{% hint style="info" %}
Magnet's on-demand coretime mode includes on-demand block production. If no transactions occur, block production will be halted.
{% endhint %}

**Basic Information:**&#x20;

&#x20;  \- Input the name of your chain and the ParaID you reserved.

**Native Token:**&#x20;

&#x20;  \- Define your native token or use DOT as the native token for your chain.&#x20;

&#x20;  \- If using DOT, select "DOT as GAS."

&#x20;  \- Set your token's decimal places.

**Coretime Order Control:**

Config these parameters to utilize Magnet Network’s order control mechanism for on-demand orders.

&#x20;    \- Price Limit: Sets an upper limit for coretime price. Orders will not be placed if exceeded.

&#x20;    \- Price Threshold: Controls profitability from gas collection.

$$
\text{Price Threshold} = \frac{\text{Gas Fee Collected}}{\text{Coretime Price}}
$$

{% hint style="info" %}
Price Threshold is available only when using DOT as GAS because coretime cost and revenue are measured in different tokens if using a native token.
{% endhint %}

&#x20;  \- Set the initial balance for the sudo account (if not using DOT as GAS).
