Excuse me, could you please clarify something for me? I'm interested in converting my USDT to WETH. Is it possible to make this swap? If so, could you guide me through the process? I'm a bit unfamiliar with the intricacies of cryptocurrency exchanges, so your expertise would be greatly appreciated. Could you also tell me if there are any fees involved in this swap, and what the current exchange rate is? Thank you in advance for your help.
