The BarterDEX is a fully decentralized exchange that is both convenient and reliable. Contrary to previous solutions, the BarterDEX supports atomic swaps, which means that cryptocurrencies can be exchanged directly without the need to deposit the actual coins in some form of escrow and use proxy tokens, pegged assets, or any other variation.
