What Is the Seedor Safe?

Your seed phrase is the only thing standing between you and losing your Bitcoin forever. Paper burns at 233°F. Your phone gets hacked. Your notes app syncs to someone else’s cloud. The Seedor Safe solves all of it — permanently, in 316L marine-grade stainless steel.

The Seedor Safe Starter Set is a complete Bitcoin seed backup kit from Germany. You stamp your recovery words directly onto stainless steel discs using the included hammer and letter stamps. Load them in order into the sealed capsule. Seal it. Done. Your seed phrase is now fireproof, flood-proof, corrosion-proof, and completely offline.

CryptoCloaks is the official American reseller for the Seedor Safe. Ships next day from Colorado. Bitcoin accepted.

Jameson Lopp Approved ✓

Jameson Lopp — Bitcoin security researcher and creator of the most comprehensive seed storage stress test ever conducted — reviewed the Seedor Safe and specifically praised it for solving the critical flaw of letter-tile systems.

His conclusion: in a multi-part backup, one seed word with its corresponding numbering should be recorded per element. That’s exactly how the Seedor Safe works. One word per disc, numbered in sequence, locked inside a tamper-evident capsule.

When the most rigorous Bitcoin security researcher on the planet endorses your backup method, that’s not marketing copy. That’s the answer to “which one should I buy?”

What’s Included in the Seedor Safe Starter Set

• 1x Seedor Safe capsule (316L stainless steel, sealed)
• Blank 316L stainless steel discs — enough for a full 12 or 24-word BIP39 seed
• Full set of letter stamps
• Hammer
• Tamper-evident numbered seal stickers
• Setup instructions

Everything you need is in the box. No additional tools, no additional purchases. Open it, stamp your seed, seal it, store it.

Compatible with: BIP39 12 and 24-word seeds, Shamir Backup (SLIP39), BIP32 root keys, WIF private keys, and Monero mnemonic seeds. Works with every hardware wallet — Coldcard, Trezor, Ledger, Jade, Foundation Passport, and all others.

How to Set Up Your Seedor Safe

Setup takes 20–30 minutes. Here’s the full process:

1. Prepare your discs — take one blank disc for each word in your seed phrase
2. Stamp each word — use the included letter stamps and hammer to stamp each seed word onto its disc. Work on a hard surface.
3. Stamp the position number — stamp the word’s sequence number (1, 2, 3…) on each disc so you can reconstruct the order if they’re ever separated
4. Load the capsule — insert discs in order into the stainless steel capsule
5. Seal it — apply the tamper-evident numbered sticker. Now you’ll know immediately if anyone has accessed your backup.
6. Store it — somewhere you’ll find it and somewhere fire or flood won’t. Safe deposit box, fireproof safe, buried container.

Done. Your Bitcoin seed is now backed up in a form that will outlast you, your house, and most catastrophic events.

Fire, Flood & Corrosion Resistance

316L stainless steel is marine-grade. It’s used in surgical instruments, boat hardware, and offshore oil platforms. Here’s what it survives:

The capsule design also solves the critical flaw of tile/letter systems: your seed words can’t scatter. If someone finds it, they see a sealed capsule with a numbered tamper sticker — not a pile of loose tiles they can photograph in 10 seconds.

Seedor Safe vs Other Bitcoin Seed Backups

There are three real categories of metal seed backup: stamping plates, letter tiles, and capsule systems. Here’s the honest comparison:

The Seedor Safe is the only capsule system with full tamper evidence and zero scatter risk at the same time. You pay more than a Blockmit Jig — but the Blockmit is a DIY washer system. The Seedor is a purpose-built, engineered backup solution from Germany with an expert endorsement.

If you want the best: Seedor Safe. If you want the cheapest steel backup: Blockmit Jig — $4.99. Both are in stock. We sell both.

FAQ

Q: Do I need any other tools besides what’s in the box?
A: No. The kit includes the hammer, letter stamps, discs, capsule, and stickers. You need a hard surface to stamp on (concrete floor, stone countertop, anvil). That’s it.

Q: How hard is it to stamp the letters?
A: One firm strike per letter. It takes about 20-30 minutes for a full 24-word seed. No special skill required. If you can swing a hammer, you can do this.

Q: What if I make a mistake stamping?
A: Discs are not reversible — stamped impressions are permanent. Take your time, work letter by letter, and double-check each word before stamping. The kit includes extra blank discs for mistakes.

Q: Can I use this for Shamir Secret Sharing (SLIP39)?
A: Yes. The Seedor Safe supports SLIP39 multi-part backup, BIP32 root keys, WIF private keys, and Monero seeds in addition to standard BIP39.

