Challenge

Verify your signed challenge. You can sign your challenge using Metamask and our [signing tool](https://openformat-tools.vercel.app/).

Challenge verification

Trigger XP in your application when a user completes a specific action, such as registering, completing a task, watching a video or posting a comment. This is endpoint returns an [unsigned transaction](/architecture/transaction-lifecycle), which can now be signed in your application using your private key held in your local environment variables. Once signed, you can broadcast it using the [Execute Transaction](/api-reference/endpoint/transactions/post-transactionsexecute) endpoint; or if you prefer to wait for confirmation using the [Execute Transaction and Wait](/api-reference/endpoint/transactions/post-transactionsexecuteandwait) endpoint.
