Live on Robinhood Chain Testnet
Capital that moves with your cargo
USDG working capital for physical trade. Each tranche is released only when the shipment's own sensor evidence, committed on Robinhood Chain, says the cargo is fine.
See the route, the evidence behind every release and the money in escrow, live. No wallet needed.

Meet the people
Six people, one shipment
Trade finance is easier to follow as a story. These are the people in it, and every screen on this site belongs to one of them.
Meera
Exporter · Vaccines, Pune
Ships temperature-sensitive vaccines and gets paid in stages while the container is still at sea, instead of waiting months.
Daniel
Financier · Credit fund
Puts up the working capital. His money sits in a locked vault and is released only when the cargo's own sensor readings say it is fine.
Wei Lin
Buyer · Pharma importer, Singapore
Receives the cargo and pays the invoice once. That single payment repays Daniel and sends Meera the rest.
The Arbiter
Dispute resolution · Independent
Steps in only when the parties disagree, decides with the full evidence trail in front of him, and every ruling is on the record.
The Insurer
Parametric cover · Cargo cover
Sells cover that pays out automatically when the evidence shows the cargo spoiled, with no claim forms and no waiting.
The Carrier
Ship's officer · Bill of lading
Issues the digital bill of lading. Whoever holds that token controls the goods, so it can be locked to the loan that finances them.
How it works
One shipment, start to finish
Follow Meera's vaccines from Nhava Sheva to Singapore. Keep scrolling and each step plays out.
See the contracts behind each step01 · Meera, exporter
Meera registers her shipment
A 40-foot refrigerated container of vaccines leaves Nhava Sheva for Singapore. Meera sets the rule it must keep, 2 to 8 °C the whole way, and splits her financing into five milestones along the route.
Under the hoodThe route, the invoice and the cold-chain policy are stored on chain, and the contract enforces them.
02 · Daniel, financier
Daniel funds it, into a locked vault
Daniel puts up 40,000 USDG. It does not go to Meera yet: it waits in an escrow vault with one drawer per milestone, and nobody, not even CargoFlow, can send it anywhere else.
Under the hoodA shipment-specific escrow vault holds the USDG; only the release rules can move it.
03 · The data logger
The cargo vouches for itself
Probes inside the container sign every temperature reading. The readings are in range, so the first drawer opens and 8,000 USDG goes straight to Meera, while the ship is still at sea.
Under the hoodEvery 8 signed readings become one Merkle root on chain; score, sensor conflict and freshness are checked before a release.
04 · Off Sri Lanka
A warm reading pauses the money
Off Sri Lanka, the probe by the door reads 9.1 °C. Nobody has to notice or make a phone call: the next payment pauses on the spot, and everyone can see why.
Under the hoodAn out-of-range evidence batch flips the facility to Paused; no tranche can release until a verified recovery.
05 · The proof
A private proof clears it
The probe in the middle of the load stayed between 2 and 8 °C. A zero-knowledge proof shows exactly that without revealing a single reading. Meera gets a “Proof ready” alert, signs, and payments resume.
Under the hoodA Groth16 proof, bound to this exact pause, is verified by the contract itself.
06 · Wei Lin, buyer
Wei Lin pays once, everyone is settled
The vaccines arrive and Wei Lin pays the 100,000 USDG invoice. In the same moment the vault repays Daniel his 40,000 plus a 1,200 fee and sends Meera the remaining 58,800.
Under the hoodOne settle transaction runs a fixed waterfall: principal, fee, then the exporter's residual.
Settlement
One invoice, three payouts, no reconciliation
In the reference run a financier commits 40,000 USDG across five milestones at a 3% fee. When the buyer pays the 100,000 USDG invoice, the vault splits it in the same transaction.
- Exporter receives in total
- 98,800USDG
- Financier receives
- 41,200USDG
| Payout | Share | Amount (USDG) |
|---|---|---|
| Financier principal | 40% | 40,000USDG |
| Financier fee | 1.2% | 1,200USDG |
| Exporter residual | 59% | 58,800USDG |
The exporter already received the 40,000 USDG in tranches during transit; the residual tops it up to the invoice net of financing.
Portals
One facility, a portal for every party
Each party signs with its own wallet or passkey. Nobody, including CargoFlow, can move escrowed USDG anywhere else.
Exporters
Get paid while the cargo is still at sea
Register the shipment and its cold-chain policy, name your financier, and receive each tranche the moment its evidence is committed.
Meera draws 8,000 USDG at each of five milestones instead of waiting for the buyer.
- Gateway for your data logger
- Tranches per milestone
- Residual at settlement
Financiers
Lend against evidence, not paperwork
Fund a facility from your own wallet. Escrow releases only on committed, in-policy evidence, and an excursion pauses it until a proof clears.
Daniel's 40,000 USDG never leaves the vault unless the readings pass.
- Principal and fee first in the waterfall
- Optional default cover
- Portfolio view
Buyers
Confirm delivery and pay once
One payment settles the financier and the exporter in a fixed order, so there is nothing to reconcile afterwards.
Wei Lin pays one invoice and both Daniel and Meera are settled in the same transaction.
- See who receives what before paying
- One transaction
Arbiters
Resolve disputes and defaults
Rule on a disputed shipment with the evidence and the full audit trail in front of you.
The Arbiter only steps in when the parties disagree, and every ruling carries a public reference.
- Resume, lift a pause or declare a default
- Hashed, auditable decisions
Carriers
Issue and endorse bills of lading
Electronic bills of lading as ERC-721 titles, bound to the facility they finance.
The Carrier issues the bill; whoever holds it controls the goods, and it can be locked to the loan.
- Issue from the document's fingerprint
- Endorse and surrender
