Flow
Buy USDW: Alice sends Webcash to Exchange. Exchange mints USDW on Notary, returns secret to Alice.
Pay with USDW: Alice holds 10 USDW. She calls Notary replace: 10 in → 3 to Bob + 7 change. Bob imports. Alice keeps change.
Sell USDW: Bob sends USDW secret to Exchange. Exchange burns it on Notary, releases Webcash from pool to Bob.
Demo Restrictions
No real USD backing. Sandbox webcash only. All responses include mode: DEMO_SANDBOX and a warning. Demo USDW cannot fund ServiceEscrow or ProductCertificate. Real-dollar backing requires a financial license.
