Which currencies can a program pay in?

Euros, US dollars or pounds sterling. The brand chooses when it makes the program, and it is fixed once a creator has applied. Every commission, prize and payout on that program is in its currency.

Amounts in different currencies are never added together: dashboards show each separately, and a creator owed in two is paid twice, once in each. An order reported in another currency is recorded but not paid, with the reason.
