Looks like TrustCo Bank is the best fit, since "trustco" matches a financial-services style brand and a .pay registration strongly points to payments or banking use. Still, it could also be another trademark holder using the same name.

Frequently asked questions about bigfish.pay
Can I transfer a .PAY LRP domain to someone else?
A .PAY name registered during an LRP may be transferred only to a new registrant that fulfills the same LRP eligibility criteria. For registration or pre-order assistance, start at domain.pay: https://domain.pay/register. Do not buy or sell LRP names without confirming eligibility.
How does sunrise work for bigfish.pay?
Sunrise is the first launch phase, open only to brand owners with a trademark validated through the Trademark Clearinghouse (TMCH) and an SMD file. If you hold a matching mark, domain.pay can submit bigfish.pay during sunrise on your behalf. Learn about trademark-priority registration at https://domain.pay/register.
How is a .PAY name different from a regular .com for loan repayments?
A .PAY name immediately signals a payment-related destination, while .com is more general. For loan repayments, that can make the URL easier to understand. Check availability and pre-order options at domain.pay: https://domain.pay/. The usual registry and premium-name rules still apply.
Is bigfish.pay a good fit for a payments brand?
A .PAY name like bigfish.pay signals a payments, fintech, or checkout focus directly in the address, which can make bigfish memorable for that use. .PAY is run by Amazon Registry Services as a namespace oriented around payment services. Reserve bigfish.pay at https://domain.pay/register.
Why are payment brands talking about .PAY as a startup for crypto payments?
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/.
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.
