Every physical artwork by Dutchtide is embedded with a cryptographic NFC chip — an ARX HaLo S1. The chip's public key is an Ethereum address registered at the moment of minting. No oracle. No intermediary. The chip is the proof.
01
Mint
Dutch embeds the chip and calls mintArtwork(). The chip's Ethereum address is permanently linked to the token on-chain.
02
Scan
Scanning the chip produces a cryptographic signature. That signature is used to verify physical possession — not a photo, not a certificate.
03
Transfer
Resale uses the same mechanism. The seller must sign with the chip to list. The buyer must scan to confirm delivery. The contract is the record.
