Does Kuwait accept US dollar?

Could you please clarify for me if Kuwait accepts the United States dollar as a form of currency? I'm interested in understanding the extent to which the US dollar is accepted and used in Kuwait for transactions, both by individuals and businesses. Additionally, are there any restrictions or regulations that govern the use of the US dollar in Kuwait? I'm also curious about the prevalence of other currencies, such as the Kuwaiti dinar, in the country and how they compare to the US dollar in terms of usage and acceptance.
