Hello,
Apologies for the long delay, it turned out that there were a number of issues with the gateway. Hopefully I have addressed all of them now, but please let me know if you spot any other issues.
Please see the release notes for version 2.2.0 of the payment gateway: https://www.dashed-slug.net/wcmp-bug-fixes-version-2-2-0/
I have found it is simpler for admins to pay commissions in the same currency as that the user has paid in. This eliminates any need for conversion, which can be done manually by the vendors.
Withdrawals are now fixed and are described in the FAQ section.
with regards
