Reviews
“Easy to use and reliable for seed phrase storage. I have mine buried in the backyard and it's perfect for secure storage. Fits well in any safe or vault. The metal is high quality and it should last a long time. Good value for self custody crypto owners.”
-Neil Patel.
“The inclusion of a tracker slot is a brilliant addition, allowing a physical tracker to be paired with the unit for an extra layer of asset management.”
-Sam Hofmann.
“We are very much novices with all things crypto. It was recommended that we look into more reliable and secure seed phrase storage, rather than rely on pen and paper methods. This Crypto Seed Storage seems to be a much better option.”
-TDMac.
“This is the ultimate cold storage solution. 304 steel has a crazy high melting point, so my recovery words are safe. The tiles are clearly etched. I like the metal seed phrase plate.”
-ECKYWOODS.

FAQ
Does adding an AirTag make my seed phrase storage vulnerable to hacking?
No. The AirTag and your seed phrase are 100% air-gapped. Your recovery phrase is etched in 304 steel—no chips or Wi-Fi. No hacker can "download" metal. The AirTag only provides a location signal. It's total offline security for your private keys.
Is this compatible with my Coldcard or Trezor 24-word phrase?
Fully compatible with BIP39 wallets like Ledger, Trezor, and Coldcard. It follows the 4-letter international standard to secure any 12 or 24-word seed phrase. The professional choice for any hardware or software wallet recovery.
How secure is the locking mechanism on this steel version?
We use a reinforced locking bar for a zero-tolerance fit. Once bolted, the 304 steel tiles are physically locked in. Even under high impact or thermal expansion in a fire, your 24-word seed remains indexed and readable.
Can I store this crypto seed phrase storage in a damp environment or underground safe?
Absolutely. 304 Stainless Steel is highly resistant to rust, corrosion, and acid. Perfect for humid basements or long-term safety deposit boxes. Your private keys are protected against environmental decay for decades.
