Hello, Zcash community!
I have just submitted a ZCG application for ZEC Invoice Preflight: ZIP-321 Validation for Zcash Merchacnts
Live demo: https://zcash-invoice-preflight.vercel.app/
The tool catches invalid Zcash payment requests (memo on transparent address, network mismatch, bad amounts) before a merchant shares a QR. It is a BTCPay companion (handoff JSON + importable library),
Feedback and questions welcome here.
I will keep this thread updated through review and, if funded, milestone reports.
