• Set Up Your Wallet: Follow the prompts to create a new wallet or import an existing one. Make sure to securely store your recovery phrase.
• Ensure Sufficient ETH: You'll need some ETH in your wallet to cover transaction fees when switching networks. Check your balance and ensure it's adequate.

Once you've switched to Arbitrum, you can start using it for transactions. Here's what you need to know:
