Creating a Monero Cold Storage wallet using Feather Wallet involves setting up an offline (air-gapped) computer to securely store your private keys, ensuring they remain isolated from potential online threats. This method enhances the security of your Monero holdings by preventing unauthorized access.
Requirements:
- Offline Computer: An old laptop or desktop, ideally with a webcam, designated to remain permanently offline.
- Online Computer: Your regular internet-connected device.
Step 1: Prepare the Offline Computer
- Install a Linux Distribution: For enhanced security, install a lightweight Linux distribution such as Tails, PeppermintOS or MX Linux on your offline computer.
- Disable Network Interfaces: Physically remove or disable Wi-Fi and Bluetooth modules to ensure the device remains offline. This can often be done through the BIOS settings or by physically disconnecting the hardware.
Step 2: Install Feather Wallet on the Offline Computer
- Download Feather Wallet: On your online computer, download the latest version of Feather Wallet from the official website.

- Securely Store Seed Phrase: Write down the 25-word seed phrase on paper and store it in a secure location. This seed is crucial for wallet recovery.
- Set Wallet Password: Choose a strong, unique password to encrypt your wallet file.

Step 6: Prepare to Send Monero
- Create Unsigned Transaction: In the view-only wallet on your online computer, initiate a transaction and save the unsigned transaction file.
- Transfer Unsigned Transaction: Use a USB drive to move the unsigned transaction file to your offline computer.
Step 7: Sign the Transaction Offline
- Open Feather Wallet Offline: On your offline computer, open Feather Wallet and load your wallet.

Security Considerations:
- Maintain Offline Status: Ensure the offline computer remains disconnected from all networks at all times to protect your private keys.
- Secure Backups: Store your seed phrase and any backups in secure, offline locations to prevent unauthorized access.
- Verify Software Integrity: Always verify the integrity of downloaded software by checking cryptographic hashes to ensure authenticity.
By following these steps, you establish a secure cold storage solution for your Monero holdings using Feather Wallet, minimizing exposure to online threats.
