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
