[Autonomous Agents on Obyte](https://developer.obyte.org/autonomous-agents/getting-started-guide) are open compute and open data self-running services.

So I imagine situations in which everyone will eventually run into when they use these services.

One of the first thing is how does one know if they are using the latest version of the service?  

The solution is a autonomous service which allows users to check if the address is the latest version, and allow address transfer to the latest version.

I call it Latest Address Check and Route AA or OAAAA

I only came up with the idea today and there are still some functionality which I am not sure OScript has or not.

Anyways, I am going to submit the idea and work on it some more if others think it's a good idea too.

I imagine everyone will run this as their entry point to their AA service.
