How does Uniswap make money?

I've been following the crypto world closely and Uniswap has piqued my interest. Could you elaborate on how Uniswap actually generates revenue? I understand it's a decentralized exchange, but surely there's a mechanism behind it earning profits. Does it rely solely on transaction fees? Or are there other innovative ways it's tapping into the financial ecosystem? I'm curious to know how this platform manages to stay afloat and continue to grow in such a competitive market.
