Trading of ATS with sufficient liquidity is essential for the success of a project and ARTIS 2.0 follows a step-wise approach.
The listing on Decentralized Exchanges (DEX) as well as on Centralized Exchanges (CEX) helps to build up enough liquidity to trade ATS without much slippage.
The xDai Chain the home of the Honeyswap DEX and it is a clone of Uniswap. Therefore it has the same advantages and disadvantages as Uniswap, but benefits from the low transaction fees on xDai Chain. Creating pools, adding or withdrawing liquidity or simple swapping are almost free. The liquidity on this DEX is on the rise and the 1Hive community, which developed Honeyswap, is very active in the space, preparing several financial protocols - e.g. a borrowing/lending protocol called Agave which is a Aave fork.
At the time of writing, it is hard to tell which of the protocols is the best for ATS to get a listing and it will be up to the ARTIS DAO to decide which ones should be supported.
Being listed on a CEX helps all beginners as well as established traders to access the ARTIS ecosystem and even the first CEX listing should be on a well positioned one, with high reliability and security.
A listing on a top CEX broadens the access for traders to access the ARTIS ecosystem and therefore it is paramount to be listed on one of the top tear exchanges.
This listing of ATS will put ARTIS on par with the EWT and MIOTA.
