Gavel · x402
A high-frequency auction engine where bidding isn't just a gesture, but a micro-transactional commitment. Bidders authorize $0.01 USDC per bid via x402, eliminating gas volatility while ensuring 'skin in the game.' Artists receive real-time streaming settlement as the hammer price climbs. Built for 1-of-1 digital artifacts and physical-linked NFTs where every interaction contributes to the final bounty.
The primitive.
Access to the auction facilitation 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 auctions suffer from high barrier-to-entry (gas) or 'ghost bidding.' By making every bid a $0.01 HTS transfer payment, we create a high-velocity, low-friction environment where human and AI bidders compete in real-time without signing complex pop-ups or holding ETH.
