# Signing and Broadcasting Transactions Once an account is authenticated against an application, the latest can request the user to sign and broadcast transactions. The user has the guarantee that the transaction requests come from the application with which he has just authenticated because both the app and the user have created a strong link through the authentication process and the **HAS** will filter out any transaction request from an unapproved application. Similar to authentication, users will be able to approve or reject each transaction request that the approved applications will submit to them for signature. --- # 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.
