# Tier System

Your tier determines how many people can use your referral code simultaneously.

## Tiers

| Tier | Name    | Referral Slots | Required Own Volume |
| ---- | ------- | -------------- | ------------------- |
| 0    | Starter | 5 slots        | $0 — default        |
| 1    | Active  | 10 slots       | $200,000            |
| 2    | Pro     | 20 slots       | $5,000,000          |
| 3    | Elite   | 30 slots       | $50,000,000         |

Volume = your **own** cumulative trading volume on Zest (not your referrals' volume).

## How slots work

Each slot = one person who can redeem your code. When all slots are filled:

* Existing referrals remain connected
* New users can't redeem your code
* Trade more volume → upgrade tier → more slots open

## Upgrade example

You're at Tier 0 (5 slots, all full). You trade $200K total volume → automatically upgrade to Tier 1 (10 slots, 5 new slots available immediately).

## Special case: Referred users

If someone invited you with a referral link:

* Your code starts **locked** (0 slots)
* Trade $200K → code unlocks **and** you jump directly to **Tier 1** (10 slots)
* You skip Tier 0 entirely as a bonus for being an active trader

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zest.ac/referral-program/tiers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
