WCT in the After-Sales Service of Smart Home Appliances: Repair Records and Cost Settlement
In after-sales service for smart home appliances, fragmented repair records and disputes over cost settlements are common pain points. A certain home appliance brand applied WCT technology to establish on-chain repair files for each appliance, recording the causes of faults, replacement parts, repair personnel information, and more. After users report a malfunction, repair costs are settled using WCT, with cost details (such as parts fees and labor fees) available on-chain for verification. If the same fault occurs again shortly after repair, the smart contract automatically triggers after-sales guarantee clauses for free repairs or refunds. After applying WCT, the brand saw a 75% reduction in repair disputes, a 65% increase in customer satisfaction with after-sales service, and a significant improvement in brand reputation.
