Open Origin Passport
A verified origin passport for every bag.
Source Loop connects each bag of coffee to the lot it came from, the farmers who grew it, and the institutions that handle it along the way. Scan the QR on any Source Loop bag and the passport opens on your phone.
What you scan
One bag, one passport, one chain.
Every Source Loop bag carries a QR that resolves to a unique passport for that specific lot. The passport shows the origin, the producers, the processing, the cupping, the roasting, the verification level on each claim, and the institutions registered against the chain. Nothing is anonymous. Nothing is generic. Each bag is its own record.
How verification works
We show what we know, and how we know it.
Every claim on a Source Loop passport carries a verification level from L1 to L5. The same claim can move up the ladder as evidence accumulates. The level shown is the level we can defend.
- L1Self-declared. Stated by the partner, no third-party check.
- L2Field-agent captured. Recorded in person, on site, by a Source Loop or partner field agent.
- L3Cooperative-confirmed. Confirmed by the producer cooperative with operational evidence on file.
- L4Document-supported. Backed by a primary document such as a roast record, contract, or certification.
- L5Third-party verified. Cross-checked against an independent dataset or audit body.
The current Sigararutang lot from Wanoja Farms is verified deforestation-free at L5 against JRC Global Forest Cover and Hansen tree-cover-loss data through WHISP.
Partner registry
The institutions behind the lots.
Every cooperative, processor, and roaster on Source Loop has its own registry profile. The profile shows when they joined, what role they play, what they are currently verified on, and the lots they have shipped under the system. Bag passports link to registry profiles so each lot is traceable to a specific batch and to the institution that anchors the chain.
EUDR readiness
Built for the EU deforestation rules.
Source Loop captures the origin, geolocation, plot size, and deforestation evidence that the EU deforestation regulation requires. Buyers can review the data lot by lot before they purchase. Producer-side data is held under disclosure controls so commercially sensitive details stay protected even where due diligence is satisfied.
For buyers, that means due diligence inputs are ready when the bean is. For producers, it means compliance does not require giving up confidentiality.
Pilots and active chains
Where Source Loop is operating today.
Source Loop is live on Indonesian coffee through Wanoja Farms in West Java, covering both arabica from Kamojang and robusta from South Sumatra. A second pilot is in setup in Uganda, in partnership with a global green coffee trader and a coffee hardware and AI partner. The pilot is structured around in-country quality control, plot-level data capture, and EUDR-ready handover into the European supply chain.
New origin chains are added by partner registration. If you operate at any link in the chain and want to be on the system, contact us.
How the proof layer works
Tamper-evident by design.
Source Loop passports are anchored to a public proof layer. Each passport publication writes a record to Sui with the underlying evidence bundle stored on Walrus. The anchor lets anyone confirm when a passport was published and whether the record has changed since.
Current passports show demonstration anchor values while the production anchoring pipeline is being finalised. The verification data above the anchor section is live.
