Made in Germany
The SEEDOR Safe provides a secure and permanent way to store your Bitcoin recovery seed in extremely durable stainless steel.
The Challenge
To store Bitcoin securely, all you need is a 12- or 24-word seed phrase. This seed phrase should never be stored on a computer, in the cloud or in a password manager. Instead, always keep it offline. In stainless steel.

Flooding or a burst pipe. The ink fades, the paper disintegrates. The 316L stainless steel remains intact.
What is clearly legible today can become a riddle tomorrow. Embossed with machine lettering in stainless steel, there is no mistaking or forgetting.

Why SEEDOR?
There are many Bitcoin steel wallets available. However, for us, the perfect solution wasn't among them. That's why we developed SEEDOR. But what exactly differentiates us from other Bitcoin backup solutions?
Four letters are sufficient, but only if you know which Mnemonic Seed was used. That's why our discs have space for the full word length.
A word and the sequential number are engraved into each plate. Even if the safe is damaged and plates fall out, the wallet can be restored this way.
Are you creating a new wallet? In the SEEDOR system, this will cost you less than 10 EUR. Simply buy new discs, engrave them, and replace them.
The SEEDOR Safe holds up to 40 discs in a compact stainless steel capsule. This fits in any safe, any drawer, any bank safe deposit box.

Compatibility

Frequently Asked Questions
The SEEDOR Safe allows you to store Bitcoin and other cryptocurrencies securely and permanently by storing your recovery seed in solid stainless steel. With the help of the Starter Kit you can discretely and independently of third parties emboss your seed into solid stainless steel plates and then store it securely in the SEEDOR Safe on your own.
Your Bitcoin seed phrase is a sequence of 12 or 24 words that can restore your wallet independently of the device. If you lose it, you lose access to your Bitcoin forever. Secure storage in stainless steel protects against fire, water, and decay.
Many metal backups truncate each word to four letters because the BIP39 standard technically allows it. In practice, this leads to confusion and reading errors. Anyone who has to restore their wallet in an emergency should not have to rely on a word like ABAN when the full word ABANDON would be unambiguous.
Unlike tile systems, where loose letter tiles can get lost, each disc in SEEDOR remains individually reconstructible. Each disc not only carries the word but also its position as a number. Even after a fire or fall, you can restore the order using the numbers.
All elements of the SEEDOR Safe are made from the finest V4A stainless steel (AISI 316L or 1.4404). To prevent contact corrosion, care is taken to ensure that all elements are manufactured with exactly the same alloy.
The SEEDOR Safe works with all wallets that follow the BIP39 standard. This includes Ledger Nano, Trezor, BitBox02, Coldcard, Blockstream Jade, Sparrow Wallet, Specter, Electrum, and many more. In addition, we support Shamir Backup SLIP39 and Monero's 25-word seed.
On average 20 minutes for a 12-word seed and 50 minutes for a 24-word seed. You emboss the discs with the supplied letter punches, stack them in the specified order into the capsule, and seal it with the tamper-proof sticker.
The best embossing results are achieved on a solid, hard surface, such as a workbench, a solid parasol stand, or a stone floor. We advise against embossing on brittle surfaces such as tiles or granite floors.
We ship all orders within Germany with DHL. For additional anonymity, you can also have your shipment sent to a DHL Packstation.
