Abstract: Systems and methods are disclosed for managing a plurality of supplemental payment sources of a user. One method includes: receiving a primary payment source account of a user for a purchase transaction originating at the merchant, the primary payment source account having an identifier associated with one or more supplemental payment source accounts; receiving supplemental payment source accounts of a user for applying to a payment transaction originating at the merchant; receiving, from a user device, preference settings to apply one or more of the supplemental payment source accounts to a payment transaction; receiving a transaction authorization request from the merchant or merchant acquirer for a transaction amount; and determining a combination of payment source accounts to use in the payment transaction, from a group comprising one or more supplemental payment source accounts and the primary payment source account, and any of one or more preference settings.

Abstract: User devices are disclosed for managing a plurality of supplemental payment sources of a user. One method includes: generating and displaying a user interface prompting a user to input: an identifier of a primary payment source account for applying resources to transactions originating at one or more merchants, the primary payment source account being accounted for in a first data structure of a shared ledger and having its identifier linked with one or more supplemental payment source accounts; identifiers of one or more supplemental payment source accounts for applying resources to transactions originating at one or more merchants, the supplemental payment source accounts being accounted for in second and subsequent data structures of the shared ledger; and preference settings for applying resources of the primary payment source account and the supplemental payment source accounts to transactions, based on identities or categories of merchants involved in the transactions.
