Uphold integrated Interledger Protocol (ILP) so we can process payments across different payment networks. This allows us to connect ledgers from two different banks, thereby removing intermediaries and central authorities from the system.
As ILP is currency-agnostic, web monetized sites or anyone using ILP can receive payments in any currency that's supported by their digital wallet and Interledger. It promises to reduce costs and the time required to process cross-border transactions.
