What is UNTP?
The UN Transparency Protocol (UNTP) is a UN/CEFACT standard for sharing verifiable supply-chain information across organisations and borders. Instead of PDFs and spreadsheets, participants publish machine-readable digital credentials that any buyer, regulator or customs authority can verify independently.
Mineliqo publishes four UNTP credential types for your batches: the Digital Product Passport (DPP), Digital Facility Record (DFR), Digital Traceability Event (DTE), and an identity resolver linkset that ties them together.
Every credential is signed
Mineliqo signs each credential with an Ed25519 key belonging to the organisational identifier did:web:mineliqo.com. The matching public key is published at https://mineliqo.com/.well-known/did.json, so a verifier can confirm the credential came from Mineliqo and has not been altered.

- Issuer: did:web:mineliqo.com
- Each credential also declares the issuing software version for the UN/CEFACT Software Implementers Register
Where to find your credentials
- Open the public verification page for a batch (the QR code on any shipment).
- Use the UNTP JSON-LD links to open the signed passport, facility record or event.
- Paste any credential into the UNTP test playground at test.uncefact.org to verify it independently.
Canadian extension
Canadian critical-minerals fields — province, mine name, extraction date, CO₂e per tonne and Towards Sustainable Mining scores — are published as a registered UNTP extension under the mineliqo: namespace, so core UNTP verifiers ignore them safely while Canadian buyers and regulators can read them.
