🎵 Music & Sound Design · credit attribution

LinerNote · x402

A global, high-fidelity attribution layer where metadata is a paid event. Instead of static lists, media players and streaming protocols ping this ledger to verify and display the 'Credit Layer' of a track. Each micro-payment of 0.01 USDC triggers a signed event on Hedera that immutably proves a composer's contribution and immediately routes a fraction of the fee to the credited wallet. Truth as a service for the music industry.

The primitive.

full primer →

Access to the credit attribution 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 'viewing credits' into a sub-penny transaction, you solve the 'orphaned works' problem. Creditors are paid per verification call, and platforms gain a tamper-proof audit trail for royalty payouts via Base transaction hashes.

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

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.
