Tell me about a user need that is not being met by the market. How would you validate a solution for it?

A significant unmet user need exists in the realm of cross-border e-commerce: the absence of instant, seamless refunds. International refunds are often plagued by delays, typically taking days or weeks to process due to currency conversions, interbank transfers, and regulatory hurdles. This friction point causes considerable frustration for consumers accustomed to the immediate refund experience of domestic transactions.

To validate a solution, I would begin with user interviews and surveys to quantify the pain points and understand the desired speed and process. Subsequently, I'd develop a Minimum Viable Product (MVP) focusing on a specific corridor or payment method, perhaps leveraging blockchain or specialized payment gateways. Success would be measured by metrics like refund processing time, user satisfaction scores, and adoption rates, comparing them against existing benchmarks.
