What does STP sell?

Could you elaborate on the nature of the products and services offered by STP? I'm particularly interested in understanding the core offerings that STP specializes in within the cryptocurrency and finance industry. Are they primarily focused on trading platforms, custodial services, investment advisory, or a combination of these? Additionally, I'd like to know if STP caters to retail investors, institutional clients, or both. Finally, is STP known for any innovative products or technologies that set them apart from their competitors in this rapidly evolving market?
