Once your user’s have a sufficient balance of cryptocurrencies in their wallet, purchasing collectibles is super easy! But, on-ramping user funds into cryptocurrencies hasn’t always been easy, until now!The Sequence SDK integrates a variety of payment service providers, like Transak and Sardine, to facilitate on-ramping user funds via a user friendly web-based flow using their credit/debit card.While you can work with either integration directly, it is recommended to work with them via SequencePay so that the appropriate (based on geographic availability and other factors) provider implementation is used.
