The IOTA Extension Interface provides an API that connects IXI modules to the Ict core client. IXI modules are applications built on top of the Tangle protocol.

# clone the example source code
git clone https://github.com/iotaledger/ixi

You can also manually download the repository source code if you don't have Git.

# if you are using intellij (requires Gradle)
gradle idea

This part is where you get creative. Implement your ideas in src/main/java/org.iota.ixi/Ixi.java. Make sure to change the name from example.ixi to whatever your IXI module is called.

This step requires Gradle.

# move into the cloned repository (in which your build.gradle file is)
cd Desktop/ixi

# build the .jar file
gradle fatJar

You should now find your finished ixi-{VERSION}.jar file.

The ict.cfg file will be created the first time you start your Ict. Just make sure that the ict_enabled property is set to true:

ict_enabled=true

java -jar ict-{VERSION}.jar

The name of your Ict is defined in the ict.cfg file.

java -jar ixi-{VERSION}.jar {ICT NAME}
