There are a bunch of other sites for swaps but Uniswap is probably the one which is getting the most attention. There is also Sushiswap. I dont understand their obsession with rainbows or unicorns because I am old school user and prefer a clean and easy interface and less such gawdy stuff. Still you can trust any of them that you wish to you and allow it to exchange your etherum tokens. Probably more features will be added in soon like which I want is direct conversion to BTC.

Just be careful that you are visiting the official site when linking your wallet and not a phishing site. Bookmark it to be safe. Dont use links to visit it.
