Uniswap allows users to provide liquidity for specific markets, earn fees in return for providing liquidity, and trade any token pair instantly while offering yield farming options that can help generate passive investment returns. Furthermore, it has built-in safeguards such as price slippage limits and rate-limiting, which protect traders from exploitation or manipulation of prices.
