How to interact with my cold wallets?
1. Cold wallet: Select a cold wallet, and click on “Receive” to show the QR code of the cold wallet.
2. Hot wallet mode: Click the "Add Wallet" icon on the top right corner of the homepage, select "Pair Cold Wallet", and then scan the QR code of the cold wallet to add the cold wallet on the Internet-connected device.
3. You can make all types of transactions supported by hot wallets including transfers, TRX staking & unstaking, voting, and multi-signature transaction via the cold wallet on the Internet-connected device. After you initiate a transaction on the Internet-connected device, you will be directed to the QR code page for scanning with the cold wallet mode device.
4. Use the cold wallet on that device to scan the QR code above and sign the transaction in the cold wallet. After that, another QR code is displayed on the cold wallet mode device.
5. Scan the QR code of the cold wallet with the Internet-connected device to complete the transaction.
