Security Spotlight: How the Vault Key Card Keeps Your Crypto Safe

The Vault Key Card - The Cold Wallet Solution from Zypto
May 22, 2025

In a world where digital threats never sleep, the Zypto Vault Key Card (VKC) stands as an unshakeable line of defence for your crypto. Designed to protect what matters most, your private keys, this ultra-secure cold wallet offers physical protection in the digital age.

A Cold Wallet That Holds Its Ground

The Vault Key Card is a fully offline, cold storage solution built to safeguard your digital assets with military-grade security. It stores your private keys completely offline, making them unreachable by hackers, malware or phishing schemes.

No devices. No PC. No cables. No compromise.

Instead of relying on hot wallets or cloud-based vaults, the VKC gives you complete sovereignty over your crypto – backed by tamper-proof architecture, next-generation encryption, and a triple-layered 3FA security model:

  • Your Personal PIN
  • The Vault Key Card itself
  • Optional biometric authentication

Only when all three elements align is a transaction authorised, giving you an iron-clad hold over your funds.

Over 24,000 Coins and Tokens Supported

The Vault Key Card doesn’t just support the big names. With compatibility across 20 major blockchains and over 24,000 coins and tokens, it’s built to scale with your portfolio, whether you’re holding Bitcoin, Ethereum, ZYPTO, or a diverse range of DeFi assets.

How It Works

Your wallets are kept completely offline in cold storage until you decide to transact. When you’re ready to move, you simply:

  1. Initiate the transaction in the Zypto App
  2. Tap your VKC to your device’s NFC reader to authorise
  3. Your private keys temporarily combine (just for a moment) to sign the transaction
  4. Then, your keys are instantly re-split and your wallets return to cold storage

Your keys are never stored online. There’s no digital trace to exploit. Just instant, secure, self-custodial control.

The New Standard in Crypto Security

The Vault Key Card doesn’t just protect your assets, it returns true control to you. In a DeFi landscape still vulnerable to centralised exchange breaches and wallet drain exploits, the VKC offers a radically secure and private solution for all levels of holders.

And with its sleek, travel-ready design and easy integration with the Zypto App, the VKC combines top-tier hardware security with everyday usability.

For the Zypto community, the Vault Key Card isn’t just protection. It’s the hardware backbone of true digital sovereignty.

The VKC is available to order exclusively in Zypto App, for the limited time price of only $75.00.
