Can I use Uniswap in the USA?

I'm a bit puzzled about the legalities surrounding cryptocurrency exchanges in the United States. I've heard of Uniswap, a popular decentralized exchange, and I'm interested in using it for my crypto transactions. But before I dive in, I'd like to make sure it's legal to do so in the US. Is Uniswap available and legal to use in the United States? I've read conflicting information online and I'm not sure which sources to trust. Could you clarify this for me? I'd appreciate any insights you can provide on this matter.
