Surfaces

Everything a vendor needs to get paid and prove it.

Each surface ships behind the same wallet and shares one balance. Stages are honest per principle 8 — no marketing-grade claims hidden in the small print.

Invoicing

Hosted USDC invoices.

Issue an invoice. Customer pays from a hosted page. Live Arc settlement is used when contracts are configured; otherwise the flow is clearly simulated.

Receipts

Klaro Proof receipts.

Receipt pages are shareable and verifiable by hash. On-chain minting happens only in live-contract mode; simulator receipts are labelled as previews.
