is to transfer ethers from your ethereum account on your Ledger to another account.

Tutorial Prerequisites

Before starting, make sure you have gone through the prerequisites.

Receive Ether token in your Ledger Nano Ethereum Sepolia account

  • Create an Ethereum Sepolia account in Ledger Live
  • Send Sepolia Eth to your account with Infura faucet (opens in a new tab). You will need to create an account that will be useful later for the API key.

Tutorial implementation

In this implementation, we will be building a web application with vanilla javascript that uses the HID protocol from a Ledger package (opens in a new tab) to communicate with the ledger.

Project Initialization

It is time to implement the application and test it. First, open a terminal and create a new folder. For this tutorial, the folder will be named "e2e-eth-tutorial”. Run:

mkdir e2e-eth-tutorial
cd e2e-eth-tutorial

Initialize the project by running the following:

npm init

Answer the questions displayed or by default press enter. There is no incidence on the execution.


touch index.html
touch index.js
touch style.css
mkdir assets

Copy the logo in the assets folder.

The folder will contain these files:

Dependencies Installation

Install the packages


npm install --save-dev parcel
npm install --save @ledgerhq/hw-app-eth
npm install --save @ledgerhq/hw-transport-webhid
npm install --save ethers
PackageWhat does it do?
parcel (opens in a new tab)It is a build tool that will help you package your application to run it in the browser.
@ledgerhq/hw-app-eth (opens in a new tab)It will help you ask your Ledger Nano to access the ethereum address.
@ledgerhq/hw-transport-webhid (opens in a new tab)It provides you with all the methods to interact with your Ledger with an HID connexion.
ethers (opens in a new tab)It provides you with all the methods to interact with the ethereum blockchain.

Modify Package.json

Modify the 5th line: "main": "index.js" => "source": "index.html" And ensure you have this line in scripts:

  "scripts": {
    "start": "parcel"

Add this at the end of the script:

  "alias": {
    "@ledgerhq/devices": "@ledgerhq/devices/lib-es"

Your file should now look like this:

    "name": "e2e-eth-tutorial",
    "version": "1.0.0",
    "description": "",
    "source": "index.html",
    "scripts": {
      "start": "parcel"
    "author": "",
    "license": "ISC",
    "devDependencies": {
      "parcel": "^2.3.2"
    "dependencies": {
      "@ledgerhq/hw-app-eth": "^6.26.0",
      "@ledgerhq/hw-transport-webhid": "^6.24.1",
      "ethers": "^5.5.4"
    "alias": {
      "@ledgerhq/devices": "@ledgerhq/devices/lib-es"

Tutorial Test

Start the Development Server

Now that the Setup is finished, the app has to be built to be displayed. Start the development server:

npm run start

Now the application is up and running. Open the browser and go to localhost:1234, it will display :

Application running on browser Fig. 5: Application Running on Browser

Plug Your Ledger Device

Before clicking on the text connect your Ledger to the USB port, unlock it and run the ethereum application. The steps are described below.

Nano Enter Code Pin

Connect Your Ledger to the Application

Now you can click on the "Connect your Wallet" button and a modal will be opened. Click on the Ledger logo.

Choice of Wallet Fig. 9: Choice of Wallet

Now choose the Ledger Nano to connect it to the browser.

Connect the Ledger Nano Fig. 10: Connect the Ledger Nano

If all goes well, the input fields will be filled with data. The greyed input is not to be changed and it is directly extracted either from the blockchain or from your Ledger Embedded application.

Application After Connecting Ledger Nano Fig. 11: Application After Connecting Ledger Nano

Create a transaction to transfer ethereum

Now that the inputs are filled with data. It is time to transfer some ether tokens from your Ledger ethereum account to another account (you can keep the default account on the "index.js" file).
Therefore, click on "Create Transaction" to create the transaction which will be signed by your ledger before sending it to the blockchain.

Application After Connecting Ledger Nano Fig. 12: Application After Connecting Ledger Nano

When the transaction proceed and finalize, an URL will be displayed on the screen. This URL is a link to Ropsten Etherscan to review the transaction.
There you can find all the information concerning the transaction you have previously sent.

Result after Sending Transaction Fig. 13: Result after Sending Transaction

If you go on Etherscan you can see the information of your transaction.

Congratulations, you have successfully built your first transfer application connected with Ledger !!!
