Abstract: Various embodiments are directed to processing conversions of digital assets to other digital assets. An example method includes determining a source exchange rate for a source digital asset and a fiat currency, determining a target exchange rate for a target digital asset and a fiat currency, and generating an aggregated conversion rate for the source digital asset and the target digital asset using the source exchange rate and the target exchange rate. The method further includes executing a digital asset conversion, which includes causing source digital asset units to be debited from a source digital asset user account and causing target digital asset units to be credited to a target digital asset user account, and subsequently executing fiat currency transactions (e.g., settlements) with a first digital asset exchange system associated with the source digital asset and a second digital asset exchange system associated with the target digital asset.
