# Adding Arbitrum Network

Krakatoa operates on the Arbitrum Network so you will need to add this as a supported network in your wallet. There are two ways to add the Arbitrum network:

1. Connecting your wallet [here](https://chainlist.org/chain/42161) will automatically add Arbitrum Network
2. Manually inputting the Arbitrum information into your wallet&#x20;
