# Add Arbitrum Network

For low costs, and efficient transactions, Autonomi utilises the **Arbitrum** blockchain.

So in order to be able to see and transact with Autonomi Network Tokens, you'll need to add the Arbitrum One network to your wallet.

Here's an example of how to do that using MetaMask

## Adding Arbitrum to MetaMask

{% stepper %}
{% step %}
At the top left, **click where it says Ethereum Mainnet**
{% endstep %}

{% step %}
Now you should get a pop up and should **click + Add network**

{% endstep %}

{% step %}
From the list of networks, click **Add** next to **Arbitrum One**
{% endstep %}

{% step %}
Now click **Switch to Arbitrum One**
{% endstep %}
{% endstepper %}

Next you'll need to [**import the token contract**](/token/using-autonomi-tokens/holding/import-the-autonomi-token.md) so you can see your Autonomi Network Tokens in your wallet…
