CarChain

Overview

Blockchain-verified vehicle service history for the UK market — garages write tamper-proof service records to Polygon, so buyers can finally trust the logbook.

Used-car service history is missing, fabricated or lost every time a car changes hands. CarChain anchors each service record on the Polygon blockchain, where it can't be quietly rewritten: garages submit records automatically or manually and differentiate their business by doing so, owners build a verifiable history that survives the sale, and buyers get independent proof instead of a folder of receipts.
