Here is a short list of them: * Deploying new option token contracts * Liquidating expired option token contracts * Calling prefetch functions for updating contracts preprocessed parameters values (ex: daily price volatilities) to reduce traders gas usage * Monitoring collateral requirements for performing early liquidation of undercollateralized options writers open positions Upon successfully executing one or more of these tasks a validator will be rewarded with **Defi Options** governance tokens, which he/she could exchange for their monetary value, or accumulated for having a say in the governance process. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.defioptions.org/protocol/roles/validators.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
