Introduction

The Exchange Union Daemon (xud) is the open-source node software powering Exchange Union, a decentralized exchange (DEX) built on the Lightning and Raiden network.

xud brings individuals and exchanges onto the same network to form a single global liquidity pool. This gives users a choice to either trade directly on the DEX by running xud, managing private keys and software stack, or to conveniently trade via a trusted exchange. Exchanges benefit from access to the network's aggregated liquidity and can provide deeper order books and new trading pairs to their users.
