01 · Problem
What was stuck
Competing on price only works if the interface makes fees undeniable and the agent experience stays reliable. Over-building “super app” surfaces would dilute the core promise.

02 · What we did
How we shipped
Fee-first messaging, send/receive clarity, and agent findability. Resisted feature sprawl in the narrative — Wave is the cheap, trustworthy transfer layer others complement.
03 · Takeaway
Why it mattered
When fees are the product, the UI’s job is to never hide the number.
Wave’s brand is fee transparency in markets where transfer costs historically punished the poor. Agent networks and simple app flows carry more weight than feature lists.
