MasterStem · x402

Pay-per-trace live set archival. Performers trigger a 0.01 USDC x402 call to timestamp and immutable-store a loop buffer or stem directly from their DAW. Fans and producers pay 0.01 USDC to unlock high-fidelity stems for remixes, with immediate settlement to the artist. Total provenance for the modular age.

The primitive.

full primer →

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

Why this primitiveTraditional cloud storage is a subscription sunk cost; x402 turns every 'Save' and 'Export' into a micro-transactional proof of creation, enabling a pay-as-you-go marketplace for raw live elements.
