{% endhint %}

Choose between "**Push**" or "**Pull**" mode.

* **Push** delivers updates proactively to the blockchain, ensuring automated data availability.
* **Pull** allows authorized addresses to fetch update on-demand during transactions, ensuring the latest data is used at the point of need.

{% endstep %}

{% step %}

### Pull Mode

{% hint style="info" %}
If you chose Push Mode skip to the next step.
{% endhint %}

For "**Pull mode**" choose the desired duration. Your subscription will remain active for the selected duration extension and will end on the expiry date unless extended beforehand by depositing additional funds, allowing you to renew it seamlessly.

You can deposit any amount, as long as it meets the minimum required. The app will automatically calculate your subscription period based on the amount you choose to deposit.

{% step %}

### Push Mode

{% hint style="info" %}
If you chose Pull Mode you can skip this step.
{% endhint %}

For "**Push mode**" select the desired deviation. This is the percentage change in value required to trigger a new update, ensuring updates are only made when meaningful updates occur.
