MasterNode · x402

A real-time 'revenue faucet' for music production. Instead of static NFTs, MasterNode meters every play or stem-download. Collaborators sign a multi-author HTS transfer manifest; users pay 0.01 USDC to unlock an isolated stem or high-fidelity playback. Every micro-transaction is instantly split and pushed to all contributors' Magic Link email sign-ins on-chain. Stop tracking rights — start streaming payments.

The primitive.

full primer →

Access to the co-creation tracking 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 primitiveLegacy music rights are bogged down by quarterly payouts and complex royalty math. x402 turns a song into a live API. By making the payment the access primitive, you ensure every contributor is paid at the millisecond of consumption, perfect for AI sampling and social sharing.

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.
