StemCell · x402

A pay-per-derivative engine where remixers buy 'Creation Rights' via x402 signatures. Every time a stem is downloaded for a remix, 0.01 USDC is instantly streamed to the original creator. The facilitator settles the permission on-chain, returning a transaction hash that serves as the legal 'license to flip.' Logic gates the high-res audio exports behind micropayments, ensuring the ledger of derivatives is automated and paid.

The primitive.

full primer →

Access to the remix management 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 primitiveRemixing is currently high-friction (manual clearance) or zero-value (bootlegs). By turning 'permission to remix' into a 0.01 USDC primitive, we monetize the long tail of bedroom producers and AI-sampling agents who need instant, verifiable rights.
