# Dual-Liquidity Pairs

Each Codex LP can have its own type, depending on the expected price correlation level between the two tokens of the pair.

### Volatile pairs <a href="#volatile-pairs" id="volatile-pairs"></a>

Volatile pairs are traditional Uniswap V2 pairs that are using the standard constant product formula:

$$
x \* y = k
$$

### Stable pairs <a href="#stable-pairs" id="stable-pairs"></a>

We’ve adopted the Solidly stableswap algorithm whose innovative price curve formula supports swaps of pegged assets with minimum slippage:

$$
x^3 \* y + y^3 \* x = k
$$
