In a world where wallets are getting smarter but attacks are getting sharper, true cold storage remains the gold standard of crypto security. The Zypto Vault Key Card (VKC) takes that foundation and rebuilds it for the DeFi era, a mobile first cold wallet designed not just to store keys offline but to protect your entire Zypto App ecosystem.
The VKC connects security with usability, bringing cold wallet protection directly into the DeFi environment without cables, chargers, or compromise.
Cold Wallet Protection for Every User
The Vault Key Card gives Zypto App users an extra layer of real world protection that traditional hardware wallets don’t match. It doesn’t store your full private key. Instead, it uses a split key architecture, meaning the card holds only part of your cryptographic secret. The remaining data stays encrypted within Zypto App, ensuring that no single device ever contains your complete key.
This approach eliminates a single point of failure while keeping access quick, secure, and private. It’s cold wallet security – re-engineered.
How the Vault Key Card Works
When you authorise a transaction, the card communicates with Zypto App through contactless NFC, combining both encrypted halves temporarily to verify your identity and sign the action. No keys are ever displayed, exported, or connected to the internet.
It is the essence of a cold wallet, offline protection with on demand usability.
Mobile First, Cable Free, Always Ready
The Vault Key Card removes everything that slows down conventional hardware wallets. No cables to carry, no USB ports to find, no pc to use, no batteries to charge, and no firmware updates to maintain. Just instant authentication through your phone.
It is as simple as tapping your card on your device to confirming the transaction, and you’re done. The card itself is the authenticator, powered entirely by the NFC connection during use, making it immune to remote access or network attacks.
Cold Wallet Security, Built for the Zypto Ecosystem
The Vault Key Card is part of the broader Zypto security ecosystem. Inside Zypto App, users can manage wallets, swap across more than 20 blockchains, use crypto cards accepted globally, pay bills in over 120 countries, and reload mobile data, all within a self custody framework anchored by VKC.
Each card can protect up to three DeFi wallets in Zypto App, securing not just a few assets but potentially your entire crypto portfolio. The Vault Key Card safeguards every coin and token currently supported in Zypto App – over 24,000 digital assets across more than 20 blockchains and counting.
Whether you hold Bitcoin, stablecoins, or the latest DeFi tokens, VKC extends true cold wallet protection to, quite possibly, everything inside your multichain Zypto wallets.
Built for Every Type of Holder
The Vault Key Card is not just for whales or long term investors. It is designed for everyone who uses Zypto App, whether you hold a few tokens or a full multichain portfolio.
It provides physical control over your cryptographic identity while keeping the user experience simple enough for everyday use. No logins, no passwords, and no recovery phrase to expose online. Just a private, contactless key that belongs to you and only you.
The mobile-first design means you can use it anywhere life takes you. Your wallets and assets are always stored cold and safely offline, but you can authorise a transaction with just a tap.
The Next Chapter in Self Custody
Traditional cold wallets work by keeping your private keys completely isolated from the internet, disconnected from networks, apps, and online threats. That isolation keeps assets safe but also limits how and where you can use them.
Vault Key Card changes that model. It keeps your keys completely offline while connecting safely to Zypto App through contactless NFC when you need to approve an action. It’s cold wallet protection through controlled connection, combining true offline security with full DeFi access.
It is not just another hardware wallet. It is the foundation of Zypto’s self custody stack, designed for a world where crypto is not just held but used.
The Vault Key Card is available to order directly inside Zypto App, with next day international shipping. And, if you have ZYP rewards, you can pay or part pay with those.
