Where is NXRA listed?

Could you elaborate on the listing status of NXRA? As a keen observer of the cryptocurrency market, I'm particularly interested in understanding the exchange or platform where NXRA is currently being traded. Is it listed on a major cryptocurrency exchange? If so, which one? Or is it available for trading on multiple platforms? Additionally, are there any specific requirements or procedures that investors need to follow in order to purchase NXRA? Your insights would be greatly appreciated as I'm considering adding NXRA to my portfolio.
