# Referral Codes This will help to expand the player base and provide players with additional passive income. After the first Battle Royale season, the referral code system will be implemented. A player must own a Skin or Project NFT in order to use referral codes. Owners of Skin NFTs will be the first to be able to to refer other players with their code. * Owners of referral codes will receive 5% of the rewards found by other players. * Taxes will be discounted by a particular %, depending on NFT Guild, for those who utilise referral codes. --- # 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.
