Strategic Liquidity Provision in Uniswap v3
share
Uniswap is the largest decentralized exchange for digital currencies. The newest version, called Uniswap v3, allows liquidity providers to allocate liquidity to one or more closed intervals of the price of an asset, instead of over the total range of prices. While the price of the asset remains in that interval, the liquidity provider earns rewards proportionally to the amount of liquidity allocated. This induces the problem of strategic liquidity provision: smaller intervals result in higher concentration of liquidity and correspondingly larger rewards when the price remains in the interval, but with higher risk. We formalize this problem and study three classes of strategies for liquidity providers: uniform, proportional, and optimal (via a constrained optimization problem). We present experimental results based on the historical price data of Ethereum, which show that simple liquidity provision strategies can yield near-optimal utility and earn over 200x more than Uniswap v2 liquidity provision.
