Passive management of multiple digital tokens for an electronic transaction

A method, comprising:

• receiving, by a first service provider, a first request for payment for a transaction conducted via a mobile computing device associated with a user having an account with the first service provider, the first request received from a first mobile application on the mobile computing device;
• determining a first funding instrument linked to the account;
• sending a first tokenized communication including a first amount for the transaction through a computer network to a first entity associated with the first funding instrument;
• receiving a notification from the first entity that the first request has been declined;
• in response to the receiving the notification from the first entity that the first request has been declined, fetching metadata from a smart contract recorded in a blockchain and associated with a second mobile application on the mobile computing device, wherein the smart contract comprises a computer protocol that defines a logic for digitally facilitating a passive retrieval of a second funding instrument for use in the transaction;
• based on the metadata, identifying a token identifier corresponding to the second funding instrument, wherein the second funding instrument is linked to the second mobile application but not linked to the first mobile application;
• retrieving information corresponding to the second funding instrument linked to the second mobile application based on the token identifier;
• in response to the receiving the notification from the first entity that the first request has been declined and the retrieving the second funding instrument, sending a second tokenized communication including a second request for payment of the transaction using the second funding instrument and a second amount through a computer network to a second entity associated with the second funding instrument;
• receiving a notification from the second entity that the second request has been approved;
• and
• notifying the user through the mobile computing device that the transaction has been approved.

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

• receiving, by a first service provider, a request for payment for a transaction conducted via a first mobile application installed on a mobile computing device associated with a user having an account with the first service provider;
• sending a first tokenized communication including a first amount for the transaction through a computer network to a first entity associated with a first funding instrument linked to the first mobile application;
• receiving, from the first entity, a payment declined message associated with the first amount;
• in response to the receiving the payment declined message, fetching metadata from a smart contract recorded in a blockchain and associated with a second mobile application installed on the mobile computing device, wherein the smart contract comprises a computer protocol that defines a logic for digitally facilitating a passive retrieval of a second funding instrument for use in the transaction;
• based on the metadata, identifying a token identifier corresponding to second funding instrument, wherein the second funding instrument is linked to the second mobile application but not linked to the first mobile application;
• retrieving information corresponding to the second funding instrument linked to the second mobile application based on the token identifier;
• in response to the receiving the payment declined message and the retrieving the information corresponding to the second funding instrument, sending a second tokenized communication including a second amount for the transaction through a computer network to a second entity associated with the second funding instrument;
• receiving from the second entity that the second amount has been approved;
• and
• notifying the user through the first mobile application of the mobile computing device that the transaction has been approved.
