VAULT · x402

A high-fidelity digital reliquary for the indie underground. Game jam creators lock their build assets and metadata into immutable storage using x402-native micro-bounties. Fans pay $0.01 per 'Play' or 'Download' to trigger a direct-to-creator settlement, ensuring projects stay alive and creators get paid per interaction long after the jam countdown ends. No subscriptions, just a meter on the culture.

The primitive.

full primer →

Access to the project preservation engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so game designers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitivePreservation is usually a cost center; x402 turns it into a revenue stream. By metering access at the sub-penny level, we solve the 'digital rot' problem while providing a friction-less tip jar that functions as a gate for high-bandwidth assets (builds/SFX packs).
