Small bugs have also been fixed quickly with v13.0.1.


For the CLI lovers out there we recently rolled out v5.0.0 which introduces a lot of bug fixes and new features.

Contracts Editor

In case you quickly wanna start developing / prototyping a Sophia Smart Contract in the browser, you should check out the latest version of the Contracts Editor, which now also also generates and displays you the according ACI of the contract that you can use in your application to interact with a deployed Smart Contract.


  • The alternative online editor AEstudio is currently outdated, so we recommend you to use the Contracts Editor.
  • It is also possible to use GitPod to have a full VSCode IDE running in the browser that includes Sophia Syntax Highlighting and has aeproject pre-installed. Reach out to Marco if you wanna learn more about this!
