# User Levels

![User levels, divided into five groups](https://1892045298-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZImlOLJrv8EMkRcnb01Q%2Fuploads%2FwOFH5TYW9SIbo79cWo0T%2Fimage.png?alt=media\&token=dc848464-9599-428b-870c-233a87c0edf1)

Users can upgrade up to level 30. At the highest level, users need to choose between earning SDD or XDD. Switching between SDD/XDD earning is allowed but is subject to a cooldown.

At level 30, users can burn SDD/XDD/NFT to customize their AI watch, including but not limited to - changing the name, adding quotes, adding additional attribute points, etc. We will release more details on customization, it will be online soon.
