Getting set up for CorDapp development

Software requirements

Corda uses industry-standard tools:

Please note that OpenJDK builds usually exclude JavaFX, which our GUI tools require.

  • IntelliJ IDEA - supported versions 2017.x, 2018.x and 2019.x (with Kotlin plugin version 1.2.71)
  • Gradle - we use 4.10 and the gradlew script in the project / samples directories will download it for you.

Please note:

  • Applications on Corda (CorDapps) can be written in any language targeting the JVM. However, Corda itself and most of the samples are written in Kotlin. Kotlin is an official Android language, and you can read more about why Kotlin is a strong successor to Java here. If you’re unfamiliar with Kotlin, there is an official getting started guide, and a series of Kotlin Koans
  • IntelliJ IDEA is recommended due to the strength of its Kotlin integration.

Following these software recommendations will minimize the number of errors you encounter, and make it easier for others to provide support. However, if you do use other tools, we’d be interested to hear about any issues that arise.

Set-up instructions

The instructions below will allow you to set up your development environment for running Corda and writing CorDapps. If you have any issues, please reach out on Stack Overflow or via our Slack channels.

The set-up instructions are available for the following platforms:




  • Visit
  • Click the “64-bit Git for Windows Setup” download link.
  • Download and run the executable to install Git (use the default settings)
  • Open a new command prompt and type git --version to test that git is installed correctly






These instructions were tested on Ubuntu Desktop 18.04 LTS.


  • Open a new terminal and add the Oracle PPA to your repositories by typing sudo add-apt-repository ppa:webupd8team/java. Press ENTER when prompted.
  • Update your packages list with the command sudo apt update
  • Install the Oracle JDK 8 by typing sudo apt install oracle-java8-installer. Press Y when prompted and agree to the licence terms.
  • Verify that the JDK was installed correctly by running java -version


  • From the terminal, Git can be installed using apt with the command sudo apt install git
  • Verify that git was installed correctly by typing git --version


Jetbrains offers a pre-built snap package that allows for easy, one-step installation of IntelliJ onto Ubuntu.

  • To download the snap, navigate to
  • Click Install, then View in Desktop Store. Choose Ubuntu Software in the Launch Application window.
  • Ensure the Kotlin plugin in Intellij is updated to version 1.2.71 (new installs will contains this version)


These instructions were tested on Fedora 28.



  • From the terminal, Git can be installed using dnf with the command sudo dnf install git
  • Verify that git was installed correctly by typing git --version


Next steps

First, run the example CorDapp.

Next, read through the Corda Key Concepts to understand how Corda works.

By then, you’ll be ready to start writing your own CorDapps. Learn how to do this in the Hello, World tutorial. You may want to refer to the API documentation, the flow cookbook and the samples along the way.

If you encounter any issues, please ask on Stack Overflow or via our Slack channels.
