Is SingularityNET on Cardano?

Could you please clarify for me if SingularityNET is indeed operating on the Cardano blockchain? I've heard rumors about this but I'm eager to get a definitive answer. I'm quite interested in both projects and their potential synergies, so I'd appreciate it if you could shed some light on this matter. Is there any official announcement or documentation that confirms or denies this integration? Additionally, could you elaborate on the potential benefits or challenges that such a partnership might bring to both platforms? Thank you in advance for your assistance.
