What confuses me is entering the Refund address, which is not mandatory, but can be added later. However, during the process, I did not have the opportunity to enter it afterwards. Did I overlook it and why is it not mandatory? If a refund of the address was required, would I have to request a refund from support and what does that process look like?
If you did not include a refund address during the transaction process and there is a need for eXch to refund you, it would be sent to the address that you used to deposit the funds. In other words, if you fail to include a refund address, your deposit address becomes your refund address.
