Can you swap XLM?

Excuse me, could you please clarify for me if it's possible to swap Stellar Lumens (XLM) in your platform or service? I'm interested in knowing if there are any restrictions or requirements for performing such an exchange, and if so, what they might be. Additionally, I'd appreciate it if you could provide some insight into the process and any associated fees that might apply. Thank you for your time and assistance with this matter.
