The HeFi project is a digital platform that integrates health and finance, mainly targeting the elderly. It leverages blockchain, digital technology, wearables, artificial intelligence and robotics to support healthy aging and continued community living. Users can manage wearable devices through the app and earn HeFi tokens through community participation, which can be used to purchase goods and services on the platform. The platform also facilitates healthcare management, allowing users to monitor their health status and access medical services, ensuring privacy and data control through decentralized identifiers (DID) and NFT technology.
