What is BitDelta?

Could you please explain to me what BitDelta is in a concise manner? I'm not too familiar with the intricacies of the cryptocurrency world, so I'm hoping for a clear and simple definition. Is it a platform, a token, or something else entirely? How does it differ from other similar entities in the industry? Additionally, what are some of its main features or advantages that make it stand out? I'm eager to learn more about this and how it fits into the broader landscape of cryptocurrency and finance.
