nanopay is a mobile-first financial app multichain, designed to bring practical crypto utility to everyday users — particularly in emerging markets where access to traditional banking is limited. The app combines peer-to-peer USDC payments, Aave V3 yield-bearing savings, GoodDollar UBI claims, and a location-based social layer (Geo Chat) into a single progressive web app. Users create self-custodial wallets, earn XP through daily financial activity, and redeem that XP for USDC — making basic financial engagement genuinely rewarding. nanopay's Sybil resistance layer (MaxFlow) uses a trust graph built from social vouching to verify real humans without centralized identity gatekeeping. This makes the platform usable by people who lack government-issued ID, a key barrier in many markets. The platform currently serves 41,000+ wallets with organic, zero-paid-marketing growth — primarily across East Africa. It operates as a PWA, meaning no app store is required, lowering the access barrier further. nanopay's broader goal is to serve as last-mile financial infrastructure: a layer where UBI, savings, payments, and community connect in one place, accessible to anyone with a smartphone and an internet connection.
