PATCHLOCK · x402

Stop buying bulk packs to find one sound. DAW-integrated x402 plugins allow synth designers to monetize individual presets via HTS transfer. Producers pay 0.01 USDC to instantly 'patch-in' a premium sound to their session. No subscription, no bloated libraries—just a per-click logic that settles on Hedera, turning every 'Load Preset' action into a micro-royalty for the designer.

The primitive.

full primer →

Access to the synth programming 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 primitiveMicropayments solve the fragmentation of the preset market. Moving from a $50 bundle model to a $0.01 'pay-per-load' model lowers the barrier for producers while creating a high-volume, automated revenue stream for sound designers at the moment of inspiration.
