Is it legal to use Uniswap in the USA?

I'm curious about the legality of using Uniswap in the United States. As a decentralized exchange for cryptocurrency trading, I understand that it operates outside of traditional financial regulations. However, I'm wondering if there are any specific laws or regulations in the US that prohibit or restrict the use of Uniswap. Additionally, I'd like to know if there have been any cases where individuals or businesses have faced legal consequences for using Uniswap in the US. Could you provide some clarity on this topic?
