DOTCHECK · x402
A pay-per-verification registry for high-fidelity pixel art. Instead of gas-heavy minting, creators pay 0.01 USDC to timestamp a hash of their canvas, and collectors pay 0.01 USDC to instantly query the provenance API and verify authenticity. Payment acts as the cryptographic handshake between artist and ledger.
The primitive.
Access to the pixel art authentication 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 primitiveBy shifting from 'NFT Minting' to 'Pixel-Level Verification Calls,' we remove the friction of high gas fees and replace it with extreme-granularity micropayments. Every check of the art's history is a micro-transaction, turning provenance into a metered service for digital galleries and marketplaces.
