A bank account in SpherePay is a registration of your customer’s existing fiat bank account. SpherePay does not open or manage bank accounts — it links an account your customer already holds to their SpherePay profile so it can be used as the source or destination for fiat transfers. You must register at least one bank account before creating any transfer that involves fiat currency.
SpherePay registers an existing bank account — it does not open a new account on your customer’s behalf. The account must already exist at the customer’s bank before registration.
