Keepcrypt Cell — titanium-cored AAA-form seed storage

Every crypto metal seed backup on the market is recognisable as a metal seed backup. Fire, corrosion and water were solved years ago for protection. Being found was not. Until now.

MATERIAL TITANIUM GRADE 2

The metal plate or capsule with crypto branding in your vault is a treasure map.

A stranger finds one of these. Which one tells them you own crypto asset?

Three objects. Pick the form that fits where you hide.

Each object stores part of a BIP39 seed phrase on titanium inside an ordinary shell.
No single object looks like seed storage.
No single object needs to hold the entire phrase.

Keepcrypt Cell

The battery that holds your seed.

5 pentagon beads of Titanium Grade 2, sealed inside a stainless AAA shell. Each bead stores one BIP39 word, first 4 letters on 4 faces, sequence notch on the 5th.

Durability solved a problem we already had

The remaining problem is what happens when someone finds it. Keepcrypt does not replace your steel plate or other metal storage solution's durability, it replaces the assumption that durability is enough.

Frequently Asked Questions

Stamped steel plates and metal capsules solve fire and water. That has been solved since 2017. Nobody solves the discovery problem. A stamped plate found in a drawer is recognizable as crypto storage in three seconds. A KeepCrypt object found in the same drawer reads as a battery, a fastener, or a hinge. Finding it is not the same as reading it.

Any wallet that produces a BIP39 seed phrase. Ledger, Trezor, Coldcard, BitBox, Keystone, Foundation Passport, Blockstream Jade, plus software wallets and DIY signers like SeedSigner and Krux. KeepCrypt stores the phrase, not the device.

Each Cell and each Screw holds 5 pentagon beads on a titanium post. You scribe the first 4 letters of each BIP39 word on 4 flat faces of a bead, plus a sequence notch on the 5th. The Hinge holds 12 words on a single titanium pin engraved in 12 sequential segments. To read: open the object, lay the beads or pin in order, read 4 letters per segment. Setup takes about 15 minutes per pack. Each pack ships with practice pieces and a carbide pen.

Every pack includes practice beads. The carbide pen is forgiving on Ti Grade 2: mis-strikes are visible immediately, and you re-do that bead before threading. If you damage a real bead after engraving, replacement blank beads are $19 per 5-pack. The Cell and Screw are reusable, the body is unchanged, you swap in fresh beads. The Hinge uses a 12-segment titanium pin core; replacement pins are $79.

Yes. Titanium Grade 2 melts at 1668°C, SS 304 at 1400°C. Both sit above a fully developed room fire, which runs 700 to 1200°C (NFPA 921).
