SonicDebit · x402

A granular audio boutique where every 'Save As' or 'Export' triggers a $0.01 settlement. Instead of bulky licensing contracts, creators pay per-sample-layering or per-stems-access. Metadata is signed by the facilitator, providing an immutable proof-of-payment hash that serves as your global usage license.

The primitive.

full primer →

Access to the asset marketplace 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 primitiveMoving from NFT ownership (high friction, high cost) to micropayment-based licensing (low friction, high volume) enables 'pay-as-you-compose' workflows. It eliminates the 'all-or-nothing' subscription model, allowing bedroom producers and AI music agents to license specific snares or synth patches on-demand.

Sound Asset Licensing

Streamline sound asset licensing with minting provable NFT ownership tokens.

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.
