How to swap arbitrum one?

How do I go about swapping Arbitrum One tokens? Is there a specific platform or process I need to follow? Can I do it directly through my crypto wallet, or do I need to use an exchange? Are there any fees involved in the process, and if so, how much can I expect to pay? Additionally, is there a minimum amount of Arbitrum One that I need to have in order to swap, and how long does the process typically take?
