RADR lab has perfected its payment interface for improving the RADR ecosystem. The new interface document is released in the developer center at: https://radarlab.org/dev/radar_pay.html . The eligible third-party malls now could do payment with VBC via the payment interface.
The interface adopts a Web call mode, likes of OAuth2. The interface is simplified to have 2 primary interfaces only. The payer must be the existent user of RADR holding VBC. In the online malls which have got access to the payment interface, users are allowed to pay with VBC. The payment will be settled instantly without any extra fee except for a 0.1% fee required by the underlying network.
Keeping perfecting the existent functions and introducing new functions, RADR is working on a more abundant and robust ecosystem.
