Hello TechSupport! I have made an exchange at Changelly but the first XEM wallet I have given was an error and I have corrected it, but besides the NEM wallet address, they require also the "extra ID (memo).
They said, it is in the message, but I can not see any other alphanumeric key or code besides my wallet address.
Please advise where to find this extra ID or there is really none?
Thanks and Regards,
