The Vault Key Card isn’t just another hardware wallet, it’s a complete rethink of how crypto cold storage should work in 2025.
Your private key is never stored in one place, and even when it briefly assembles to sign a transaction, it’s instantly split again before it can ever be exposed or extracted.
Your Key, Split for Maximum Protection
At the heart of the VKC is a modern split-key system.
This cryptographic design breaks the private key / seed phrase into multiple parts – one held by the card, one by the app.
Neither part can be used alone, and the full key is never stored anywhere.
Even if someone got hold of your phone or your card, without all authentication factors combined, they’d hit a dead end.
3FA: Tap. Scan. Approve.
To authorise any transaction, the VKC offers three layers of authentication:
- Optional Biometrics (fingerprint/Face ID)
- Your App PIN
- A physical card tap
This triple-layered process ensures that you remain the only person who can ever approve access or movement of your funds, even if your device is ever compromised.
Offline. Unhackable. Uncompromising.
The VKC doesn’t plug in, connect to the internet, or rely on firmware updates. Unlike USB wallets, there’s no surface for malware to hijack. No ports. No wires. Just uncompromising security in a sleek, tap-to-sign card.
And, keeping your assets locked in true cold storage, your seed phrase is never stored in full. It briefly assembles only for a second, to authorise a transaction, then is instantly dismantled again.
24,000+ Cryptos. One Cold Wallet.
The VKC supports over 24,000 cryptocurrencies – thousands more than the biggest names in cold storage. Whether you’re holding Bitcoin, stablecoins, memecoins, or niche DeFi tokens, your entire portfolio fits securely in one vault.
