# Start for free

If you're using Cryptum to develop a Proof of Concept, a hypothesis test, or simply an 'unofficial' MVP, chances are you've created a **Free project**, right?

To do so, access our **Dashboard** and **create your first Community Edition project**, as shown in the following image:

{% hint style="info" %}
Note that you can create a **free** project in **testnet** or **mainnet.** You can create both - and they will exist in the dashboard, but in a separate view.
{% endhint %}

To officially go to market with your web3 product using the blockchain **mainnets**, you should target your development towards the **mainnets** of the blockchain networks.

**Your new Mainnet API Key will give you access to all major blockchain production networks.** However, you will have **limited use** until your monthly credits run out. Keep an eye on the credits counter in your project!

If you want to create a custom project using mainnets you will have to **contact our sales team so that we can create a customized plan for your business** - amount of credits, performance and technical and business guidelines!&#x20;

{% hint style="danger" %}
It is important that you pay attention when deploying your product to production - for that, you will have to change the parameters in the implementation, using your API Key from mainnet and not from testnet.&#x20;

Also remember to change the parameters in the codes, where testnets were called before.
