Finality

Introduction

Finality modules are responsible for executing actions when a request is finalized, such as notifying a contact about the response to a request.

Prophet's Finality modules:

• CallbackModule sends a predefined callback to an external contract.
• MultipleCallbacksModule that is similar to the CallbackModule but allows for multiple callbacks to be sent.

Creating a Finality Module

To build a Finality module, inherit from IFinalityModule and the Module abstract contract, create the RequestParameters struct and define the logic in the finalizeRequest function. Most importantly, make sure to handle the finalization with and without a response.
