Sonic State · x402

A high-fidelity sound design vault where every template 'pull' is a micro-settlement. Designers publish reusable DAW racks, synth chains, and spatial spatial templates. Users pay 0.01 USDC to unlock a specific version or branch, with 100% of the fee routed to the verified author via HTS transfer. Payment is the atomic unit of provenance, ensuring authorship is cryptographically tied to every download.

The primitive.

full primer →

Access to the sound design templates 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 primitiveTraditional marketplaces have too much friction for single-asset downloads (high fees, cart flows). x402 enables a 'Pay-per-Preset' model that allows sound designers to monetize granular templates instantly without a subscription.
