Problem scenario
You are trying to send ENJ to a different wallet/address. You see "Address isn't valid." What should you do?
Possible Solution #1
Double check you have the right address to receive ENJ.
Possible Solution #2
Initially ENJ used an Ethereum block chain. It now uses its own Enjin Relaychain. You may have to transfer a stablecoin or other coin to a platform or wallet and do a swap there.
