What partners and investors ask first: protocol fees, where funds flow, and how we relate to x402 / on-chain stacks. This is a public note, not normative spec — see the Constitution.
Usually not. Trial and the zero node default to mock or sandbox. Production settlement uses licensed or declared partners; the protocol requires SETTLED to bind vdc_id + an honest settlement_receipt.
| Revenue | Is | Is not |
|---|---|---|
| Hosted reference node | Ops, quota, audit | Protocol license fee |
| Compatibility certification | Steward review (may be free early) | Paywall to join |
| Settlement routing / reconcile | VDC → invoice / reconcile rows | FX spread |
| Enterprise support | Red Hat model | Private protocol |
Interoperate, not replace. x402 may be one settlement leg; we differentiate on verifiable delivery + cross-agent reputation + settlement-agnostic ontology — not another charge API.
No. Claim is transfer of settlement rights anchored to a signed VDC, not a circulating token.
Honesty. Claiming production settlement while only running mock leads to downgrade or removal in the compatibility matrix.
