I just sold some XMR over Bitsquare. But the XMR address seems to be invalid. Since I am not a specialist on XMR I am not really sure about it. Here is the output of my local XMR simplewallet:
[wallet -------]: transfer 9yK2DTga14chA3kvNDKcHnQWw9FHnsK5g25v4pvLeC7aKyJQ43GuN5713n2xwurGHxFBwGP9FanmWA88uCWbmzZZ4XcdSZe 0.33
Error: wrong address: 9yK2DTga14chA3kvNDKcHnQWw9FHnsK5g25v4pvLeC7aKyJQ43GuN5713n2xwurGHxFBwGP9FanmWA88uCWbmzZZ4XcdSZe
since Monero is anonymous on its blockchain even checking it on http://moneroblocks.info/ does not help much:
Shame on you!
There is no such thing as 9yK2DTga14chA3kvNDKcHnQWw9FHnsK5g25v4pvLeC7aKyJQ43GuN5713n2xwurGHxFBwGP9FanmWA88uCWbmzZZ4XcdSZe in Monero’s blockchain!
You can open a support ticket by pressing ctrl+o or cmd+o.
Then the arbitrator can check with the peer and close the case. Sec. deposit will get returned in such cases.
