EUDR Traceability
Chain the origin, harvest date, and permit attributes required by EUDR through ZK attestations across the supply chain, verifying them tier by tier without sharing any raw production records.
For EUDR-covered businesses
Carrying EUDR due-diligence liability for upstream chains you can't fully see, resolved by provenance you can verify back to origin.
-
Procurement and trade-compliance leads at EU-bound exporters of coffee, cocoa, palm oil, soy, rubber, beef, or timber
-
Cooperatives and traders aggregating producer-side data across smallholder networks
-
Importers carrying EUDR due-diligence liability on shipments composed of upstream they don't directly contract with
Hand over the source, or just the facts?
Nothing changes on the floor. Everything changes for the receiver.
① Your team just saves, as always.
- The usual step
- Fill in the record and save
- On save
- A proof is attached (API, behind the scenes)
- The document itself
- never sent
② They just open a link.
- Proven fact
- meets EUDR origin, harvest-date and permit attributes
- supplier raw records and transaction data
- not shown
- Login / keys
- not needed
- The document stays private — the record itself is never sent or disclosed.
- Independent verification — the receiver just opens a link. No account, no keys.
- Edits are detected — even a one-character edit fails verification.
Each tier of the chain — the producer (or the cooperative aggregating producers), the trader, the importer — issues an attestation against the EUDR-specific attributes: country of origin, geolocation polygon, harvest date, permit status, deforestation-free indicator measured against the regulation's reference date.
The attributes are signed against each holder's source data — the producer's plot data, the cooperative's aggregated records, the trader's chain-of-custody — and the proof reveals only the attribute, never the source. The importer's final due-diligence statement is a single composed ZK proof, not a folder of supplier-side spreadsheets.
For multi-smallholder chains, the cooperative pattern handles aggregation without forcing each producer to expose their plot data downstream. A producer can withdraw or update an attestation without rebuilding the chain.
Why the usual methods fall short.
Only work that needs all three at once — pass without exposing, independent verification, tamper-evidence — is Lemma's domain.
| Method | Pass without exposing | Independent verification | Tamper-evident | What happens |
|---|---|---|---|---|
| Access control / permissions | △ | ✗ | ✗ | “Someone inside could have edited it” remains possible |
| Masking / redacted copies | △ | ✗ | ✗ | Redaction work grows; the original is still unproven |
| Encrypt and store / send | ✓ | ✗ | ✗ | To verify, the receiver needs it disclosed after all |
| Lemma (ZK proof)the only one with all 3 | ✓ | ✓ | ✓ | The receiver just opens a link |
