Where can I buy a Pax Dollar?

Excuse me, could you please elaborate on where exactly one can purchase a Pax Dollar? I've been interested in diversifying my portfolio and Pax Dollar seems like a promising option, but I'm unsure of the specific platforms or exchanges that offer it. Could you guide me in the right direction? Additionally, are there any precautions I should take into account while making such a transaction? Thank you for your assistance.
