A person is browsing their phone in a European pizza shop and notices the trending discussion online about new directions in this wave of technological applications.

What are the key points? For those who frequently travel across multiple countries in the future, they might truly be able to get rid of the old process of frequent currency exchanges, calculating exchange rates, and bearing cross-border transaction fees.

The emergence of blockchain payment solutions means users can settle globally with a unified account, truly achieving "lightweight accounts and intelligent settlements." This is not only a technological upgrade but also a redefinition of the international financial intermediary model.
