Is Coti part of Cardano?

Could you please elaborate on the relationship between COTI and Cardano? Are they affiliated in any way, such as a partnership or collaboration? I'm curious to understand if COTI is a part of the Cardano ecosystem, perhaps as a token or a service provider. It seems that both projects are focused on blockchain technology and have similar goals, but is there a direct connection between the two? Your insight into this matter would be greatly appreciated.
