Resonance · x402

$0.01 — pay-per-audition. A high-fidelity sonic library where creators earn instantly on every preview and download. No subscriptions, just a micro-settlement for every drum hit, synth stab, or vocal chop streamed via Base. All usage rights are baked into the transaction metadata, with HTS transfer ensuring zero-friction acquisition for bedroom producers and AI-music agents alike.

Section · Onchain

The primitive.

full primer →

Access to the sample exchange 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 'swapping' to 'metered access' eliminates the double-coincidence of wants. By pricing previews at $0.01, creators monetize the curation phase, not just the final sale.

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.
