In crypto, self-custody is power, but only if your keys stay truly yours.
Too many wallets store the full seed phrase on an internet-connected device. That makes them “hot”, even if they look secure. All it takes is one phishing link, compromised extension, or rogue app, and your private key / seed phrase is suddenly exposed.
The Zypto Vault Key Card (VKC) changes that. It turns any wallet created in the Zypto App into a true cold wallet – where your key is split, your signing is secure, and your assets stay offline until the moment you choose to act.
Your Keys, Cold. Always.
Unlike hot wallets that leave your private keys / seed phrase exposed to remote attacks, the VKC keeps them cold, and completely disconnected from the internet.
In fact, your key is never fully stored anywhere. Thanks to our split-key architecture, part of it lives on your phone, part on the card, and the full key never exists unless you sign a transaction.
Add 3FA. Lose the Worry.
The VKC doesn’t just go cold – it goes triple secure. Our Three-Factor Authentication (3FA) combines:
- A personal PIN
- A physical tap of your Vault Key Card
- And optional biometrics on your phone
No signature happens unless all three agree. It’s like having a safe, inside a vault, inside a locked building.
Mobile-First. Cable-Free. Zero Fuss.
The Vault Key Card is designed for how people actually use crypto – on the go, not chained to a desktop.
- Tap-to-sign transactions right from your phone
- No cables, dongles, or adapters required
- Set up in seconds, no new wallet needed
- Ultra-portable, credit-card sized design
- Fully integrated with the Zypto App
Protect One Wallet – Or Three
Have multiple wallets? No problem. A single VKC can secure up to three DeFi wallets in Zypto App – perfect for managing different accounts while keeping them all under one layer of protection.
Supports Every Token That Matters
The VKC doesn’t just guard Bitcoin or Ethereum. It safeguards over 24,000 digital assets and counting. Every token on every supported chain is protected.
In fact, we challenge you: try to find a token on a supported chain that VKC doesn’t cover.
Stay Safe. Stay Sovereign.
The VKC is self-custodied. No third parties. No recovery phrases sent anywhere. If your card or phone is lost, you can recover securely by entering your seed phrase again – you stay in control the entire time.
Your keys. Your card. Your move.
