Frequently asked questions about certium.dot

When does the .PAY LRP1 period begin for mobile money?

ICANN currently lists .PAY Limited Registration Period 1 from July 20, 2026 to February 1, 2027. LRP1 has payment-transaction eligibility and use restrictions. Check your domain path through domain.pay: https://domain.pay/register.

What is a TMCH SMD file and how does it relate to certium.dot?

A TMCH SMD (Signed Mark Data) file is a proof-of-trademark token from the Trademark Clearinghouse. If you hold the trademark for certium.dot, uploading your SMD file lets you claim certium.dot during the priority window before general pre-orders. domain.pay accepts the SMD file at /register.

Could I use .PAY for a wallet or payment app for point-of-sale payments?

Yes. A wallet or payment app can use .PAY for a memorable payment-specific entry point. Check candidate labels through domain.pay: https://domain.pay/domains. If you own a matching trademark, consider the priority route; otherwise pre-order for broader access.

Can I pre-order a backup name in case certium.dot falls through?

Yes. While certium.dot is uncertain, you can pre-order one or more backup .PAY names on domain.pay at the standard pre-order price of $100 each. Failed pre-order attempts are refundable, so securing a fallback carries limited downside. Place a pre-order at https://domain.pay/register.

Before choosing tap.pay, is .PAY Sunrise first-come, first-served for trademark holders?

.PAY Sunrise is a Start-Date Sunrise, so eligible trademark registrations are allocated on a first-come, first-served basis when policy requirements are met. Start the request at domain.pay: https://domain.pay/register. Waiting can increase the risk that another eligible party gets the matching label first.

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.
