Impermanent Loss (IL) is the unrealized loss that automated market makers (AMMs) suffer when assets they hold diverge in price from their initial deposit ratio. When you deposit equal-value pairs into a liquidity pool and prices shift, the AMM algorithm forces you to hold more of the cheaper asset and less of the expensive one—rebalancing you into a losing position. Hedging IL means offsetting this risk through stablecoins, derivatives, range orders, or algorithm design. The goal is to capture trading fees without suffering the rebalancing drag.
