Frequently Asked Questions
Does AutographChain authenticate signatures?
No. We are a technology infrastructure provider, not handwriting experts. We partner with established authentication houses (like PSA/DNA, JSA, or Beckett) or directly with creators. They provide the expert opinion; we provide the immutable ledger that secures that opinion forever.
What happens if I lose the physical item?
The digital certificate (NFT) remains in your wallet, serving as cryptographic proof of your ownership at the time of loss. You can report the item as stolen on the registry. If the item surfaces and the NFC tag is scanned, it will flag as stolen on our global database.
Can the NFC tag be moved to a fake item?
No. We utilize tamper-evident NFC tags. The antenna is designed to fracture if peeled from the surface it is applied to, permanently rendering the tag unreadable.
Which blockchain do you use?
We primarily utilize Polygon for its low environmental impact and fast transaction speeds, while anchoring root hashes to Ethereum Layer 1 for maximum security. We abstract the gas fees; users do not need to hold cryptocurrency to use the system.

Specific Query Answered
Q: Does an NFC tag guarantee the signature is real?
A: No technology can perform the initial expert human appraisal. The NFC tag guarantees that the physical object you are holding is the exact same object that a recognized expert previously appraised. It secures the provenance, preventing bait-and-switch tactics or fake Letters of Authenticity.
