Ardor is a blockchain-as-a-service multi-chain platform that evolved from the time-tested and energy efficient Nxt blockchain. The Ardor mainnet launched on 01 January 2018. Through this documentation, you will learn all about the extensive capabilities of the Ardor platform. Begin developing your knowledge by reading about each of Ardor’s distinctive Features or consider trying the technology yourself by following some Basic Tutorials. For developers, documentation is provided for each of Ardor’s more than 250 APIs that can be used to quickly and cost-effectively deploy dApps and smart contracts that integrate your business processes with the Ardor blockchain. Check this site regularly for new content and updates as additional features are released.
Before we begin, if you haven’t already done so, you may wish to check that you have the correct (usually most recent) version of Java installed on your computer. You can use any compatible Java available for your platform. The minimum required version is Java 8. The recommended version is Java 11. We usually test with OpenJDK 11.
To start with Ardor/Ignis, you must first download the client, also known as a "wallet", on your machine. The client is distributed as a binary package for the following platforms:
- Download the Windows installer for the latest official Ardor Client 2.2.6 from https://www.jelurida.com/ardor-client.exe or the latest experimental version 2.3.1e from https://www.jelurida.com/ardor-client-experimental.exe if you want to test the newer features such as the new login page.
- Ardor's Windows client comes as an .exe file. After downloading it, you can verify its integrity by performing an integrity check
- Run the installer and follow the instructions on screen. Note that you can select either the testnet or mainnet during installation, if further details are needed please follow the step-by-step guide. Once installed icons will be created by default in your desktop and Start Menu.
- You can now run the Ardor software by clicking on the Ardor icon. After a few seconds, the Ardor wallet will open in its own window.

Here is the guide to installing the Ardor Client on a Linux 64-bit platform. 32-bit installation instructions are very similar; you just might need to download the 32-bit version of Java instead of the 64-bit one.
You can use this instructions on your Linux VPS as well.
Set up Java
You can skip this step if you already have Java installed. Otherwise, you can install it via your distribution repository doing the following (for Ubuntu/Debian builds):
sudo apt update sudo apt install openjdk-11-jre-headless
You can also use `openjdk-8-jre-headless` or any other Java 8+ compatible version.
Install and run the Ardor Client
Using the Unix installer
You can execute the unix installer executable compatible with most linux distributions from ardor-client.sh and follow the instructions. You can also download the experimental version ardor-client-experimental.sh if you want to test the newer features such as the new login page.
wget https://www.jelurida.com/ardor-client.sh sh ardor-client.sh
Using the Universal Zip Package
You can follow the more generic instructions as explained below:
- Change to your home folder and download the latest client (version 2.2.6 or the experimental 2.3.1e):
wget https://www.jelurida.com/ardor-client.zip.ascand verify that the signature is correct:
gpg --with-fingerprint ardor-client.zip.asc
- Unzip it:
Using the experimental version is as follows:
wget https://www.jelurida.com/ardor-client-experimental.zip.asc and verify that the signature is correct:
gpg --with-fingerprint ardor-client-experimental.zip.asc
Run the Ardor client
- Now it's time to start the software. You may start it by executing
./run.sh --daemonfor running the Ardor node in the background, which you will find in the ardor directory. The server will be active as soon as you see in the window a text similar to this:
Ardor server 2.2.6 started successfully.This shell window will be running the Ardor server and print all the Ardor log messages, so it needs to stay running!
- Open http://localhost:27876/ from a web browser to access the Ardor Client. Please note that, if it's the first time you run Ardor in your machine, the Ardor blockchain will need to be downloaded until it is up to date. Depending on the your network connection speed, this may take a few hours. The Ardor Client will show you a progress bar as the blockchain downloads. Now you can visit the click here for instructions to Create a New Ardor Account.
- NOTE: If you've installed the client on a dedicated server or VPS, you should change "localhost" to your Server/VPS IP.
For installing the Ardor client on a Raspberry pi, you can refer to the description of an implementation with the Ardor client powered by solar panels

Lightweight Contracts documentation
Lightweight Contracts represent a framework for developing a layer of automation on top of the existing Ardor APIs, refer to the official documentation to read more about this feature:
Login to Ardor
There are different ways to login to Ardor to create an account. It is explained in the Login Page Tutorial
Getting your first ARDR
With the Ardor client installed, it is now time to start transacting. To do that, we need to get some tokens, be it ARDR, IGNIS, or any other childchain. The Ardor mainnet is live and actual tokens are in circulation across numerous major exchanges.
Note the tokens we will be using in the next examples are from testnet. These tokens are not traded in exchanges and have no monetary value -- they exist only as a convenience for developers and those willing to experiment with the features.
The process of staking in Ardor is called Forging. Once you have more than 1.000 ARDR you can start forging, thus earning the transaction fees when a block is generated by your node.
Furthermore, you can also opted in to the Node Reward Program by just setting up a node with both the API and peer ports open to the Internet and a public and static IP address.
