Curve is an exchange liquidity pool on Ethereum (similar to Uniswap), designed for extremely efficient stablecoin trading, with low risk, and providing supplemental fee income for liquidity providers without opportunity costs. Curve allows users (and smart contracts like 1inch, Paraswap, Totle, and Dex.ag) to trade between DAI and USDC using a custom-designed low slippage, low-fee algorithm specifically tailored for stablecoins, earning trading fees in the process. Behind the scenes, the liquidity pools also contribute to the Compound protocol or iearn.finance, generating additional income for liquidity providers. RENBTCCURVE is the Curve PAX pool token.
