About Curve PegKeeperV2

Curve implements PegKeeperV2 a more fine-grained version of PegKeeper. The goal of PegKeeperV2 is to maintain the peg of CRVUSD in its stablepools by adding or removing liquidity in the form of CRVUSD.

“Curve is an exchange liquidity pool on Ethereum (like Uniswap) designed for (1) extremely efficient stablecoin trading (2) low risk, supplemental fee income for liquidity providers, without an opportunity cost.

Curve allows users (and smart contracts like 1inchParaswapTotle and Dex.ag) to trade between DAI and USDC with a bespoke low slippage, low fee algorithm designed specifically for stablecoins and earn fees. Behind the scenes, the liquidity pool is also supplied to the Compound protocol or yearn.finance where it generates even more income for liquidity providers.”
