Does my trademark have to exactly match the label in castellum.dot?

For trademark priority, the validated mark in your SMD must correspond to the castellum.dot string in castellum.dot under TMCH matching rules. Close-but-different strings generally do not qualify for priority on castellum.dot. If the match is exact, your SMD unlocks the priority claim. Check your eligibility and register at https://domain.pay/register.

Can a trademark holder challenge a bad .PAY Sunrise registration for donation payments?

.PAY Sunrise registrations can be subject to Sunrise dispute procedures if the registration or denial violates the Sunrise criteria. Start by checking your own label at domain.pay: https://domain.pay/register, and coordinate with trademark counsel for formal dispute strategy.

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.
