Abstract: Disclosed are various embodiments for determining availability of payment entities existing on various payment networks. In one non-limiting example, a computing device is configured to transmit a query to a first network hub for a status of a participant system. The participant system is connected to the first network hub. The computing device is configured to determine a participant status for the participant system based at least in part on a query response from the first network hub. A participant status cache is updated based at least in part on the participant status. The participant status is propagated to a second network hub connected to the first supernetwork instance. The participant status is propagated to a second supernetwork instance connected to the first supernetwork instance.

Abstract: Disclosed are various embodiments for facilitating payments between members of separate payment networks. A first instance of a supernetwork can receive a payment request from a source network hub connected to the first supernetwork instance and linked to a first payment network, the first payment request specifying an identifier for a recipient institution and an amount of the payment request. The first instance of the supernetwork can then query a participant status cache to identify a destination network hub linked to a second payment network associated with the recipient institution. Next, the first instance of the supernetwork can query a participant registry to identify a second supernetwork instance connected to the destination network hub. Finally, the first instance of the supernetwork can forward the payment request to a second global transaction router hosted by a second supernetwork instance connected to the destination network hub.
