On-chain verification
Verify certificate
Check the authenticity of any certificate issued on Tessera. We verify the SBT status directly on the blockchain, and the contract stores on-chain which institution issued it: if Tessera disappeared, the certificate would still say who granted it.
On-chain verification
Verify certificate
Check the authenticity of any certificate issued on Tessera. Choose one of the three methods: enter the transaction hash, upload the certificate (image or PDF) with its QR, or scan it directly with your camera.
How verification works
- 01
Get the ID
Every certificate has a unique Token ID. You will find it on the certificate, the badge or in the verification URL.
- 02
Verify on-chain
We query the smart contract to confirm the SBT exists, who issued it and that it has not been revoked.
- 03
Independent validation
You can check it yourself in the explorer with the transaction hash. You do not need to trust Tessera.
