Although stable swaps seem like a simple enough concept, they're actually quite complex under the hood. Although complex, their efficiency has made stable swaps one of the most important tools in decentralized finance (DeFi) today.

Stableswap pools are the middle ground between constant product pools and constant price pools. A constant price pool is similar to a constant product pool, but uses a constant sum formula

**+***Rx***=***Ry***k**, resulting in a constant price**∆x**/**∆y**= 1.The stableswap invariant algorithm uses an amplification parameter

**A**that determines how close the stableswap curve should be to the constant product curve; an amplification value of 0 (*A = 0*) achieves results identical to the constant product pool algorithm; higher values of*A*push the curve closer to the constant price curve, resulting in lower slippage for exchange rates close to 1:1.The formula for the stableswap invariant works by combining terms representing the constant product and constant sum formulas. It's using the constant

**D**to represent the total number of tokens in the pool when token X and token Y have an equal price, and**A**represents the amplification parameter. The formula can be written as:- Sustained and stable fee income.
