Fan tokens are assets that represent proof of ownership or membership. They are used for various purposes and are supported by specialized blockchains, with Ethereum and their ERC standard tokens being the most common. Socios.com is an app designed for football (soccer) fans, allowing them to acquire club-specific Fan tokens and gain voting rights to influence the clubs they support.

Fan tokens work through the use of Chiliz ($CHZ), an ERC20 utility token on the Ethereum blockchain. Chiliz serves as the digital currency for the chiliZ and Socios.com platform. The platform introduces a new category of token called Fan Token. Club partners on Socios.com host Fan Token Offering (FTO) events, where fans need to purchase $CHZ via a cryptocurrency exchange to acquire Fan Tokens. These tokens are specific to a team or club and provide access to an encrypted ledger of voting and membership rights ownership.
