Utility tokens are specific types of cryptocurrencies that are created to be used solely within a particular ecosystem, allowing users to access services or tools within that ecosystem. Unlike security tokens which represent ownership or share in a company, utility tokens are used primarily to facilitate transactions and promote usage of the platform they are associated with. For example, users may need utility tokens to access certain features, make purchases, or gain privileges on a platform. They are often distributed through initial coin offerings (ICOs) or token sales, and their value is typically driven by the demand for the services or products they provide access to.
