The Classic StableSwap is an implementation of Curve Finance’s AMM on PancakeSwap. It adds linear invariant constant sum curve (x+y=k) on top of the constant product formula (x*y=k) to keep prices more equal as long as the liquidity pool is not extremely unbalanced. As a result, since StableSwaps are restricted to similarly priced assets, impermanent loss is not as much of a concern (except in extreme depeg cases) and the slippage is lower than normal AMM which just uses the constant product formula.
When you conduct a Swap (trade) on the StableSwap you will pay lower trading fees, than the usual 0.25% on normal PancakeSwap AMM. The fee attribution is broken down as follows:
50% to the LP as rewards
40% to CAKE buyback and burn
10% to the PancakeSwap Treasury
