How to connect Arbitrum on MetaMask?

MetaMask supports several other networks besides Ethereum. However, they are not enabled by default and must be added manually. To add Arbitrum on MetaMask, you need to provide some network data:

1. Open MetaMask and click the network dropdown menu near the MetaMask fox logo.
2. A pop-up will appear, then click “Add Network.”
3. On the next page, you’ll need to add the following Arbitrum network data:
