To streamline communication with currencies from different external sources, Payment Gateway core component accepts their varying parameters and settings for communication, and converts them into a unified format.
Unification of variable formats for Payment Gateway, is done by creating Payment Interfaces that are dedicated to the currency source. Currency Sources can be multiple banks, payment processing services or blockchain nodes. Considering that all inbound and outbound transactions are processed by the Payment Gateway Module, the unified format introduced by "Payment Interfaces" enables Marionette’s Accounting Engine to process data from unlimited sources and update accounting records.
