What does cat 1 and cat 2 mean?

Could you please clarify what you mean by "cat 1" and "cat 2" in the context of cryptocurrency and finance? These terms are not universally recognized in our industry, so it's possible they are specific to a particular project, regulation, or classification system. If you could provide more context or explain where you encountered these terms, it would help me give you a more accurate answer. Are they perhaps related to the categorization of cryptocurrencies, risk levels, or some other aspect of the field?
