# Constant Product Pools

Constant Product (CP) pools were the first liquidity pool type to debut and utilize the now-classic formula **x \* y = k**, where *x* and *y* are the assets in a given pool and *k* is the constant. This means these pools must enforce a 50/50 equal weighting between the two assets in the pool. When providing liquidity, LPs will be forced to add equal amount of both assets so that k remains constant, always.
