Four products.
One collateral base.
Storage is the entry point. Lending monetises the receipt. Leasing monetises the beans. Savings monetises the term structure. All four run on the same batch passport and the same daily valuation.
Vault storage
Batch-level storage at 18°C and 55% relative humidity, with a retained sample sealed for 18 months. Every position is tagged against the batch passport so the goods and the record cannot drift apart.
Warehouse-receipt lending
Borrow against a registered receipt at a ratio derived from VaR. Daily revaluation, automatic margin call at 60%, liquidation at 72%. The goods never move without a discharge instruction from the lender.
Bean leasing
A roaster takes beans out of the vault without buying them, pays a monthly lease fee on the value drawn, and returns an equivalent lot of the same origin and grade. Inventory becomes a service instead of a balance-sheet item.
Bean savings
Deposit three tonnes or more for six months and storage is waived, with bean interest paid in kilograms because the position can be leased out. Withdraw the same origin and grade, or take the cash equivalent at valuation.
The roaster's problem is not the price of coffee. It is the timing.
A roaster buys twelve weeks of beans, roasts them over twelve weeks, and gets paid on delivery. For the first six weeks it is financing inventory it has not sold. Leasing removes that gap — the cost becomes a line item that moves with volume, not a capex commitment.
| Term | Lease fee / month | All-in annualised | Typical use |
|---|---|---|---|
| 1–3 months | 0.60% | 7.2% | Bridging a shipment delay |
| 3–6 months | 0.90% | 10.8% | Seasonal menu build-up |
| 6–12 months | 1.15% | 13.8% | Forward-priced retail contracts |
Compare against the alternative: a working-capital line at 8–10% plus ¥0.20/kg/month storage plus the risk of holding the wrong grade. Leasing is not cheaper on paper — it is cheaper once you price the option to return the beans.
A state machine, not a document
Every receipt moves through exclusive states. A receipt cannot be pledged twice because the system rejects the second request — not because someone promised to check.
Dashed path: settlement failure returns the receipt to pledge. Every transition writes an immutable event with actor, timestamp and document hash.
