When restoring your Arculus Wallet, step 3 of 4 introduces a new screen which asks you to select Cardano Standard or Cardano Legacy for your wallet. It is important to follow the guidelines in this article in determining which option to select when restoring your wallet.

If you held Cardano as an asset in your Arculus Wallet prior October 19, 2023 (release of Arculus iOS app version 3.3) and are restoring your wallet, please select Cardano Legacy during Step 3 of the Restore process. Once your wallet has been restored, select ADA from the Assets menu, allow a few minutes for the Arculus app to sync with the blockchain and then confirm your ADA balance is displayed.

If you do not hold Cardano in your Arculus wallet or if you sent Cardano to your Arculus wallet for the first time after October 19, 2023 (or updating to iOS app version 3.3), select Cardano Standard during Step 3 of the Restore process. 

If you encounter any issues sending ADA or viewing your ADA balance in your Arculus wallet, please restore your wallet and select Cardano Legacy during Step 3 of the Restore process. That should resolve the issue for you.
