Pedigree · x402

Lineage as an automated ledger. Using x402, artists charge a micro-fee for every 'Influence Signature' granted to a student. Each payment triggers a cryptographically signed proof of mentorship that the student displays in their digital portfolio. Influence is no longer a vague claim; it is a metered, verifiable bond between master and apprentice settled on-chain.

The primitive.

full primer →

Access to the art mentorship proof engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so painters — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveTraditional mentorship is opaque and rarely compensated. By making the 'stamp of approval' a pay-per-use transaction, we create a quantifiable influence graph where mentors earn passive USDC for their reputation and students get immutable proof of study.
