Frequently asked questions about sigma.dot

What is TMCH and why does it matter for .PAY for mobile money?

TMCH is the Trademark Clearinghouse. For .PAY priority registration, the trademark record must be validated and the registrant needs a matching SMD file. domain.pay can help start the fast-track or submission path: https://domain.pay/register. Begin early because TMCH handling takes time.

Can I register sigma.dot and a matching .com together?

Yes, many brands hold both sigma.dot and the matching .com, using one as the primary site and 301-redirecting the other to it. This protects the brand and captures direct-type traffic on both. You can secure sigma.dot now at https://domain.pay/register.

What is a .PAY domain and why does it matter for crypto payments for a brand-protection manager?

For crypto payments, .PAY can be a strong payment-specific brand signal. It does not replace compliance, security or a trusted checkout flow, but it can make the URL purpose obvious. Start with an availability check on domain.pay: https://domain.pay/.

How early should I pre-order sigma.dot?

The earlier you pre-order sigma.dot, the sooner your request is queued, which can matter for sought-after payment labels. There is no penalty for pre-ordering well ahead of the phase opening. Lock in your queue spot at https://domain.pay/register.

What if my trademark has spaces or special characters and I want .PAY when choosing link.pay?

.PAY Sunrise follows identical-match rules for the trademark text, including how spaces and some special characters are handled. Do not guess the label; check it through domain.pay and use the trademark path if eligible: https://domain.pay/register. A valid TMCH/SMD record may be required.

Availability is checked live and re-verified before payment. Pre-orders are first-day registration attempts — registration is not guaranteed; 100% credit toward another domain (or 80% cash refund) if unsuccessful.
