Private purchase usually means reducing unnecessary traditional registration data, but the domain registration itself still follows extension and registrar rules. Some extensions need only basic contact information; others may request additional details. The exact requirement depends on the domain and registration flow.
Do not compare only the price. Check the term, renewal, privacy options, DNS access, transfer limits, and recovery method. USDT-TRC20 defines the payment path, while the anonymous account preserves order access; neither replaces a registrar’s required fields.
The practical approach is to check first, review the order requirements, and pay only after you know how the domain will be controlled over time.
