# Block-0 Configuration

### How It Works

In Block-0 Mode, supply passes through multiple execution layers before reaching the final holders. Each transition is a coordinated buy and sell in the same block: one layer sells while the next buys the same amount simultaneously.

#### Front MEV

First layer. Buys supply in the deployment block before any external transaction.

#### Back MEV

Second layer. Buys as Front MEV sells in the same block. The number of Back MEV wallets affects how the distribution appears on third-party analysis tools.

#### Temporary Holders

Third layer. Buys as Back MEV sells. Adds an additional execution step before final allocation.

#### Holders

Final layer. Buys as Temporary Holders sell. Holds supply according to your launch plan.

{% hint style="info" %}
No tokens are transferred between wallets. Each step is an independent buy/sell pair executed in the same block.

### Block-0 Presets (Block-0 only)&#x20;

Presets define how many wallets are used in each layer and the timing between them. By default, only the preset selector is visible. Custom mode reveals all parameters.

#### Quick Build

Fast, compact distribution with efficient early cleanup. Low complexity and cost.

* Fewer layers
* Shorter delays
* Lowest funding requirement

#### Clean Build

Balanced distribution focused on long-term structure. Moderate complexity and cost.

* More layers than Quick Build
* Longer delays between steps
* Better indicator scores

#### Full Build

Maximum distribution layers. Highest cost, longest cleanup time.

* Maximum Front and Back MEV wallets
* Longest delays
* Best indicator scores

#### Custom

Full manual control over all parameters. For advanced users who want to fine-tune every step.

Selecting Custom reveals the following inputs:

* **Front MEV Count** (1-12): Number of front MEV wallets
* **Back MEV Count** (0-100): Number of back MEV wallets
* **Temp Holder Count** (0-200): Number of temporary holder wallets
* **Front→Back Delay** (0-10000ms): Delay between front and back MEV execution
* **Back→Temp Delay** (0-10000ms): Delay between back MEV and temporary holders
* **Buy Delay** (0-60000ms): Delay before final holder execution

### Back MEV Tuning

Available on all presets. Controls the tradeoff between two outcomes:

<div align="left"><figure><img src="/files/FJ9qNaNNqBlKWxTScjN5" alt="" width="563"><figcaption></figcaption></figure></div>

* **Left** : Less "Sniper Sold" markers on charts
* **Right** : Less likely to appear as top trader on analysis tools

This slider adjusts the number and behavior of Back MEV wallets. There is no optimal setting. Adjust based on what you want to prioritize.

### Indicators

The right panel displays four real-time indicators that update based on your MEV configuration.

#### Bubble Maps

Scale: Uncertain → Likely clean

Estimates how the distribution structure will appear on BubbleMaps. More layers and longer delays improve this score.

#### Supply Cost

Scale: Low → High

Shows the relative cost of the selected configuration. More layers and wallets increase cost.

#### Detection Mode

Scale: Less Sniper → Less Top Traders

Indicates the tradeoff between reducing sniper visibility and reducing top trader visibility on third-party tools. Directly linked to the Back MEV Tuning slider.

#### Cleanup Time

Scale: Fastest → Longest

Estimated time for the full distribution to complete across all layers. More layers and longer delays increase cleanup time.

{% hint style="info" %}
Indicators are estimations based on your configuration. Results may vary depending on external market conditions.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.proxima.tools/create-launch/launch-settings/block-0-configuration.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.
