Can I sell directly from gelato?

Excuse me, I'm curious about the capabilities of the platform known as "gelato" in relation to cryptocurrency transactions. Specifically, does gelato offer the functionality to directly sell cryptocurrencies from within its interface? I understand that there are various platforms designed for trading and exchanging digital assets, but I'm wondering if gelato, being a [insert specific type of platform or service if known, e.g., "dessert ordering app" or leave as is for generality], also caters to such a feature. Is there a built-in marketplace or an integration with other exchanges that would enable users to list and sell their cryptocurrencies seamlessly through gelato? Additionally, what are the fees and security measures associated with such transactions, if they are indeed supported?
