# Referral Concepts * **Invitee**: a new user who registers through your invite link and forms an exclusive invite binding with you. * **Invite Code**: the 8-digit code you can share; when others register with it, they become your Invitees. * **Bind Invite Code**: the action of entering someone else's invite code to bind yourself as their Invitee. This can be done only once and cannot be manually unbound after binding. * **Referral Earnings**: the reward you receive from secondary-market trading revenue related to your invitees (currently 10%, with the platform reserving the right to adjust). * **Total Added MintBox Allocation**: an estimate of the additional MintBox allocation value obtained through Lucky Digit boosts (estimate only). --- # 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.
