What country is Uniswap based?

I'm curious about Uniswap's geographical roots. Could you please elaborate on the country where Uniswap is primarily based? It seems to be a significant player in the decentralized finance space, and I'm interested in understanding its geographical context. Is it headquartered in a particular country that fosters a favorable environment for blockchain innovation? Or does it operate more globally, without a specific national base? Your insights would be greatly appreciated.
