The thesis

Two types of crypto payment.
Only one of them is actually crypto.

What everyone builds today
Consumer crypto→Convert to fiat→Visa / MC rail→Merchant

Still pays Visa fees. Still needs KYC. Adds friction on top of broken rails.

What crypto payment should be β€” and what we ship
Consumer crypto→Crypto rail→Merchant

Instant on-chain settlement. Near-zero fees. No chargebacks. No middlemen. Fiat lands in the merchant's bank.

How it works

Tap. Settle. Off-ramp.

ERC-681 standard. NFC or QR. No app install, no KYC, no card.

02 Β· PROTOCOL

SessionReceiver collects, ClearingVault distributes β€” fees, hooks, payout β€” atomically.

03 Β· MERCHANT

AUD lands in your bank.

AUDD or AUDM redeems through AFSL-regulated issuers. Same/next business day.

Positioning

The missing settlement layer.

x402 and MPP tell agents how to pay. We handle what happens after they do β€” clearing, fees, hooks, payout, off-ramp. On the same rail as physical retail.

x402 / MPP
β€œPay me” β€” request layer
  • No merchant clearing or settlement
  • No fiat off-ramp
  • No terminal integration for physical POS
  • No fee accounting, hooks, or composability
OpenPasskey
β€œHere’s how” β€” settlement layer
  • SessionReceiver β€” deterministic payment address
  • ClearingVault β€” clearing, fees, hooks, payout
  • Terminal-native β€” physical POS, no server
  • Off-ramp β€” stablecoin β†’ AUD via AUDD / AUDM
Proved at the Tempo hackathon: an MPP request triggered the payment, our ClearingVault settled it. Same rail, human or agent.
β€œWe were paying Square 1.6% on every coffee. With OpenPasskey it's 0.6% and the money is in our account before lunch, not Tuesday.”
