How it works

From delivery to payment, in one verified loop

No new paperwork. The same delivery your team already makes becomes cryptographic proof — and proof is what releases the money.

The loop, live

Watch it run

Deliver01Verify02Auto-pay03

Deliver. IoT-tracked materials arrive; telemetry proves location, condition, and time.

Verify. Milestone rules check the evidence and commit the result to the ledger.

Auto-pay. The smart contract releases the milestone payment — no invoice chase.

Step by step

Four stages, one immutable record

Each stage writes to the ledger. Nothing is edited — history only grows.

01milestoneRules

Configure the milestone

Define acceptance rules once — geofence, temperature band, required evidence, telemetry reliability. This is the smart-contract config that will judge the delivery.

02telemetry.event

Capture the delivery

IoT devices stream telemetry as materials move. Crossing the site geofence in spec fires DELIVERY_CONFIRMED — proof of delivery as data.

03ledger.append

Verify on the ledger

The engine checks the evidence against the rules and commits a MILESTONE_TRANSITION to the append-only ledger. Verified, hashed, timestamped.

04payment.settled

Release payment

Verification triggers a PAYMENT_INSTRUCTION; the gateway settles and writes PAYMENT_SETTLED. The supplier is paid in seconds, not months.

Capture

Telemetry the field never has to think about

Devices confirm the delivery automatically. Your crew keeps working; the ledger does the bookkeeping.

Verify & pay

The ledger commits, the payment fires

Every verified milestone releases funds and appears here as a committed row — the orange sweep is money moving.
