01 / FIREPrepared for the heat.
Physical marks on 316L steel provide a different medium for environments where paper is vulnerable.
SECURITY, WITH CONTEXT
Security is not a claim.
It is a system.
Your wallet protects signing. Plate B preserves recovery information. Materials, accurate recording and secure storage all play a part.
316L / 3 MM SOLID STEEL
FOUR REAL-WORLD CONDITIONS
Made for the physical world.
Steel. Physical marks. No electronics.
01 / FIRE
02 / SALT MISTBuilt with corrosion in mind.
316L stainless steel is selected for corrosion resistance and long-term storage. Safe storage still matters.
03 / WATERThe record stays in the metal.
Your finished backup is a pattern of punched dots. Reading it needs no paper, ink or electronic components.
04 / IMPACTOne solid plate. No loose letters.
A 3 mm one-piece construction. Once punched, the record becomes part of the plate itself.
Brand-published test references include 1300°C, 20-ton compression and ASTM B117 salt spray. These are specific claims, not universal guarantees. Ask support for the applicable test conditions and reports.
02 / KNOW THE DIFFERENCE
Choose the medium.
Understand the risks.
| Consideration | Paper | Digital | Plate B |
|---|---|---|---|
| Medium | Paper and ink | Digital files | 316L metal and physical marks |
| Power to read | No | Typically yes | No |
| Remote exposure | No network interface unless digitized | Depends on the device and storage method | No network interface on the plate |
| Fire, water & environment | Vulnerable to material and storage conditions | Depends on hardware and backups | Designed for physical resilience; limits remain |
| Loss or theft | Still a risk | Still a risk | Still a risk; secure storage required |
03 / YOUR PART OF THE SYSTEM
Self-custody.
With responsibility.
Offline is not theft-proof.
Plate B does not encrypt its contents. Anyone obtaining enough recovery information may access your assets. Location and access control matter.
Durable is not indestructible.
Temperature, duration, chemicals, impact and marking quality can all affect outcomes. One demonstration is not a guarantee for every situation.
A backup must be readable.
Check order, spelling and marking positions. Verify using your wallet’s official safe procedure and preserve required recovery configuration details.
This site is not a recovery tool.
Never enter recovery words, private keys or a passphrase into this website, support messages or online forms. We will not ask for them.
BEYOND THE DEVICE
Yours today.
Yours tomorrow.
Make your next wallet change just a change of device. Give your recovery information a physical backup.
