Parallel offers two distinct types of Automatic Market Makers to provide a wider range of possibilities to its users. More specifically, "Stable" is a low slippage AMM suitable for stable 1:1 ratio assets while "Dynamic" is a general-purpose AMM for any kind of asset combination with a higher slippage.
To have a better understating on each type of AMM, take a look at the sub-categories of this chapter.
The nomenclature chose for internal swaps is the old buy and sell operations used on the Stock market, Forex market, crypto CEXs or any other order-book based entity.
Given a [X, Y] asset pair, buying X (base) means swapping Y (quote) for X (base) while the opposite (selling) means swapping X (base) for Y (quote). Therefore, for any [X, Y] asset pair, base is X and quote is Y.
All with that said, accounts buy or sell base assets and pay or charge quote assets.
