This guide is written for individuals looking to buy and sell ("swap", "exchange", "trade") cryptocurrency on OpenDEX.
There are two ways to go about it:
Use an OpenDEX-enabled exchange. The recommended and by far the easiest way to get the job done. Benefit from an easy-to-use website, no-account and no-KYC policy and trade directly from your (mobile) wallet, always in full control over your assets. Lightning supported.
xud to trade on OpenDEX directly. Not trivial to set up and operate, but offers the full feature set of OpenDEX (e.g. instant settlement).
If you decided for #2, running xud directly, follow this guide for market makers. It explains how to use
xud-docker, the recommended way to set up a full
xud trading environment. You can skip all market-maker specific steps, like connecting to an external exchange and don't necessarily need a separate box if you want to just trade occasionally.
