Secure Element Chip: Bank-Grade Protection
At the heart of Vaultix is a certified Secure Element (SE) chip-the same technology used in credit cards and passports. This dedicated cryptographic processor isolates your private keys from the main device processor, creating an impenetrable barrier against malware, physical attacks, and supply chain tampering.
Unlike software wallets that store keys in vulnerable device memory, the Secure Element never exposes your keys to the operating system. All cryptographic operations happen inside the chip's protected environment.
What is EAL6+ certification? The Common Criteria Evaluation Assurance Level 6+ is one of the highest security certifications available for commercial products. It requires rigorous testing against side-channel attacks, fault injection, and physical penetration attempts.
Technical Specifications
| Chip Type | Secure Element (SE) |
| Certification | EAL6+ (Common Criteria) |
| Key Storage | Hardware-isolated, tamper-proof |
| Cryptographic Algorithms | ECDSA, EdDSA, Schnorr, BLS |
| Random Number Generation | True RNG (TRNG) |
| Side-Channel Protection | DPA/SPA countermeasures |
| Physical Tampering Detection | Active shields, mesh sensors |
Why This Matters: Software wallets and unprotected hardware devices can be compromised if malware gains access. A Secure Element makes key extraction computationally infeasible-even with physical possession of the device.
Offline Transaction Signing: Step-by-Step
Your private keys never connect to the internet. Every transaction is signed offline and verified on-device before broadcast.
Create Transaction
Using the Vaultix desktop or mobile app, compose your transaction: recipient address, amount, gas fees. The app connects to the blockchain to fetch current balances and fee estimates.
Transfer to Hardware Device
The unsigned transaction data is sent to your Vaultix wallet via USB or Bluetooth. Only transaction details cross this connection-never your keys.
Review & Confirm On-Device
Vaultix displays the full transaction on its secure screen: recipient address, amount, network fees. Verify every detail matches your intent. Malware cannot alter this display.
Sign Inside Secure Element
After physical confirmation (button press or PIN entry), the Secure Element cryptographically signs the transaction using your private key. The key never leaves the chip.
Broadcast Signed Transaction
The signed transaction returns to your app, which broadcasts it to the blockchain network. Your keys remain offline throughout the entire process.
🛡️ Air-Gap Guarantee
Even if your computer or phone is infected with malware, attackers cannot steal your keys. The worst they can do is request signature of a malicious transaction-which you'll see and reject on the Vaultix screen before signing.
Multi-Chain Support: One Device, All Your Assets

Future-Proof Design: New blockchains and token standards can be added via firmware updates. You won't need to buy new hardware as the crypto ecosystem evolves.
Encrypted Backup and Recovery: Never Lose Access
Losing your device doesn't mean losing your crypto. Vaultix implements industry-standard BIP39 seed phrases with optional advanced protection layers.
📝 Initial Backup Process
- Generate Seed Phrase: Vaultix creates a 24-word BIP39 mnemonic using true random number generation from the Secure Element.
- Write Down Offline: Record your seed phrase on the included recovery card. Never photograph or digitally store it.
- Add Passphrase (Optional): Add a 25th word memorized passphrase for additional security. Even if someone finds your seed phrase, they can't access funds without the passphrase.
- Verify Backup: Vaultix prompts you to re-enter random words to confirm accurate recording.
- Secure Storage: Store recovery card in fireproof safe, safety deposit box, or distributed Shamir secret shares.
🔓 Recovery Process
- Obtain Replacement Device: Purchase new Vaultix or compatible BIP39 hardware wallet.
- Select "Restore Wallet": Choose recovery mode during device initialization.
- Enter Seed Phrase: Input your 24-word seed phrase using the device interface.
- Enter Passphrase: If you set a 25th word, enter it now.
- Derive Accounts: Vaultix re-derives all your accounts and addresses. Your full balance reappears.
⚠️ Critical Security Warnings
- Never Digital: Never store seed phrases in cloud storage, email, notes apps, or photos. These can be hacked.
- Physical Security: Treat your recovery card like cash. Anyone with physical access can steal your funds.
- Shamir Backup: For large holdings, use Shamir Secret Sharing to split your seed into multiple shares (e.g., 3 of 5 required). Distribute to trusted locations.
- Test Recovery: Before depositing large amounts, practice recovery on a separate device to verify your backup works.
Open-Source Firmware: Audit-Ready Transparency
Closed-source wallets require blind trust. Vaultix's firmware is fully open-source on GitHub, enabling independent security audits and reproducible builds. See exactly what runs on your device.
Why Open-Source Matters for Hardware Wallets
