# ChainLink integration Chainlink will be used as an oracle service to connect external data to smart contracts that manage warranties. For example, when a user reports a defect, the smart contract can use the Chainlink oracle to check the status of the product (purchase date, registration, service status) outside the blockchain - e.g. from the manufacturer's database or service system. Chainlink will also enable automated fulfillment of warranty conditions based on real-world data (e.g. that the device was actually sent for service, that the defect was confirmed, etc.). This further secures the DEXPIRY token warranty system against fraud and increases reliability without a central intermediary. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
