Provenance log
Permanent provenance is created
Your piece gets a unique Sannend ID, a tamper-proof record anchored to a public blockchain, and a shareable provenance page — all automatic.
Anyone can confirm authenticity
Buyers, insurers, or auction houses can verify any certificate or Sannend ID in seconds. No account required. No phone calls. No lab business hours.
Why Sannend
We don't sell collectibles or compete with labs. We're the verification layer that makes the entire market more efficient.
Authenticate any certificate in seconds. No phone calls, no lab business hours, no re-certification fees. Just the truth, instantly.
Try verification →Every examination, transfer, and attestation becomes a permanent, tamper-proof record. Provenance that survives generations — not just the next sale.
Register a piece →Sannend doesn’t sell, appraise, or certify. Like Carfax for vehicles, we’re the independent layer that everyone can trust — buyers, sellers, labs, and insurers alike.
See how it works →“We use blockchain the way banks use it — as infrastructure for security and permanence, not as a speculative asset.”
Think Stripe for payments. Carfax for vehicles. Sannend for provenance.
No account required. Enter a certificate number or Sannend ID and know immediately whether it's authentic.
