Is PayPal USD available?

Could you please clarify whether PayPal USD is currently offered as a payment option or currency denomination within the platform? With the ever-evolving landscape of digital currencies and payment methods, it's essential to stay updated on the availability of such services. PayPal, as a globally recognized payment processor, has been a key player in facilitating transactions. However, there may be specific regions or circumstances where PayPal USD may not be readily available. Therefore, I'd like to understand if this service is currently accessible and if there are any limitations or requirements that may apply.
