【Tutorial】How to make a multi-chain cold wallet with a brand-new iPhone + TP Wallet?
(You can use any wallet to do this; I’m using TP Wallet as an example.)
If you want to store crypto assets such as BTC, ETH, TRON, and SOL for the long term, you can look into a cold wallet setup using an “offline signing phone + online watch-only wallet.”
This guide walks you through the entire process, step by step, from scratch.
1/9|What you’ll need
Prepare two phones:
A phone: A brand-new iPhone, dedicated to offline signing
B phone: A phone you use online every day to check balances, build transactions, and broadcast them
Core principle: Keep private keys on the offline device. The online device should only handle public addresses and transactions awaiting signatures.
2/9|Set up the iPhone
① Complete the initial iPhone activation
② Set a sufficiently strong passcode
③ Don’t restore a full backup from an old phone
④ Verify the app’s source through official TP channels
⑤ Once the necessary installation and setup are complete, proceed to offline operation
Note: A brand-new phone is not necessarily completely secure, and turning off the network does not guarantee that the device is free of malware.
3/9|Set up the offline device
On phone A:
• Turn on Airplane Mode
• Turn off Wi-Fi and Bluetooth in the system settings
• Don’t insert a SIM card
• Don’t sign in to cloud services
• Don’t install apps from unknown sources
After checking the network status, create a wallet using the cold wallet process officially supported by TP.
Don’t simply disconnect an ordinary wallet from the internet and assume it can safely sign transactions offline.
4/9|Create a wallet and back up the recovery phrase
Create a wallet using the cold wallet process supported by the current version of TP.
• Generate the recovery phrase in a private setting
• Write it down by hand in the correct order
• Check the spelling and order of each word
• Store the backup securely
Don’t take screenshots
Don’t save it in Notes, cloud storage, or messaging apps
Don’t enter the recovery phrase on any unfamiliar website
Don’t disclose your private key or recovery phrase to anyone
Remember: Whoever has your recovery phrase may be able to control the associated assets.
5/9|Create an online watch-only wallet
On phone B:
① Open TP Wallet
② Find the option to import a watch-only wallet
③ Enter the public wallet address associated with phone A
④ Verify the address and blockchain network
A watch-only wallet lets you view assets and prepare transactions. It doesn’t require importing the cold wallet’s recovery phrase or private key.
For a multi-chain wallet, verify the address and support status for each target chain, such as BTC, ETH, TRON, and SOL.
6/9|How does offline signing work?
The usual process is as follows:
Phone B: Enter the recipient address, amount, and fee, then generate a QR code for the transaction awaiting a signature.
Phone A: Keep the phone offline, scan the QR code, verify the transaction details, and sign it.
Phone B: Scan the signed result, confirm the transaction, and broadcast it to the blockchain.
Finally, use the transaction hash and a block explorer to confirm that the funds have arrived.
Before signing, verify the recipient address, amount, network, fee, and contract call. Cancel immediately if any information is incomplete or unusual.
7/9|What should you know about multi-chain assets?
Different blockchains may use different address formats, key derivation paths, and signing mechanisms.
• BTC: Verify the address type and derivation path
• ETH / BNB Chain: Verify the chain ID and transaction details
• TRON: Verify the TRON address and fees
• SOL: Verify the Solana address and signing support
Don’t assume that because it works on one chain, the same offline signing process will work on every chain.
Refer to the current TP version and the official documentation for the relevant blockchain for details about supported features.
8/9|Restore your backup and test security
Before transferring in a large amount of assets:
Verify your recovery phrase backup
Confirm the wallet recovery process
Verify the address for each chain
Start with a small test transaction
Confirm that the transaction is successfully recorded on-chain
Store the backup in a secure, separate location
Don’t enter your only copy of the recovery phrase on an online phone just to test the recovery process.

This tutorial is a security reference. It does not mean that the current TP iOS version supports a unified offline signing feature for all blockchains.
If you plan to store a large amount of assets, consider evaluating a professional hardware wallet.
A truly secure cold wallet is about more than being offline: it also requires private key protection, independent signing, reliable backups, and rigorous verification.
