We present a novel framework to estimate the implied fee amounts earned for a single liquidity position in liquidity pools. By calibrating the price model to options market data, we derive a volatility surface that enables accurate pricing of AMM positions. This allows us to quantify the expected profitability of market-making in liquidity pools, bridging the gap between traditional options pricing and decentralized finance, providing a robust tool for evaluating and managing positions in liquidity pools. This is a joint work with Diogo Duarte and Lucas Xisto.
