What does USD Pax mean?

Excuse me, I'm curious about a term I've encountered recently in the world of cryptocurrencies and finance. Could you please explain to me what USD Pax stands for? I've heard it mentioned in a few conversations, but the specifics are still quite unclear to me. Is it a new type of digital currency? Or perhaps a service related to the exchange or storage of traditional fiat currencies? Your expertise in this area would be greatly appreciated in clarifying this matter for me. Thank you for your time and assistance.
