What happens if I send my funds from Arb1 to another network without using a bridge?

Please make sure you use the arbitrum bridge when transferring funds from the Arbitrum One chain to another chain. Otherwise, you need to ensure that the destination wallet\exchange supports the Arbitrum One network.

If you send the funds and the receiving wallet\exchange does not support the Arbitrum One network, there is unfortunately nothing that we can do to recover your funds. You would need to contact the wallet\exchage support and see if they can do anything to help you retrieve the funds.
