Abstract: An electronic device is provided. The electronic device includes a communication module, a memory storing instructions, and at least one processor operably connected to the communication module and the memory, wherein the at least one processor is, by executing the instructions, configured to receive a request for execution of an application programming interface (API) from an application while driving the application, identify a policy for the execution-requested API based on data received from a decentralized network through the communication module, and determine whether to execute the execution-requested API, based on the identified policy for the API.
