Approaches disclosed herein provide digital payment processing that integrates cryptocurrency transactions with traditional banking systems through the use of, for example, blockchain technology in a streamlined digital payment process. As an example, a digital payment processing system may integrate cryptocurrency with exchanges and banking systems via APIs. Such integration allows for the determination and use of real-time exchange rates, as well as almost immediate transfer of funds between cryptocurrency and fiat (traditional) or other such currency. By automating the exchange process and connecting directly to financial institutions for instant fiat settlement, such approaches can effectively avoid the usual delays of blockchain (or other distributed ledger-based) confirmations. Such a system may also utilize other technologies for facilitating a faster transaction process, such as off-chain solutions or layer-2 scaling solutions.
