WallFree Vault

WallFree Vault transforms your spare smartphone into an impenetrable, enterprise-grade cold storage wallet. Designed as the ultimate offline fortress for your digital assets, it ensures your private keys never touch the internet—protecting your funds from online hacks, malware, and digital attack vectors.

Operating with zero connectivity (no WiFi, Bluetooth, or cellular data), WallFree Vault works seamlessly alongside the companion WallFree Wallet app. By isolating your secrets from the internet, you can securely sign transactions using only your camera and QR codes.

Key Features:
• 100% Offline Storage: Your private keys are generated, encrypted, and stored on a device that remains entirely disconnected from the web.
• Air-Gapped Signing: Sign transactions via QR codes with absolute peace of mind, ensuring zero digital attack vectors.
• True Entropy Generation: Create your seed phrase using verifiable, physical randomness through interactive coin flips and dice rolls.
• Advanced Cryptography: Supports BIP39 Passphrases for an extra layer of protection and plausible deniability, as well as BIP85 for deterministic child seed derivation.
• Social Recovery Protocol: Regain access to your funds through trusted contacts if you lose your device, without ever exposing your private keys.
• Fully Open Source: Don't trust, verify. Our transparent code is available for anyone to audit.

Note: For maximum security, WallFree Vault is designed to be installed on a dedicated offline device and works in tandem with the online WallFree Wallet app.
