# Referral FAQs ### 1. **How do I invite friends to join Market.Cards?** You can find your 8-digit invite code and invite link on the Referral page. You can share your invite code, invite link, a platform-generated invitation image, or a card sharing image with friends. If a friend registers through your invite link, or enters your invite code in the designated entry point, they will usually establish an invitation relationship with you. Whether the binding is successful is subject to what the platform page displays. ### **2. Can an invitation relationship be changed or removed?** Usually, no. Each user can generally bind only one inviter. Once an invitation relationship is established, users cannot manually remove or modify it. If a user does not trade for more than 30 days after binding an invitation relationship, that invitation relationship will still be automatically removed under platform rules. After automatic removal, the user also cannot bind any inviter again, including the original inviter. The specific status is subject to what the platform page displays and the applicable rules. ### **3. Are Referral Earnings and MintBox Lucky Digit the same thing?** No. Referral Earnings is a long-term referral share tied to secondary-market trading revenue from your invitees. MintBox Lucky Digit only applies within a specific MintBox and is used to improve your Tickets' odds of winning in that MintBox. --- # 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.
