The device can work together with the PC software (OPOLO Desk) to perform different functionalities. 1.2Acronyms and Abbreviations Mnemonics / Seed – 24 words that are stored securely inside the device, used to generate wallet Wallet – Blockchain wallet that stores the private keys for different block chains User’s ManualPage 5 2.0 System Summary 2.0SYSTEM SUMMARY User’s Manual 2.0 System Summary 2.0SYSTEM SUMMARY 2.1System Configuration The OPOLO Cosmos powers up only when connected via a USB to the desktop PC. The user also need to install the OPOLO Desk software to communicate with the device. 2.2User Access On first time startup, user needs to setup OPOLO Cosmos password. The password can be changed later on. The user will be asked to enter password twice to setup, after setting up, each time user would be asked to enter password when the device turns on, and when the user wants to access its walelt. The password entry screen is shown here: User’s ManualPage 7 2.0 System Summary User’s ManualPage 8 3.0 Getting Started 3.0GETTING STARTED User’s Manual 3.0 Getting Started 3.0GETTING STARTED 3.1Setting up OPOLO Desk To communicate with OPOLO Cosmos, user needs to setup OPOLO Desktop app on his/her PC. Download the OPOLO Desk app from the www.OPOLO.io and install it on the PC. 3.2Create a wallet After setting up password on OPOLO Cosmos, open the OPOLO Desk software and go to the settings page as shown above. You must see a notification that the hardware wallet is connected. If you do not see this notification, then unplug and plug the OPOLO Cosmos and enter your password. Once the OPOLO Cosmos established the USB connection with desktop and you can see the notification on OPOLO Desk that the wallet is connected, then go to settings page, and press “Create New OPOLO Wallet” button. Follow the instructions on OPOLO Cosmos and complete the setup process. You will see the screens as shown below. User’s ManualPage 10 3.0 Getting Started User’s ManualPage 11 3.0 Getting Started During the setup, you will be shown mnemonics (24 words) that you can take backup using two ways. One you must write the seed word on the paper and save it on a secure place. The mnemonics will be shown 2 times on the OPOLO Cosmos, so you can make sure that you have written them correctly on the paper, you can take multiple paper backups to be sure. Once move to next screen, you would not be able to come back to the mnemonics backup screen. So make sure that you have taken proper backup before moving forward. Secondly you may can use OPOLO Card to store the seed backup by touching the OPOLO Card on the back side of the OPOLO Cosmos. You can take backup on OPOLO Card when you see the following screen: Touch the card on back of OPOLO Cosmos and press the button Backup. If the backup is securely saved on the OPOLO Card then you will see a success message on OPOLO Cosmos. You may can take multiple backups if you have many OPOLO Cards by touching on back of the OPOLO Cosmos and pressing the Backup button. Once you press the Skip/Exit button, you cannot come back to this screen hence cannot take backup again. After the successful completion of the above steps, you have created the wallet successfully. User’s ManualPage 12 3.0 Getting Started 3.3Add a Coin/Toke and create address On OPOLO Desk, go to the Coins page using the menu on the left side. And press the “Add Coins/Token” button on top right corner as shown in the figure. On pressing the button you will see a list of coins/tokens that you can toggle to add into the portfolio. You can toggle the Bitcoin option to add the Bitcoin coin into the wallet and this will also generate your first Bitcoin address. Now you need to enter the password on the OPOLO Cosmos, and also enter the passphrase if you want to use any passphrase. Please note down the passphrase so…
