What ProxyPay is
A merchant payment control plane for accepting USDC on Solana in physical stores. The register issues a signed payment request; the customer's own wallet verifies it and pays the store's own treasury wallet directly. ProxyPay software does not hold, receive or transmit funds, and has no customer signer and no merchant signer.
What a pilot involves
Application
The store applies at /pilot.html, describing its locations, its vault and key arrangements, and its exchange or off-ramp account.
Scoping and quote
The pilot is scoped and priced individually. There is no published price list.
Rehearsal
Key possession checks, seat replacement drills and exception walkthroughs run with the store’s own named people before any real payment.
Integration
The store’s POS is wired to the open request protocol, or staff run the register app beside it during the pilot.
Live pilot
The store accepts stablecoin payments at the register, with reconciliation, refund and close-out proposals running for its locations.
What the store must provide: a multi-approval vault it controls with hardware keys held by named people; at least three distinct people able to approve, plus a plan for replacing a lost key; its own exchange or off-ramp account in good standing under that provider’s rules; a lawful business holding every authorisation its activity requires; a POS to integrate with, or staff to run the register app; and a named person who owns reconciliation at the end of each day.
What the store controls
- The treasury: funds sit in a multi-approval vault the store controls, not a ProxyPay account.
- Approval roles: named people hold approval seats; ProxyPay holds no seat, no share and no recovery key.
- Refunds policy: a manager proposes a refund against a specific original payment, and merchant-controlled keys approve it. The store sets and states its own refund policy.
What is final and irreversible
- A confirmed stablecoin payment cannot be reversed. A refund is a separate, new transfer that a manager proposes and merchant-controlled keys approve.
- Key loss is the store’s loss: nobody, including ProxyPay, can restore access to the store’s vault.
- Amounts, addresses and timestamps settle on a public ledger, permanently visible to anyone, including authorities.
What it costs
Quoted per pilot. ProxyPay software cost is paid by the merchant to ProxyPay, LLC. The customer pays the network fee on their own payment; the merchant pays the network fee on any refund or sweep, its own vault and hardware key costs, its exchange and withdrawal fees, and its bank’s deposit fees — none of those are paid to ProxyPay.
What ProxyPay does not do
- It does not hold, receive or transmit funds, and has no signing key of any kind.
- It cannot approve, sign or submit a payment, a refund or a sweep — every money-moving action is a proposal a merchant-controlled key authorises.
- It cannot freeze, seize, redirect or reverse anyone’s money.
- It does not perform the merchant’s identity or business verification (KYC/KYB) — that is the merchant’s exchange or off-ramp provider’s role.
