Hi Futurewizard,
Thanks for your message.
Your name is not divulged on Sedo with any of our services. When you list your domains for sale on our marketplace and during negotiations, potential buyers looking at your domain will only see the country in which you live in. It is only if you successfully sell a domain and after the domain has been paid for by the buyer will your name and address be visible to the buyer. This is because it is necessary for the legal sales contract we provide. It is not possible to remain anonymous at this stage of selling a domain. As a seller you only see the buyer's details after the transfer completes and payment is made to you.
All the best
Chris
