The American Xsolla mobile payment gateway is one of the very few payment service providers that deal solely with the online video games sector and is therefore not a payment service provider as such. To those that create games, however, we thought we should add it, especially as they enable credit/debit cards, gift cards, PayPal, Boleto, Skrill, Amazon Pay and hundreds of other types of payment options. They basically assist you through the entire process of video game creation and marketing, even dealing with accounting and VAT and covering fraudulent purchases. For this service, the features of which are listed on their site, you pay a fee which isn’t mentioned. Best to contact them to make sure.
