Cross-service transactions for peer-to-peer (p2p) payment platforms

Abstract

An example computing platform is configured to receive a request from a first user account of a first P2P payment service that a cross-service transaction be initiated with another user account of another P2P payment service. Based on the request, the computing platform generates a transaction identifier for the transaction and sends the identifier to the first P2P payment service's platform. Thereafter, the computing platform receives, from a second P2P payment service's platform, the transaction identifier and an identifier of a second user account of the second P2P payment service and responsively determines that the cross-service transaction comprises a transfer of funds between a first financial account associated with the first user account and a second financial account associated with the second user account. The computing platform then selects and causes a given payment rail platform to transfer funds between the first and second financial accounts.
