Particular embodiments determine, at least in part by a computing device of a payment service, to associate a data object with a user account that is associated with a stored balance managed by the payment service. The computing device associates an amount of the data object with a distinct stored balance associated with the user account. The distinct stored balance is associated with a condition of use. The computing device monitors transaction data associated with users of the payment service. The computing device identifies, from the transaction data, a transaction associated with an identifier associated with the user account. Based on a determination that the transaction satisfies the condition of use, processing payment for the transaction using at least a portion of the distinct stored balance prior to using the stored balance.
