USDC payment tool for small merchants in Guatemala — Solana-based, mobile-first, zero dependencies.
Merchant enters an amount in Quetzales, the app converts to USDC at the current rate, generates a Solana Pay QR code, and the customer scans it with any Solana wallet. Payment confirms in under a second, costs fraction of a cent in fees.
No crypto knowledge needed on the merchant side. No hardware. Just a phone and a browser.
I live in Guatemala. Small vendors in tourist spots like Antigua and Atitlán get crushed by card processing fees (3-5%), and a huge chunk of the country's economy runs on remittances that lose 6-8% to intermediaries. Stablecoins on a fast chain fix both problems — if someone builds the interface layer that doesn't require merchants to understand crypto. That's what this is.
- Merchant-facing interface with GTQ amount input
