# General Data Events are triggered to communicate between smart contract transactions and user interfaces. By connecting DApps to Ethereum JSON-RPC API, you can listen to events to trigger specific actions. Events can be used in different ways: 1. Returning values for a user interface 2. Asynchronous triggers with data 3. A cheaper form of storage The information is communicated from a smart contract event to a user interface via logs. Logs are helpful for debugging smart contracts and for making analytics dashboards. --- # 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.
