How do I buy a ZK swap?

Hello, could you possibly explain the process of purchasing a ZK swap in a step-by-step manner? I'm fairly new to the cryptocurrency market and have heard a lot about the potential of ZK swaps but am unsure of how to proceed. Would I need to set up a cryptocurrency wallet first? What platforms offer ZK swaps, and are there any specific requirements or fees involved? Additionally, are there any risks or considerations I should be aware of before making such a purchase? Your guidance would be greatly appreciated.
