Abstract: In one embodiment, a method includes storing, in a data store maintained by a payment service, transaction history information associated with two financial accounts of a user. Upon detecting an intent by the user to transfer funds between the first financial account and the second financial account via an application executing on a device of the user, a prediction of a suggested amount of funds for a user to transfer from the first financial account to the second financial account is generated. The payment service sends instructions to the user's mobile device to display the suggested amount of funds with a request to confirm the transfer. Upon receiving confirmation from the mobile device, the payment service initiates the transfer.

Abstract: In one embodiment, a method includes obtaining, by a payment service system, an amount of security assets via a securities exchange system.

The method includes receiving, via an application of the payment service system executing on a device of a user of the payment service system, a request from the user to sell an amount of a security asset owned by the user. The method includes facilitating execution of a sale of the amount of security assets.

Abstract: Payment technology companies are advancing technological solutions to facilitate payments between users and merchants. The complex architecture and software associated with payment technologies can be further improved by offering additional services to users. Some users may find it difficult or overly complicated to use payment technologies. As such, technological improvement are needed to make using payments technology easier, including adding the ability to make payments when funds are not available in an account, or to offer an advance funds transfer if the user would prefer not to use funds stored in a balance.
