# 4.3 3rd layer: Data utilization All application services that manage and utilize healthcare data through the LEMONCHAIN ecosystem belong to this layer, which includes metaverse environment operated in various environments including mobile, app and web, etc. Metaverse environment enables easy access to healthcare data within the data utilization layer and we are planning to provide SDK to make metaverse related service development easier and faster. If API and protocol to be disclosed with metaverse in the future is followed even if SDK is not used, it is possible to develop application service/program that can be linked with the LEMONCHAIN platform. Optimal UI/UX that enables users to conveniently record their data are provided in the metaverse environment. Moreover, community can be composed to allow natural execution of activities such as sharing of information and obtaining emotional supports through communication with other users. --- # 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.
