Can participants pay in their own currency?

Only one currency can be set for each campaign.

Participants from any location can make payments using credit or debit cards if a Stripe account is connected to the campaign. (A Stripe account must be connected to all Voluntary Contribution and Fixed Fee campaigns. )

Stripe then calculates the exchange rate at the time the payment is made and the funds are received by the campaign manager in the currency as per their Stripe account.
