Secure, Simple, and Self-Custody.
Turn your spare phone into an impenetrable Cold Wallet. Protect your crypto assets by storing your private keys completely offline.
The Wall Free Finance Foundation brings you an zero-connection security solution that puts you back in the driver’s seat.
The Concept
More Than An Ordinary Hardware Wallet
Security shouldn’t require expensive proprietary hardware. WallFree utilizes a Two-Device Approach to separate your keys from the internet, increasing both security and usability.
📱 Device 1
The WallFree Vault
The Fortress. This app is installed on a dedicated, spare smartphone. It remains completely offline—zero-connection from WiFi, Bluetooth, and cellular data.
- Role: Generates keys, signs transactions, and stores secrets.
- Connectivity: None. It never touches the internet.
📲 Device 2
The WallFree Wallet
The Bridge. This is the companion application installed on your everyday smartphone.
- Role: Prepares transactions and broadcasts them to the blockchain.
- Security: It is “blind”—it is never aware of your private keys or secrets.
How It Works
Zero-Connection Security in 3 Steps
Initiate
Create a transaction on your WallFree Wallet (Online Phone). It generates a QR code.
Sign
Scan the QR code with your WallFree Vault (Offline Phone). The Vault signs the transaction securely offline and displays a signed QR code.
Broadcast
Scan the signed QR code back with your WallFree Wallet. The transaction is broadcast without your private keys ever leaving the offline device.

We combine ease of use with the rigorous technical standards required by crypto veterans.
