# Using Zenlink DEX

In order to optimize the Zenlink DEX architecture and user experience, we have launched a revamped new APP, while the old APP will be kept at the same time at the initial stage (the old APP is expected to be taken offline a few months after the new APP), the new APP and the old APP use separate web page (URL), please pay attention to distinguish them! 

**New APP:** <https://app.zenlink.pro/>

**Old APP:** <https://dex.zenlink.pro/>&#x20;

The UI\&UX of the new APP and the old APP is very different, so to make it easier for users to get started, please follow the different user guides:&#x20;

**New APP User Guide:** [new-app](https://wiki.zenlink.pro/zenlink-dex-dapp/user-guide/using-zenlink-dex/new-app "mention")

**Old APP User Guide:** [old-app](https://wiki.zenlink.pro/zenlink-dex-dapp/user-guide/using-zenlink-dex/old-app "mention")
