Field notes
The homepage describes a pilot-stage payment layer for physical stores using USDC on Solana. Its design separates customer payment from later operational actions: ProxyPay observes public-ledger settlement, records when it saw events, and prepares proposals for refunds, close-outs, and treasury movement. Merchant-controlled keys approve those actions, while ProxyPay claims to hold neither customer nor merchant signing authority. The register presentation uses explicit transaction states and does not rely on colour alone.
