🎵 Music & Sound Design · stem distribution

DECONSTRUCT · x402

A low-latency delivery layer for high-fidelity audio assets. Creators upload stems to decentralized storage; developers and remixers pay a per-track micropayment to fetch the raw stems directly into their DAW or AI-remixing agent. Each 0.01 USDC call triggers a real-time royalty split to the original producer and session musicians. No subscriptions, just pay-per-stem access for granular sampling.

The primitive.

full primer →

Access to the stem distribution 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 primitiveStem distribution is currently bottlenecked by high platform fees and 'all-or-nothing' subscription models. x402 allows for 'micro-licensing'—where an AI music generator or a bedroom producer can programmatically pull only the 'Drum' or 'Vocal' stem for a cent, enabling a fluid, usage-based creative economy.

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.
