Hello,
I have been able to develop a solution for this.
I believe the best approach is to pay out crypto commissions in the currency that the cart was paid. If this is possible because the cart was not paid with a cryptocurrency, then the plugin converts the value to a default currency that the admin has selected. The commissions will then be paid out in that cryptocurrency.
(At first I thought it would be a good idea to let each vendor choose their preferred cryptocurrency, but this is technically a lot harder, because the Marketplace code does not make this easy to extend. Also, if you let each vendor choose their preferred currency for payments, then you need to maintain significant balances on each of the coins they select. Instead, if vendors get paid in one cryptocurrency then you only need to keep some funds in that currency.)
The patch will be out once I have a solution for the missing withdrawal row in the Banking Overview.
I will post again here when the patch is out.
with regards
