Backstage Ledger · x402
A cryptographic registry for legendary stage props where every provenance check, ownership transfer, and 'playbill' update costs 0.01 USDC. The app meters the history of theater history—enabling props to accumulate value through a chain of verified performance signatures. No subscription; pay per update to keep the legacy alive.
The primitive.
Access to the prop ownership engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so directors — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveBy turning ownership updates and provenance queries into x402 micropayments, the value of a prop is directly linked to its 'active' history. It prevents database bloat and ensures that only intentional, paid ledger entries create the prop's permanent lore, turning metadata into a financial asset.
