SHUTTERBAZE · x402

$0.01 — bid-to-view. Every bid placed on an auction requires a micro-payment to the artist/curator. This turns high-intent auction browsing into immediate revenue. Bidders pay per bid-entry to prevent ghost-bidding and bot spam, while private 'Dark Room' previews are gated by 1-click x402 signatures. All auction settlements and bid-increments are finalized via Hedera transaction ides, ensuring the photographer is paid for the attention, not just the final sale.

The primitive.

full primer →

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

Why this primitiveTraditional auctions suffer from non-paying bidders and zero revenue for the artist if the reserve isn't met. By metering the 'right to bid' and the 'right to view,' the photographer earns USDC for every interaction. x402 eliminates the friction of gas fees and manual approvals, making bidding feel like a low-stakes social game with high-stakes assets.
