The Exchange Union Daemon (
xud) is the reference implementation powering OpenDEX, a decentralized exchange built on top of the Lightning and Raiden network.
xud brings individual traders, market makers and exchanges onto OpenDEX to form a single global trading network and liquidity pool.
Traders use OpenDEX-enabled exchanges as gateways to trade on OpenDEX. These exchanges are hosted on a server by an exchange operator. Under the hood, these exchanges interact with the OpenDEX network and abstract all the complexity that comes with it into a nice user interface for end-users. Exchanges use
xud to hedge user trades using the liquidity on OpenDEX. Market Makers use
xud to offer liquidity on OpenDEX with a premium leveraging arbitrage to external exchanges, like Binance. Exchange Union provides tools that help decrease the friction for both sides of the marketplace. Exchanges can use the
hedgy-tool to automate the hedging with
xud and market makers can use
arby, another tool that helps them leverage arbitrage opportunities between OpenDEX and external exchanges.
