@adshmh Let me know when you have cycles to pick this one up. I'll provide some more details, and can help with the design of the user-interface, but it'll involve a few things like:

1. Using ignite to scaffold new types + transactions -> committing those
2. Implementing the business logic, CLI component, etc...
3. Documentation for the CLI + docs
4. Unit + Integration + E2E tests
5. Ensuring parity with more

Let's pair when you get around to it.
