innovative AMM with high Capital Efficiency and simple UX

BrownFi AMM Introduction

A novel AMM protocol with high Capital Efficiency (aka liquidity concentration) & tailored market making strategies, while keeping a simple UX, fungibility, and reusability of LP tokens from Uniswap v2. Our simulation shows that BrownFi AMM offers capital efficiency 100X higher than UniswapV2.
