Block-0 appears in **Launch Settings** only when the current network, launchpad, variant, and quote asset support it.

Choose a preset to calculate wallet layers and delays from your holder count, or Custom to set them yourself.

1.  ## Choose a build
    
    Select **Block-0**, then set the developer buy or supply, holder buy, and holder count shown for the launch.

    | Preset | Layers and timing |
    | --- | --- |
    | **Quick Build** | **Lower cost · simpler** Front and Back; shorter holder-buy delay and lower complexity. |
    | **Clean Build** | **Variable cost · longer delays** Front and Back; longer holder-buy delay than Quick. |
    | **Full Build** | **Higher cost · more complex** Adds temporary holders; the same longer holder-buy delay as Clean, with more funded wallets. |
    
    **Four.meme**
    
    | Preset | Layers and timing |
    | --- | --- |
    | **Quick Build** | **Lower cost · simpler** MEV wallets distribute directly to holders; shorter holder-buy delay. |
    | **Full Build** | **Higher cost · more complex** Adds a temporary layer and a longer holder-buy delay. |
    
    **Pons**
    
    | Preset | Layers and timing |
    | --- | --- |
    | **Quick Build** | **Lower cost · simpler** MEV wallets distribute directly to holders, with no configured interval between holder buys. |
    | **Full Build** | **Higher cost · more complex** Adds a temporary layer; no configured interval between temporary-wallet buys, then a longer interval between holder buys. |
    
    Costs and execution limits
    
    Compare costs for the same route and holder count. The funding estimate gives the amount required for your configuration.
    
    Full Build adds funded wallets and operations, increasing the funding requirement. On Pons, delays apply per recipient, not to an entire phase. A preset does not guarantee elapsed time, transaction inclusion, or that wallet links remain undetected.
    
2.  ## Customize the setup (optional)
    
    Choose **Custom** to edit the fields supported by your route. Follow the displayed limits and time units.
    
    Solana · Custom · example layers
    
    1.  **Front MEV** First wallets targeting the deployment block. Front MEV Count
    2.  **Back MEV** Optional Optional buyback layer after Front MEV. Back MEV Count
    3.  **Temp Holders** Optional Optional intermediate layer before the final holders. Temp Holder Count
    4.  **Holders** Final wallets receiving the allocation. Holders Count
    
    Front→Back Delay
    
    Delay between the Front and Back MEV layers.
    
    Back→Temp Delay / MEV→Temp Delay
    
    Delay from the last MEV layer to temporary holders.
    
    Buy Delay
    
    Interval between final holder buys.
    
    Example with Back MEV and temporary holders enabled. Other routes may use fewer layers.
    
    ### Back MEV Tuning
    
    On supported Solana presets, adjust **Back MEV Tuning** to change the calculated wallet count within preset limits.

    Fewer sniper-sell markers ↔ less top-trader visibility. Illustration, not a guarantee.

    **Bubble Maps**
    
    A configuration-based estimate using Buy Delay, not a scan of actual wallet links.
    
    **Supply Cost**
    
    Estimated holder supply lost during Cleanup, not the total funding amount.
    
    **Detection Mode**
    
    The visibility tradeoff associated with the tuning slider, when shown.
    
    **Cleanup Time**
    
    Estimated duration of Cleanup across the configured layers.

    > These indicators help compare configurations; they do not guarantee detection avoidance, cost or completion time.
    
    Open [Advanced Settings](https://proxima-docs.pages.dev/create-launch/launch-settings/#launch-advanced-settings) only when you need a supported option such as Slippage, Funding Delay, Fee Target, Empty Holders, or Scheduled Mode.
    
    Check estimated market cap and funding. **Create** builds the wallet layers and opens Funding.
