VeloPay is a conversational fintech iOS app concept that brings peer-to-peer USDC payments directly inside the chat, so users never have to leave the conversation to send, request, or verify money. In this case study I designed the full flow: smart intent detection that suggests a prefilled payment chip, a quick actions drawer, a transparent send sheet, inline confirmed receipts, and Face ID + PIN security states, all backed by a consistent dark design system. Role: Lead UI/UX Designer Platform: iOS (iPhone 16 Pro) Deliverables: 9 screens, complete flow & design system.
