The Titanium SteelQR is a premium, open-source-compatible hardware backup solution crafted from Grade 5 titanium (Ti-6Al-4V). At 3mm thickness, it offers exceptional strength-to-weight ratio, superior corrosion resistance, and extreme temperature tolerance—melting point ~1,650°C, with practical fireproof performance in severe conditions well above 1,400°C.
The plate converts a BIP-39 compliant 12-word (C12) or 24-word (C24) seed phrase into a compact QR code format readable only by compatible devices such as SeedSigner, Foundation Devices Passport, Coldcard, or other BIP-39/QR-supporting wallets. This prevents unauthorized scanning on non-compatible readers while enabling fast, secure restoration. For C24 versions, the QR can be permanently marked using a center punch (sold separately) for fully air-gapped, offline permanence.
Variants
- C12: For 12-word seed phrases
- C24: For 24-word seed phrases (supports optional permanent center punch marking)

Frequently Asked Questions
What is SteelQR?
SteelQR is a 3mm 316L stainless steel plate that encodes 12-word (C12) or 24-word (C24) BIP-39 seed phrases as compact QR codes for secure, long-term offline cold storage backups.
How durable is it?
Made from 316L military-grade stainless steel, it is waterproof, corrosion-resistant, and fireproof up to ~1,400–1,500°C before significant degradation—designed to protect seeds for decades in extreme conditions.
How do I use it?
Convert your seed phrase to QR code (using SeedSigner or compatible software), then engrave or mark the QR onto the plate. For C24, optionally use a center punch for permanent, air-gapped storage.
Is it compatible with SeedSigner, Foundation Devices, Coldcard?
Yes—fully compatible with SeedSigner, Foundation Devices Passport, Coldcard, and any BIP-39/QR-supporting wallet. The QR format is readable by these devices for quick restoration.
What if I lose the plate?
If the plate is lost without redundant backups, your seed is unrecoverable. Always create multiple copies in geographically separate locations using best practices from NovaSapien courses.
Can I engrave it myself?
Yes, using a center punch (sold separately) for C24 or manual engraving tools. NovaSapien courses provide guidance on safe, accurate marking.
