One can imagine Venmo, a USD payment processor, integrating with OmiseGO. Users on Venmo will then be able to make intra-network payments (to other Venmo uses) or inter-network payments with other payment processors using OmiseGO. The beauty of OmiseGO's DEX is that these inter-network payments can be across different fiat currencies, cryptocurrencies, and other tokenized assets. This is revolutionary - it breaks down monetary borders and introduces unprecedented liquidity. For example, assuming both Venmo and China’s Alipay are on OmiseGO, a user with Venmo (which uses USD) could visit China and pay a user with Alipay (which uses RMB) through Venmo.
