Can USA use Uniswap?

Can someone from the United States use Uniswap to trade cryptocurrencies? I understand that Uniswap is a decentralized exchange that operates on the Ethereum blockchain, but I'm not sure if there are any regulations or restrictions that prevent US citizens from using it. I'm also curious if there are any potential tax implications or other considerations that US users should be aware of when trading on Uniswap. Could you provide some clarity on these points?
