Refund-by-Location-dApp
Introduction
This project is aimed to be used when one party, for example an employer, agrees to pay another party, for example an employee, for being present in a certain geographic area for a certain duration. The employee’s phone sends its GPS location to a smart contract at a certain interval. Based on the pre-agreed contract codified in an Ethereum smart contract, a cryptocurrency payment is executed when all the agreed conditions are met.
If, at any point, the GPS sensor indicates that an employee is outside the range of the agreed GPS area, the contract state will be updated to indicate that it is out of compliance. The GPS data will be gathered from the participant's phone sensor through a companion mobile app. The app will not require much interaction once it is installed. The app will be running in the background and will send out the location randomly throughout the duration.
Requirements
This project requires Flutter for mobile app and admin panel and Truffle for the smart contract.
