# Refer a friend Referral system is a way of motivating users for attracting new participants to the project. When a user registers in the application using a referral link and creates a wallet, the one who invited him receives 20% of this user's income. In this case, the income of the invited user is not reduced, and this 20% becomes additional income for the one who invited him. In addition, if the invited user invites someone else, the user who invited them will receive an additional 5% of their income. This 5% is also not deducted from the income, but becomes additional income. The income received by the invited user is credited to a special referral warehouse. This warehouse has a capacity limit, which can be increased for tokens. To get tokens from the warehouse, you need to go through a process similar to that of a single miner's warehouse. If the warehouse is full, tokens from referrals will not be credited. --- # 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.
