Cryptocurrency has become a popular form of payment, but it’s not always easy to use. You might have to wait several hours or even days before you can send your coins out into the world. In this post, we’ll show you how to transfer crypto without internet connection so that you can send funds quickly and securely.
What is an offline transaction?
An offline transaction is a transaction that is signed by a private key and then sent to a public address. The transaction is not broadcast to the blockchain until it is signed, which means that you can use an offline computer or device to move funds around without ever having them touch the internet.
To understand why this is useful, let’s look at how cryptocurrency transactions work in general:
- Step 1: You want to send money from one wallet address (your own) to another person’s wallet address
- Step 2: Your computer sends out some data called “inputs,” which includes information about how much money you want to send and where those funds came from (i.e., your earlier transactions). These inputs also contain details about what type of currency they represent–for example, Bitcoin or Ethereum–and whether those coins were received as part of an exchange rather than mined yourself.
How to transfer crypto from your hardware wallet to an address in an airgapped computer with a QR code
If you want to transfer crypto from your hardware wallet to an address in an airgapped computer, follow these steps:
- Import your private key into the airgapped computer. This can be done with Electrum or any other wallet software that supports importing private keys.
- Create a new address in the airgapped computer if you don’t already have one there by going to “Receive” and clicking on “New Address”.
- Create a QR code for this new address by going to “Send”, selecting it from the dropdown menu and clicking on “Details”. You may need to click on “Export Private Key” first if you haven’t already done so when creating this new address (see step 1).
Saving your transaction for later verification and signing with a hardware wallet
One of the most important things to remember when transferring cryptocurrency is that you should save the transaction for later verification and signing with a hardware wallet. You can use a paper wallet to store your crypto, or if you’re feeling extra cautious about security, opt for storing it in an offline hardware device like Trezor or Ledger Nano S.
After saving the transaction information, head over to one of these two websites: https://www.myetherwallet.com/#sign-message (for Ethereum) or https://www.coinbase.com/verify_message?id=***
You can transfer cryptocurrency without risking your private key.

You can use a hardware wallet to sign the transaction offline. This is useful if you want to transfer funds from one wallet to another, or if you need to make multiple transactions at once but don’t have access to an internet connection. You’ll need two computers: one which has internet access and another that doesn’t.
On the computer with internet access (the “host”), install Electrum or any other wallet software that supports watching for transactions on an external device (like Trezor). Then connect your hardware wallet via USB cable and open up Electrum’s settings menu in order for it recognize your device as an input source (you may need some extra drivers). Now go back into Electrum’s main window and choose “Receive Coins” from under Send/Receive>>Coins tab then select “Watch-Only Addresses” from dropdown menu below Watch Only Address field where it says New Watch Only Address: Enter this address into QR code scanner on Host computer
Conclusion
By following these steps, you are able to transfer your crypto without risking your private key. You can use this method for any cryptocurrency and any hardware wallet. Once the transaction is complete, it will show up in your online wallet balance when you next connect it to the internet.
