Consider x and y to be the token amounts available in the liquidity pool.
A Constant Product Market Maker (CPMM) Curve is a curve that is defined by the following equation:
x * y = k
where k is called the pool invariant.
It tries to keep the product constant. If you need to exchange a number of tokens , you will receive y - k/(x+a) tokens.
However, this curve is not suited for stablecoins because the amount you get of exchanging goes down as you try to exchange more tokens.
Hence, a new curve needs to be defined that is more suited for stablecoins.
