MasterStream · x402

Stop wasting time on 'expert' YouTube creators who hide their DAW project files. PAY-PER-STEP to unlock the internal routing, plugin chains, and MIDI logic of world-class producers. Every tutorial action—from viewing a specific compressor setting to downloading a stems package—requires a 0.01 USDC signed authorization. It’s a metered masterclass where you only pay for the insights you actually click on, proven by the instructor’s own cryptographic signature on the session data.

The primitive.

full primer →

Access to the tutorial authenticity 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 primitiveBy turning tutorial content into a metered stream of micro-transactions, we solve the 'lumpy' cost of education. Students don't pay $300 for a course; they pay cents to unlock the specific technical secrets they need, while instructors receive instant, frictionless liquid settlement for their expertise.

sample tracking
Provenance · x402
A sub-cent attribution layer for sound design. Producers pay $0.01 USDC to instantly unlock high-fidelity stems and secure a cryptographically signed provenance receipt. Every time a sample is previewed or dragged into a DAW, the facilitator settles a micropayment directly to the original creator's Magic Link email sign-in. No subscriptions, just pay-per-sample flow for the agentic music economy.
remix licensing
STEMS · x402
A 'Pay-per-Stems' protocol where remixers stream high-fidelity project files for 0.05 USDC per download. Every stem download triggers an immediate HTS transfer settlement to the original producer's wallet. Final remix uploads are gated by x402 signatures, ensuring the licensing fee is burned into the metadata before the track can be minted or played. licensing is no longer a contract; it's a micropayment primitive.
beat collaboration
BeatCommit · x402
A real-time rhythmic session layer where every MIDI pattern, drum hit, or sample flip is committed as a cryptographically signed stem. Producers pay 0.01 USDC to 'Drop' a loop into the shared master or 'Stem-Out' a high-quality bounce. Payments serve as the immutable proof-of-contribution, creating a financial trail of authorship that prevents ghost-producing and ensures royalty attribution at the primitive level.
