Curve is an exchange liquidity pool on Ethereum (such as Uniswap), which aims to provide extremely efficient stable currency transactions, low risk, and provide supplementary fee income for liquidity providers without opportunity cost. Curve allows users (and smart contracts such as 1inch, Paraswap, Totle, and Dex.ag) to trade between DAI and USDC and earn fees through a custom low-slippage, low-fee algorithm designed specifically for stablecoins. Behind the scenes, liquidity pools are also provided to the Compound protocol or iearn.finance, where more income is generated for liquidity providers. SCURVE is the Curve sUSD pool token.
