SONIC_LAYER · x402

Direct-to-ear artistic provenance. No subscriptions, no bundles—just 0.01 USDC to unlock a high-fidelity stem or visual layer. Listeners micro-pay to reveal the sonic architecture of a track, while creators earn instant settlement for every individual 'play' or 'view' event. Audio becomes a metered interactive canvas.

The primitive.

full primer →

Access to the integrated art & sound 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 one-time NFT mint to x402-metered access, the relationship moves from 'ownership' to 'continuous consumption.' It solves the liquidity issue of high-priced music NFTs by making the interaction cost negligible but high-frequency, creating a live stream of revenue for the artist.
