Uniswap and Curve are both decentralized exchanges (DEXs) that allow users to trade cryptocurrency tokens. The main difference between the two is the type of tokens they support. Uniswap is an automated market maker (AMM) protocol that supports ERC-20 tokens, while Curve is a liquidity pool protocol that supports both ERC-20 and ERC-721 tokens. Uniswap also supports a wide variety of trading pairs and allows users to create their own trading pairs, while Curve has a limited number of trading pairs. Additionally, Curve offers a variety of yield-generating mechanisms, such as staking and flash loans, which Uniswap does not support. Ultimately, the choice of which DEX to use depends on the type of tokens you want to trade and the yield-generating mechanisms you are interested in.
