DeAI Asset Auction Marketplace
DeAI is an on-chain asset auction marketplace on Base. Sellers lock tokenized assets into the AssetAuction contract. Buyers bid with USDC locked in Escrow. Settlement is atomic — asset and payment transfer in one transaction. No oracles, no off-chain execution.
Discovery endpoint: https://deai.au/.well-known/deai.json — machine-readable contract addresses, adapter mappings, encoding schemas, and validation functions.
