StemCell · x402

Turn your DAW into an automated clearinghouse. Every time you drag a loop into a project, trigger a $0.01 x402 signature that verifies the sample's cryptographic origin and instantly settles a micro-royalty to the original sound designer. No more licensing guesswork—pay-per-pull provenance that protects creators and clears producers for commercial use in one click.

The primitive.

full primer →

Access to the sample lineage 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 shifting from a static database to a pay-per-use 'verification event,' the app turns provenance checking into a frictionless, high-volume transactional primitive for the music industry.

Loop Provenance

Track and verify origin of audio loops to ensure authenticity for musicians and producers.

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.

sound libraries

FoleyStream · x402

A high-frequency granular sound library where every 'Listen' and 'Download' is a streaming 0.01 USDC micro-settlement. Sound designers monetize individual transients, hits, and textures without subscriptions. Creators pay-per-sample to bypass licensing friction, while AI music generators use the API to pull stems in real-time. Direct HTS transfer settlement ensures the Foley artist is paid before the audio buffer even finishes playing.
