如何使用 United States Dollar (USD) 购买 Polyhedra Network (ZKJ)

To buy Polyhedra Network using United States Dollar, first, find a cryptocurrency exchange that supports the ZKJ/USD trading pair，例如 Crypto.com. Create an account, verify your identity, and deposit your USD into your exchange wallet. Locate the ZKJ/USD pair on the trading platform and place an order to exchange your United States Dollar for Polyhedra Network.
