# Claiming Rewards The contract includes a function that allows a user to claim a reward for a successful assertion. This function checks if the challenge is closed for submissions. If this condition is met and the assertion is valid for a payout, a reward is sent to the user. --- # 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.
