The Verified Loop · Construction supply chain
Delivered. Verified.Paid.
on an immutable ledger — automatically.
ChainBuild360 turns construction delivery into proof. IoT-verified milestones commit to a tamper-evident ledger, and supplier payment releases the moment the work is confirmed — no invoice chase, no dispute spiral.
Built for the firms, suppliers, and PMs who move $13.6T of construction a year — and wait months to get paid for it.
The loop
Deliver → Verify → Auto-pay
One closed loop replaces the paper trail. Materials arrive and prove themselves; the ledger verifies; the contract pays. Watch it run.
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.
Deliver
Delivery capture, straight from the field
IoT devices ride with the shipment and stream location, temperature, humidity, and shock in real time. When materials cross the site geofence in spec, the delivery confirms itself.
Proof of delivery becomes data — not a scrawled signature on a clipboard that disappears by month-end.

Verify
On-chain verification you can watch commit
Milestone rules evaluate the evidence and write the outcome to an append-only ledger. Every block is timestamped, hashed, and impossible to quietly edit.
Each verified milestone commits with an orange sweep — the moment the network agrees the work is real.

Pay
Automatic payment release
The instant verification lands, the smart contract releases the milestone payment to the supplier. Statutory holdbacks are respected; everything else moves at the speed of proof.
This is the payoff — the single orange event the whole platform is built around.

The opportunity
A trillion-dollar industry still paid on trust and paper
Construction is one of the largest — and least digitized — sectors on earth. Verified settlement is the missing layer.

Platform
Seven capabilities, one verified loop
Everything here serves the same idea: make delivery provable, and let proof drive payment.
Tamper-evident transactions
Every delivery, verification, and payment is written once to an append-only ledger. Nobody edits history — they extend it.
Smart-contract milestone automation
Encode acceptance rules once — geofence, temperature band, evidence — and let the milestone settle itself when they're met.
Real-time IoT tracking
Device telemetry streams location, temperature, humidity, and shock so the proof of delivery is data, not a signature.
Supplier verification
Verified supplier identity and performance history travel with every purchase order across the network.
Faster dispute resolution
A shared, timestamped record means disputes are settled against evidence in hours, not adversarial weeks.
AI demand & inventory analytics
Forecast material demand and inventory risk from live project and telemetry signals before a shortfall becomes a delay.
Sustainability tracking
Trace material provenance and embodied-carbon data through the chain to support ESG and procurement reporting.
Why blockchain
Not crypto. A shared record no single party can rewrite.
When the general contractor, the supplier, and the PM all read from the same tamper-evident ledger, the argument stops being “whose paperwork is right” and starts being “what the evidence says.”
Why it has to be a ledgerdeliver — verify — pay
Close the loop
Deliver it. Verify it. Get paid for it.
We’re onboarding a small pilot cohort of construction firms and suppliers in 2025. Bring us a delivery-and-payment headache worth solving.
