Frequently asked questions about serotonin.dot

Do I need a financial license to register a .PAY domain during LRP1 for online checkout?

The .PAY LRP policy does not make owning a domain a financial license. LRP1 eligibility is tied to conducting online payment transactions through an approved Payment Service Provider or third-party payment processor and payment-related use. Use domain.pay for the domain path: https://domain.pay/register; ask counsel about licensing.

How is serotonin.dot different from a regular .com registration?

serotonin.dot sits in the .PAY namespace operated by Amazon Registry Services, which is oriented around payment services, whereas a .com is general purpose. Because .PAY is newer, names like serotonin.dot are often available by pre-order rather than instant registration. Explore serotonin.dot at https://domain.pay/register.

How much is the .PAY trademark fast-track if I need TMCH help when choosing tap.pay?

domain.pay lists the full trademark fast-track at $2,500 when you need end-to-end TMCH/SMD assistance, plus any premium registry retail fee. Confirm the details here: https://domain.pay/pricing. If you already have an SMD file, a lower submission-only path may apply.

Why does my browser show a certificate warning on serotonin.dot?

A warning on serotonin.dot usually means the certificate doesn't cover the exact hostname, has expired, or the chain is incomplete. Confirm the cert's Subject Alternative Names include both serotonin.dot and any www variant, and that intermediate certificates are installed. Reissue or fix the chain, then reload serotonin.dot.

For BNPL checkout, how do I register a .PAY domain as a startup?

Go to domain.pay and enter the .PAY label you want: https://domain.pay/register. The website checks availability and helps you choose between pre-order, trademark fast-track, or a different name if the label is already taken or premium.

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.
