Testnet prototype - MVP scope clearly marked

Arqis

Simple USDC invoice payments on Arc for individuals and small businesses: create an invoice, let the payer pay with Arc Testnet USDC, track settlement, and help testers get setup.

Testnet MVP: Current checkout supports USDC on Arc Testnet through the payer invoice inbox. Wallet QR is for direct transfers only.

Seller creates invoice

Keep this step simple. The seller only enters invoice details.

Enter a registered Arqis payer name.
Payer wallet resolves automatically from the Arqis name.
Amount must be 1-50,000 USDC.
Memo is required and limited to 99 characters.
In the current prototype, the seller settlement wallet is the registered Arqis wallet. A dedicated Seller Settings screen is planned.
Enter the payer Arqis name, amount, memo/order ID, and expiry to send an invoice.

Created invoices

Invoices you sent from your Arqis name. This list auto-refreshes while your wallet is connected.

No created invoices yet.
Send an invoice to another Arqis user and it will appear here with its status.

Pay Invoice

Only for the payer. Open an invoice from the inbox to show testnet checkout details. Wallet QR in setup is only for direct receives.

No invoice loaded yet.
Create Invoice has not produced a payable checkout yet. Once an invoice exists in your inbox, amount, memo, and recipient will appear here.
