# VIP

SubstanceX offers a VIP grading system in order to provide users with a trading experience similar to that of CEX. The system assigns different VIP levels to users based on their perpetual trading volume over the past 30 days. Each VIP level is eligible for corresponding trading fee reductions and other services.<br>

### VIP Level Rules

### Upgrade and Downgrade Mechanism

* User levels can upgrade to higher levels without having to go through every intermediate level.

**Downgrade Mechanism:**

* Automatic downgrade. Upgrade once daily, fixed at 0:00 (UTC+0).
* Downgrades will directly adjust to the VIP level that corresponds to the current level based on data.
