Abstract: Systems, methods, and computer-readable storage media for locking-in currency exchanges. One method includes providing, by a graphical user interface (GUI) of a wallet application, a customer request, wherein the customer request is a request for a currency transfer between a customer account of the customer to a recipient account of a recipient, wherein the customer account is associated with a first type of currency and the recipient account is associated with a second type of currency, presenting, by the GUI of the wallet application, a locked-in exchange rate for a time limit and data corresponding to the exchange rate and the time limit, exchanging, by the wallet application, an amount of the first type of currency for an amount of the second type of currency based on the exchange rate, and receiving, by the GUI of the wallet application, an indication of a transferred amount for a currency transfer.
