Impermanent Loss is the scourge of liquidity providers and must be dealt with to make decentralized finance a sustainable solution.

The Concentration-Asymmetric Liquidity Model (CALM) is designed to make providing liquidity sustainably profitable. 

The main innovation is that CALM treats trades that increase impermanent loss differently from those that reduce it, thereby reducing the negative impact of impermanent loss. 

The result is an algorithm that is efficient to implement, and (most importantly) vastly outperforms traditional methods in terms of bottom-line performance for liquidity providers.
