Open the Gluwa mobile app.
Open the wallet with the password you used to create the wallet.
Navigate `Menu -> Private key and address`
Submit your password again to review your private key and address.
You will see the private key and address of your Gluwacoin wallets (e.g., USD-G, KRW-G) which are Ethereum wallets. Note that you will see the same private key and address for all Gluwacoin wallets since they coexist in the same Ethereum wallet.
