How do I link my X account?

Some reward campaigns pay you for posting about a collection on X and claiming through Unvault. To take part, open the campaign page and choose Link X; you will be sent to X to authorise read access to your public posts, then returned to Unvault.

Linking lets Unvault confirm that a post exists and carries the required disclosure. It does not let Unvault post for you. You can unlink from your profile settings or from X's connected-apps page at any time.
