How to create a highly secure Crypto Assets cold storage solution without spending a penny? An idle old phone can come in handy!

By following these simple steps, you can turn your old iPhone into a secure Crypto Assets storage device that never connects to the internet:

[Security Features]
• Completely offline storage, eliminating the risk of network attacks
• Cold and hot wallet collaborative working mechanism
• Dynamic QR code signatures provide security assurance for transactions

[Specific Operating Procedure]
1. Prepare an idle iPhone and perform a complete factory reset.
2. Temporarily log in to your Apple account and download the TokenPocket app from official channels (be sure to confirm that the developer is TP Global LTD)
3. After the installation is complete, perform security isolation: log out of the iCloud account, delete all Wi-Fi network connection information, turn off Bluetooth, and ensure the phone has no SIM card.
4. Import your private key or create a new wallet in this completely offline environment.
5. During trading operations: Use a daily mobile phone as an observation wallet to monitor accounts. When authorization for a transaction is needed, complete the signature confirmation by scanning the QR code with a cold wallet.

This homemade cold wallet solution is both cost-effective and provides bank vault-level security for your digital assets. In the current environment of frequent cyber attacks, offline storage is one of the most reliable ways to protect your Crypto Assets.
