Some people did not quite understand, so this needs explanation. Concentrated liquidity in ranges (like Uniswap3 and others doing that) tend to have liquidity from price A to price B. And this range of prices for stable pairs is VERY tight. Asset sometimes like to go out of that range. And if there is no one else providing liquidity out of range - REKT (asset depegs or experiences extreme volatility). This is where ol good stableswap saves the show! It has concentrated liquidity, but it doesn't stop anywhere. Some liquidity is present at any price. So stableswap is the pioneer of concentrated liquidity, but it is also the endgame AMM algorithm for pegged assets, even after so many years!
