When you receive payment in other currencies other than your default currency, the money will be deposited to your account in your default currency (please note that your default currency is defined by your country of residence)
After the money has been converted to your default currency, the transaction charge of 4.5% will be deducted. For example, if your account is domiciled in Naira and you have international gateway enabled. When a user pays for an item in USD, the money is first converted and deposited to your account in Naira (based on VoguePay’s FX rate). After this, the 4.5% transaction charge will be deducted.
In case you DO NOT want your transaction in USD to be converted to your default currency, you need to open another VoguePay account with USD as your default currency.
