so its just stored like any other ECR20 token on same ETH address ?
I don't know as I'm not following this fork. If it's a ERC20 token, you will receive them in your address in the ETH chain. If it's a fork (like what happened with ETC), your address will have the same amount of coins in both chains (the normal ETH and this ETZ), so you will need to export your private-key and import it into a ETZ wallet to spend them.
