STEMS · x402

A high-fidelity sound library where every 'Download' or 'Drag-and-Drop' is a 0.01 USDC primitive. Eliminate bulky subscription tiers and legal ambiguity. Producers pay per-snare or per-loop via a signature; the x402 facilitator handles the license issuance on Hedera. The HTS transfer signature acts as the timestamped proof-of-rights, instantly settling royalty splits to the original sound designer.

The primitive.

full primer →

Access to the sample rights 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 turning the 'license' into a sub-penny transaction, we remove the friction of traditional sample packs where users pay $30 for 100 sounds they don't want. The x402 model enables 'surgical sourcing' for DAW users.
