Disclosed herein are various embodiments for blockchain service based application generator. An embodiment operates by determining a blockchain service configured to access, store, and receive updates to transactional data of the blockchain service. An enhanced data object including a wrapper with one or more additional properties corresponding to an original data object of the blockchain service is generated. The enhanced data object is transformed into a data protocol object. Metadata is generated based on the data protocol object. A data protocol service is generated based on the metadata. The application interface is configured based on the metadata, wherein the application interface is configured to communicate with both the data protocol service and the blockchain service. The application interface is provided to a user who is enabled to update the transactional data through the application interface.
