Where can I buy wrapped BTC?

Could you please tell me where I might be able to purchase wrapped BTC? I've been hearing a lot about it lately and am interested in adding it to my portfolio. I'm not sure which exchanges offer it, or if there are any specific platforms that you would recommend. Also, I'm wondering if there are any particular considerations I should take into account when purchasing wrapped BTC, such as fees or transaction times. Could you provide some guidance on this? Thank you in advance for your help.
