Abstract: An interface associated with a fiat currency account of a customer is enhanced to accept payment on the account via a digital wallet of the customer. A gateway service is processed when the option is selected which causes payment in a customer's wallet to be transferred over a blockchain to a gateway service's wallet. The gateway service then transfers an equivalent amount from a financial account of the gateway service to a financial institution's account. The gateway service also provides an account identifier for the account of the customer to the financial institution. The financial institution credits the amount as payment received from the customer and updates the interface to include the payment and the credited amount on the account.
