कवच · Kavach means armour
Kavach is an open freight exchange for India's dangerous goods. Shippers post loads of liquid oxygen, ammonia, chlorine or acid. Only transporters whose tanker, driver and licences pass the compliance gate can bid. Every trip is tracked, and every action is written to a ledger that can't be quietly edited.
Free to register during the pilot. Companies are verified (KYC) before they can post or bid.
The problem
A plant that needs a cryogenic tanker tomorrow calls the transporters it knows. Nobody checks whether the PESO licence on file expired last month, whether the driver's hazmat training is current, or whether the GPS unit actually works. Tankers drive hundreds of kilometres back empty because no one knew a load was waiting near the drop point.
General freight apps don't solve this. A cryogenic tanker can't carry cement on the way back, and an acid tanker can't carry LPG. Matching hazardous freight means matching the right vehicle class, the right paperwork and the right driver, every time.
How it works
Choose the product by UN number, pickup and drop hubs, tonnage and date. Kavach names the vehicle class it needs and shows a benchmark rate per tonne-km.
Each transporter's vehicles are checked against the load: class, capacity, PESO licence, fitness, driver training, TREM card and AIS-140 GPS. A vehicle that fails any check can't bid.
Bids are scored on price, empty distance to pickup, rating and on-time record. Bids below half or above one and a half times the benchmark are refused. Transporters never see rivals' prices.
GPS fixes move the trip across the map. An impossible jump holds the trip for review. Delivery is accepted only within 25 km of the drop hub.
Try the compliance gate
This runs the same seven checks Kavach runs on every bid, using example vehicles. The gate runs again when a load is awarded, because documents expire between a bid and an award.

What moves on Kavach
Every load carries its orange ADR plate: the hazard identification number on top, the UN number below. Kavach uses both to decide which tankers may bid.
Value for each side
An estimate from your own inputs, not a promise. The transporter figure assumes every return trip runs empty today and an operating cost of ₹55 per empty km.
Control tower
Operators approve each company's KYC, watch live trips across India, release trips held for GPS anomalies and verify the audit ledger in one click. Updates arrive over a live connection, not a page refresh.
Example alerts. Registrations are fictional.
Security and trust
Passwords hashed with PBKDF2-SHA256. Authenticator-app two-step sign-in, mandatory for operators. Lockout after repeated failures.
Every query is scoped to your company from a signed session. Rival transporters never see your prices, documents or people.
HTTPS everywhere with HSTS. Two-step secrets encrypted with AES-256-GCM. Documents stored encrypted at rest.
Every post, bid, award, hold and document view is appended to a SHA-256 hash chain. Changing any past record breaks the chain.
Duplicate vehicle registrations refused. Out-of-band bids refused. Impossible GPS movement holds the trip. Uploads checked by file signature.
Designed around India's Digital Personal Data Protection Act, 2023. Strict content security policy and no third-party trackers.
Roadmap
Register your company, complete KYC, and post or bid on your first hazardous load. Registration is free during the pilot.
