Frequently asked questions about caius.dot

What happens to my money if the .PAY registration attempt fails?

domain.pay states that if a registration attempt is unsuccessful, you receive 100% credit toward another domain or may request an 80% cash refund. Review the live refund wording before ordering: https://domain.pay/pricing. Premium, reserved, blocked or already-registered names can still prevent success.

Can caius.dot power a split-bill page for groups?

Yes. A restaurant or event can host a split-the-bill page on caius.dot so each guest pays their share at a trusted address. The .PAY name makes the group settlement feel official and simple. Start at https://domain.pay/register.

For loan repayments, what does 'approved Payment Service Provider' mean for .PAY eligibility?

During LRP1, .PAY eligibility is limited to registrants that conduct payment transactions online using an approved Payment Service Provider or third-party payment processor, with payment-related use. For registration help, use domain.pay: https://domain.pay/register. Separate financial licensing depends on your activity and jurisdiction.

Why pre-order caius.dot before the sunrise window?

Pre-ordering caius.dot before the sunrise window opens means domain.pay has everything staged to submit the instant trademark-priority registration begins, leaving no gap. For brand owners this protects caius.dot early. Prepare at https://domain.pay/register.

For digital wallets, is a payment gateway business eligible for .PAY in the LRP?

An ecommerce or gateway business using a payment processor may be closer to the LRP1 eligibility concept, but the registry rules still control. Start at domain.pay to choose the correct path and verify current requirements: https://domain.pay/register. Separate licensing issues remain legal questions.

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.
