Balancer-style and concentrated liquidity
Weighted pools distribute liquidity across their full curve, while concentrated-liquidity positions select a price range and can become one-sided when the market moves outside it. A swap can route across several pools. The user pays pool fees and experiences spread or price impact in addition to the chain transaction fee.
Review the exact route, minimum received, pool fee and price impact before signing. Liquidity providers should inspect range, token weights, incentives and impermanent-loss exposure. A high displayed APR can combine temporary emissions and fees and does not state the loss from a changing asset ratio.
