Why on-chain
A certificate issued by a shop and hosted on the shop's server proves nothing beyond the shop's own database. An anchored hash proves the record existed at a point in time and has not been edited since. That is a narrow claim, and we only make that one.
Phase 1 anchors are signed and published; on-chain writes go live after the audit. Certificates issued now remain verifiable and will be re-anchored, not reissued.
Connect a wallet
Sign a one-time message with your wallet. No transaction, no gas, no private key ever leaves your device. The signature proves you control the address.
Claim a version record
Every product has a version record: which painting, which source file, which print run. When a run is closed the record hash is anchored, and anyone holding the code on the pack can resolve it.
Verify independently
Anyone can paste a certificate code and check the anchor. No account, no wallet, no permission needed — the point of the record is that it does not depend on trusting us.
样例记录

- Issued
This record confirms which file the print was made from and that its hash was anchored on-chain. It is a provenance record for a reproduction — it does not make the print an original, a limited edition or an investment.
