The Dfns APIs seamlessly interoperate with most fiat on/offboarding providers.
For customers who are not explicitly targeting the US market, we recommend using Mt Pelerin. You can find the full documentation for their solution here. They have highly competitive pricing and limited KYC requirements leading to a seamless user experience.
Mt Pelerin offers flexibility in how their widget is integrated on the web and on mobile. In all cases, developers can pass a blockchain address as the default recipient account for onboarding from fiat to crypto. See the addr parameter description under their options page. Dfns customers can populate this parameter using either addresses for asset accounts or addresses derived from public keys.
In order to offboard from crypto to fiat, Mt Pelerin provides end users with an address to transfer funds to that facilitates the conversion process. Customers can easily initiate payments to these addresses using the Dfns payment APIs.

Joint Dfns/Sardine customers can integrate the platforms by simply passing the destination Dfns wallet address obtained from either addresses for asset accounts or addresses derived from public keys into the Sardine address query string parameter. Here is an example video showing a POC integration.
