What does Pyusd stand for?

Excuse me, I'm curious about a term I've encountered in the cryptocurrency and finance world. Could you please elaborate on what "Pyusd" stands for? I've seen it referenced in a few discussions but haven't been able to find a clear definition. Is it a specific type of cryptocurrency, a financial instrument, or perhaps a service related to the industry? Any clarification you could provide would be greatly appreciated. Thank you for your time and assistance in clarifying this matter.
