# Set EcoPot

## 1. Contract Deploy

{% tabs %}
{% tab title="Deploy Guide" %}

* **The token and project name for EcoPot are set at the time of creation and cannot be modified.**
* **Please check whether the contract is deployed in the public environment**
* Please pay attention to the security of the Owner account.
* Please refer to Polygon's Smart contract deployment [here](https://docs.polygon.technology/docs/develop/getting-started)
