Yield Basis, developed by Curve Finance founder Michael Egorov, is an AMM-based DeFi protocol designed to eliminate impermanent loss for liquidity providers. It uses 2× leverage via crvUSD to optimize liquidity positions, potentially increasing yields for BTC and ETH holders while maintaining sustainability. Liquidity positions are tokenized into yield-bearing assets like ybBTC and ybETH, enabling staking for additional rewards.
