DandaLink — carry provenance from stump to export container.
MidziLabs records the lineage of the living tree. DandaLink proves the timber: it ties every board back to a geolocated harvest plot, validates it against the EUDR baseline, and renders the Due Diligence Statement EU customs legally require.
The forest is geolocated. The supply chain forgets where the wood came from.
A concession knows its harvest plots to the metre. But the value chain needs proof all the way to the export container — and the chain breaks at the mill, where logs from many plots are pooled, sawn and re-packed into batches and products. From the EUDR application date, EU importers cannot legally place timber they cannot trace back to a deforestation-free plot, harvested after the 31 December 2020 cut-off. That break is where export access is stranded.
- Origin is known at the plot — then pooling at the mill erases it.
- Many plots become logs, batches, consignments and containers.
- DandaLink preserves a verifiable link across that aggregation and split.
One chain of custody, one statement customs can verify.
Bind the timber to its plot once, across the split — then render the archival statement an EU importer and a customs officer can check, from that single source of truth.
Ingest · any source
Consumes geolocated harvest plots, species and harvest dates from whatever a country runs — GIS exports, concession registries, or MidziLabs — through a pluggable adapter. Bulk CSV import is all-or-nothing: one bad row and nothing persists.
Bind · plot → product
Links the harvest plot(s) to the felled log, milled batch, consignment and container — an unbroken path from any exported board back to every contributing plot. That chain-of-custody integrity is the product's moat.
Emit · the DDS
From that one binding, renders the EU EUDR Due Diligence Statement as archival PDF/A-3b — carrying the plot geolocation set and post-2020 attestation, ready to file in the EU information system.
Verify · at the border
Every statement is structured and self-describing — a customs officer or importer validates the origin set without trusting the exporter's word, reusing the same public-verification pattern as the rest of the family.

Built outside the registry, on purpose.
DandaLink is a commercial integrator, deliberately built outside any sovereign registry. The timber operator owns its own data; DandaLink connects through the same open API as any other vendor, with no privileged access. It runs multi-tenant on Postgres row-level isolation — every operator's plots, batches and statements are walled from every other's.
- Commercial B2B SaaS — the operator owns its data, not the platform.
- Registry-agnostic: GIS, concession registries, MidziLabs — never locked to one.
- Never a national registry, never a sovereign-data custodian.
MidziLabs records the roots; DandaLink proves the timber.
What LITS is to METS, MidziLabs is to DandaLink — the lineage registry beneath the forestry and agri-genetics vertical.
The living lineage
A germplasm registry for plant genetics: accessions, recursive pedigree trace and idempotent phenotype observations captured in the field, online or offline. The provenance of the living tree, below ground.
The harvested timber
Picks up where the tree is felled: chain of custody from plot to container, EUDR validation and the archival Due Diligence Statement — the provenance of the product, above ground.
Registry → integrator
The same shape the family already runs for livestock — a neutral registry under sovereign or commercial control, and a vendor-neutral integrator on top — applied to a new commodity.
DandaLink builds the verifiable evidence base and files the operator's statements. It does not grant a country market access or certify a forest as legal — those remain sovereign, regulatory programmes. DandaLink makes the proof; the authority and the importer decide.
