Getting started developing CorDapps

Getting started with Corda will walk you through the process of setting up a development environment, deploying an example CorDapp, and building your own CorDapp based on the example.

Setting up a development environment


  • Java 8 JDK - We require at least version 8u171, but do not currently support Java 9 or higher.
  • IntelliJ IDEA - IntelliJ is an IDE that offers strong support for Kotlin and Java development. We support versions 2017.x, 2018.x and 2019.x (with Kotlin plugin version 1.2.71).
  • Git - We use Git to host our sample CorDapp and provide version control.

Step One: Downloading a sample project

  • Open a command prompt or terminal.
  • Clone the CorDapp example repo by running: git clone
  • Move into the cordapp-example folder by running: cd samples/cordapp-example
  • Checkout the corresponding branch by running: git checkout release-V4 in the current directory.

Step Two: Creating an IntelliJ project

  • Open IntelliJ. From the splash screen, click Open, navigate to and select the cordapp-example folder, and click Ok. This creates an IntelliJ project to work from.
  • Click File > Project Structure. To set the project SDK click New… > JDK, and navigating to the installation directory of your JDK. Click Apply.
  • Select Modules > + > Import Module. Select the cordapp-example folder and click Open. Select Import module from external model > Gradle > Next > tick the Use auto-import checkbox > Finish > Ok. Gradle will now download all the project dependencies and perform some indexing.

Your CorDapp development environment is now complete.

Next steps

Now that you’ve successfully set up your CorDapp development environment, we’ll cover deploying an example CorDapp locally, before writing a CorDapp from scratch.
