ThirdFi offers Fiat-to-Crypto (On-ramp) payment services with REST API. ThirdFi allows developer apps to enable users to buy crypto directly inside their apps using fiat currencies via different payment methods such as cards, bank transfers, and other local payment methods.

ThirdFi integrated with Transak to provide enhanced on-ramp services with Transak Widget UI, which can be integrated into the developer server backend via REST API. Transak also helps us to verify the user KYC during the on-ramp payment services.

In the future, there will be more payment solution providers to be integrated in ThirdFi API.
