If you are looking to use the latest version of TronLink or want to migrate to a new device, you might have to upgrade the cold-wallet end of your TronLink App. Here are the steps to guide you through the process.
For security assurance, the process requires three mobile phones:
Phone A: The current device of your cold wallets
Phone B: The new device for your cold wallets (upgraded version)
Phone C: The hot wallet interface for managing cold wallets on both Phone A and Phone B
Preparation Steps
1. Back up cold wallet data
- Before starting, ensure the crucial data of your cold wallets on Phone A, including mnemonics and private keys, has been reliably backed up.
- Use a secure backup method, like manually noting down the information and keeping it in a safe place (e.g., a safe or a water and fire-proof storage box).
- Important: Never store your mnemonics and private keys on any Internet-connected device to prevent potential hacking.
2. Prepare a new device
- Get Phone B ready, which should be either brand-new or has been reset.
Update TronLink
3. Install the latest version of TronLink
- Briefly connect Phone B to the Internet and download the newest TronLink version through official channels (App Store or Google Play). Once the installation completes, disconnect Phone B from the Internet.
- Enable airplane mode or turn off Wi-Fi and cellular data for Phone B, and maintain this offline state for subsequent steps.
4. Import cold wallets
- Open TronLink on Phone B, and tap "Switch to Cold Wallet Mode".
- Choose one of these import methods:
- Manually enter the mnemonic or private key, choose the target address, and then tap "Import Mnemonic" to confirm import and enter TronLink's homepage.
- Open the QR code of the mnemonic or private key on Phone A, and use Phone B to scan and import the cold wallet.
The following figure illustrates the specific steps.
a.Tap to Switch to Cold Wallet Mode.
b.Tap to Import Wallet
c.Tap to scan the QR code, or enter it manually.
d.Set a name and password to finish.
- Important: When scanning or entering the mnemonic, private key, or Keystore file, make sure you are in a completely safe environment.
Steps After Update
5. Verify imported addresses
- After importing cold wallets to Phone B, tap the wallet switching button to confirm whether the addresses match those on Phone A.
a.Tap the wallet name in the top-left corner.
b.You can verify the address on this page.
- If the addresses do not match, stop immediately and verify all mnemonics or private keys.
6. Test wallet functionalities
- Perform a small test transfer between the hot and cold wallets to confirm everything works correctly on the new device.
- Initiate the transfer on Phone C and use Phone B for signature. For more information about the signing process, refer to the cold wallet user guide.
- Confirm receipt of the transfer.
Follow-up Steps
7. Handle the old device
- Options for Phone A:
- Retention: Keep it in a safe, offline environment;
- Disposal: Reset the phone to erase data and physically remove the storage medium (e.g., remove the chip).
- Important: Ensure that no data is leaked or retained when wiping the original device.
