# Coin Pair

In Crescent DEX, anyone can create a pair of two coins, which is an ordered pair. The ordered coin pair is unique in Crescent DEX, which means only a single pair of a given ordered coin pair is allowed. For example, Crescent DEX can have only one pair for

`A-B`

coin pair consisting of `Coin A`

and `Coin B`

. Crescent DEX can also have `B-A`

coin pair, which is different from `A-B`

coin pair.The base coin is the first coin that appears in a coin pair quotation. Consequently, the second coin appeared in the pair is a quote coin.
