Exchange Union is building xud, the software for a decentralized exchange network called OpenDEX. OpenDEX brings market makers, exchanges and individual traders worldwide onto a single trading network and liquidity pool. It solves the liquidity bottleneck, which existing DEX are suffering from. Traders run XUD for fully self-sovereign trading or opt for an easy-to-use OpenDEX-enabled exchange to access the network's liqudity. Market Makers bring in liquidity from all major exchanges which does away with the need for opening and KYCing accounts on an endless number of exchanges and the constant need to move funds between them.
