Klaqo: a payment prototype built for Plata
Luka Ivanyshyn presents a working A2A/QR payment-system prototype, with separate merchant POS and customer-wallet demos, as a proposal for Plata’s B2B expansion.
- For
- Payment engineers and fintech product teams
- Worth noticing
- The page lists unresolved inputs—including actual rail fees, regulatory constraints, baseline conversion, and merchant economics—instead of presenting projected gains as proven.
Field notes
The page breaks the transaction into five states, from QR display through settlement, and describes a serializable PostgreSQL transaction for creating the payment intent and signing its QR. It also presents a duplicate-request case: sending the same POS request twice should produce one payment intent. The commercial case remains unvalidated; the page specifically leaves rail fees, regulatory constraints, and current conversion baselines open.
