Response

Introduction

The Response module is a vital part of any request that manages the requirements the requester has for the proposers, such as holding an NFT, being in a pre-defined list of addresses or providing a bond, and pays out the rewards for accepted responses.

Prophet's Response modules:

• BondedResponseModule that requires a proposer to post a bond first, which will be returned upon request finalization or slashed in case of a successful dispute.

Creating a Response Module

To build a Response module, simply inherit from IResponseModule and the Module abstract contract, create the RequestParameters struct and define the logic for proposing, deleting and finalizing responses.

A Response module should take care of the following:

• Defining the criteria for proposers to be able to answer the request
• Setting the rules for the responses, such as validations or deadlines
• Handling the rewards for proposing a valid response
• Applying the onlyOracle modifier to the hooks to secure them
• Releasing the bond if the response ended up being unutilized, meaning it's not accepted nor disputed

While developing a Response module, keep in mind that the criteria that is too narrow might result in a lack of responses, while criteria that is too broad might result in a large number of invalid responses.
