Karvia

Vehicle history,
verifiable

Give the vehicles on your platform a history that travels with them — it does not stay in your database. Health, documents, and services stay verifiable (on blockchain).

Why the passport matters

A vehicle with a verifiable history is worth up to 15% more

Buyers do not trust the seller’s word. They trust data nobody can alter. A blockchain Vehicle Passport turns every service, every trip, and every inspection into immutable proof that travels with the vehicle — not with your database.

Higher resale value

Every on-chain attestation shows the vehicle was looked after. A health figure of 85/100 backed by a verifiable history creates instant buyer confidence.

On-chain compliance verification

Portable, it lives on-chain

The passport does not live in our database — it lives on Stellar. If your platform shuts down, the passport still exists. Anyone can verify it from the web without an account.

NFT on Stellar = owned by the vehicle owner
Verifiable by any third party

Continuous certification

This is not a one-time inspection — it is a living certification that refreshes every 48 hours with telemetry, service, and driving data.

Standards and compatibility

We accept OBD data, GPS, and CAN telemetry and normalize readings into an operational health figure. We do not claim ISO 20078 (ExVe) certification today.

ISO 20078 (ExVe)

Not a Karvia certification today. OEM data via ExVe is a future path, separate from the aftermarket dongle.

SAE J1939 / J1979

OBD-II and CAN protocols for passenger and heavy-duty vehicles. Fault codes and live readings — protocol vocabulary, not an SAE certification of the Karvia product.
