Receipt Protocol

Operating spec for posting the existing Passport schema to EAS on Base after a live Coinbase Business settlement. Schemas, what a UID attests, refund supersession. Instant markdown. Not a token, not a deed, not a tax opinion.

$47.00

Settles as 47.00 USDC on Base. Coinbase Business takes its payment fee. SSDF INC receives the net.

  • Irreversible once paid. No card chargebacks. Refunds go through the Coinbase Business refund endpoint.

Electronically delivered. Not Florida sales-taxable (Rule 12A-1.032, F.A.C.). Delegated use books a 12% SSDF royalty on first pulse.
