The app will verify it before allowing you to proceed with the rest of the onboarding flow. Only new Rhoers are eligible to join with a referral code. If you have already joined Rho World, you will not be able to input a referral code retroactively. Your Referral Code Upon joining Rho World, you will automatically receive a unique referral URL and code. Feel free to share this with your friends to encourage them to join Rho World using your code. --- # 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.
