Run transparent auctions for rare photos secured and settled using Hedera testnet smart contracts.

The primitive.

full primer →

Auction platform gets a tiny Solidity contract deployed to Hedera testnet through the JSON-RPC relay; photographers see a 'verified onchain' badge with the live address and a one-tap HashScan link.

Why this primitiveBlockchain guarantees fair bidding and transparent settlement without intermediaries.
