活动简介
Automated Market Makers (AMMs) are a popular type of decentralized exchanges, in which users trade tokens with each other directly and automatically through a liquidity pool and a fixed pricing function. Liquidity providers (LPs) can contribute to the liquidity pool by supplying tokens to the pool and earn transaction fees in return from users who trade through the pool. We propose a model of optimal liquidity provision in which a risk-averse LP decides the number of tokens to supply to the pool and trade in an open market, and the consumption amount in multiple periods. We derive the LP’s optimal strategy by dynamic programming and study the impact of the transaction fees and pricing function on the number of tokens supplied by the LP. This is a joint work with Xuedong He and Yutian Zhou.
