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 any chain. CCTP V2 sweeps USDC home to Arc with sub-second finality. Quote freeze locks the rate for 15 minutes.

Receipts

Stenn-Proof receipts.

Every payment mints a public on-chain receipt. Both parties sign. Anyone can verify against Arc without trusting Klaro, the vendor, or the buyer.
