The network effect for liquidity.

We at Exchange Union are building xud, the software for a decentralized exchange network called OpenDEX. It brings market makers, exchanges and individual traders worldwide onto a single trading network and liquidity pool. OpenDEX solves the major pain point of most exchanges: the lack of organic liquidity. Some OTC-style exchanges already run XUD with a set of tools to use the network's liquidity for hedge-trading their user trades and control exposure of different assets, essentially using OpenDEX's liquidity to offer trades to their users. Examples of such exchanges can be found here.

Benefits for exchanges and their users.


  • Open and free access to a global liquidity pool
  • No more paying market makers
  • No more paying remarketing services
  • Compete with UX instead of liquidity
  • Increased user stickiness


  • Better UX
  • More pairs
  • Access to the best global price
  • No KYC, no personal data
XUC, the liquidity incentive.

XUC is a token which incentivizes market makers to provide liquidity on the OpenDEX network. It has been designed to reward the work that is needed to "transfer" liquidity from major exchanges onto OpenDEX. Select the Market Maker journey to learn more about how it works. An open market place like OpenDEX has its drawbacks though, namely it is vulnerable to the so-called free options problem where actors delay trades to exploit rate changes. Exchanges will be able to use XUC to gain access to a curated list of regularly tested and reliable market makers to ensure trades always execute successfully and instantly.
