Uniswap vs. Curve 做市曲线分析

此文从无常损失和滑点两个方面,分析 Uniswap 和 Curve (主流自动做市商) 稳定币做市曲线。定义滑点有2种定义。本文采用第一种定义方法,反映交易者成交的真实平均损失。(成交平均价格-初始价格)/ 初始价格(成交后价格-初始价格)/ 初始价格无常损失定义:有两种选项参加流动性挖矿 ==> w10(参与挖矿的资产市值)持有资产,不参加流动性挖矿 ==> W11(不参与挖矿的资产市值)无常损失 = (w10 - w11) / w11结论 -- 稳定币对交易选择什么样的做市曲线,这是一个滑点(交易者)和无常损失(流动性提供者)的权衡利弊。就稳定币而言,我们追求更低的滑点,且绝大多数情况下价格会在1附近波动。Uniswap v3 和 Curve 曲线会是更好的选择,因为他们相当于加个杠杆的uniswap v1/v2 曲线,同样的成交量可以带来更低的滑点。而Uniswap v3 和 Curve 曲线可以通过调整参数(价格区间和A值)达到相似的效果。就现在市场而言(P=[0.9986, 1.0014], A=5000),Curve 能够在价格在1附近提供更好的滑点,而无常损失和Un...