Q: Is it obvious what this is if someone finds it?
A: It looks like a sealed metal capsule. It’s not labeled. A tamper-evident sticker shows if it’s been opened. Nobody who finds it will know what’s inside without opening it — and they’ll know you’ll know if they did.

Q: How does this compare to the Blockmit Jig you also sell?
A: Totally different tier. The Blockmit Jig ($4.99) is a DIY stamping tool for washers — budget-friendly, effective, zero tamper evidence. The Seedor Safe is an engineered, purpose-built capsule system with Jameson Lopp’s endorsement. Both work. The Seedor is better. The Blockmit is cheaper.

Q: Do you accept Bitcoin?
A: Always. We’re bitcoin-native. Pay in sats, keep it sovereign.

The Seedor Bitcoin B: A Precision Bitcoin Metal Stamp for Serious Cold Storage

Most seed backup tools are sold by people who have never secured a wallet. This bitcoin metal stamp is different: built by bitcoiners, specced openly, and designed to work with the Seedor holder jig that keeps every strike vertical and every impression clean.

What Is the Seedor Bitcoin B: Your Bitcoin Metal Stamp for Cold Storage

The Seedor Bitcoin B is a 6 x 6 x 60 mm punch tool machined from drawn 40CR tool steel. It carries the Bitcoin B logo at a 3.5 mm font height. CryptoCloaks sized it specifically for the Seedor alignment system, which means the 6 mm shank fits the holder channel and every strike lands at 90 degrees to the backup surface.

A bitcoin metal stamp needs to do one thing well: transfer a clean, readable impression to your backup surface without slipping, drifting, or leaving a ghost mark. The Seedor Bitcoin B does exactly that. The 40CR steel is hard enough to mark stainless plates, leather, and plastics without deforming the tip, and tough enough to take repeated hammer blows without losing geometry.

This is not a generic crypto tool with an unverified steel spec and a coin logo. It is a Bitcoin-specific stamp, built to Bitcoin standards, sold by a shop that has been in the space since 2017. If you are building a cold-storage backup meant to last decades, this is the mark that belongs on it.

Why CryptoCloaks

CryptoCloaks has been in the Bitcoin space since 2017. Ricky personally picks, prints, and ships every order from his shop in America. That accountability matters when you are buying a tool you will use to protect generational wealth. There is no warehouse, no dropship chain, no anonymous marketplace seller behind this bitcoin metal stamp.

The stamp ships as part of a complete ecosystem. The Seedor stamp holder for vertical alignment keeps every punch perpendicular to the surface during a strike. Reddit threads on DIY metal stamping consistently name misaligned strikes as the top failure mode. A tilted stamp leaves a partial, unreadable impression. The holder eliminates that variable before it becomes a problem.

Additionally, CryptoCloaks publishes its specs openly. You know the steel grade. You know the font height. You know the shank dimensions. Generic marketplace listings cannot say the same. That transparency is a direct expression of the Bitcoin ethos: verify, do not trust.

Bitcoin Metal Stamp Specs and Compatibility

• Dimensions: 6 x 6 x 60 mm
• Font height: 3.5 mm
• Material: Drawn 40CR tool steel
• Weight: 3 oz
• Compatible surfaces: Metal plates, leather, plastics
• Compatible jig: Seedor holder system
• SKU: CC-SD-SEEDBITCB

Steel grade matters more than most buyers realize when selecting a bitcoin metal stamp. Jameson Lopp’s metal Bitcoin seed storage stress test validates drawn tool steel in the 40CR hardness range as capable of leaving legible impressions in stainless steel plates under severe fire, crush, and corrosion conditions. A soft stamp deforms at the tip. A brittle stamp chips. Drawn 40CR holds its geometry through thousands of strikes, keeping the Bitcoin B crisp on every backup you make.

The 3.5 mm font height fits standard seed plate grids without crowding adjacent characters. The 60 mm handle provides a controlled grip surface during a hammer strike. At 3 oz, this bitcoin metal stamp is light enough for precise positioning and solid enough to feel intentional in hand.

How It Compares

Frequently Asked Questions

Can I use this stamp to punch my Bitcoin seed phrase into a metal plate?

The Seedor Bitcoin B is a bitcoin metal stamp designed to mark the Bitcoin B logo, not individual BIP39 seed words. For a complete seed phrase backup, you pair this stamp with a set of letter and number punches sized to the Seedor grid. The Bitcoin B stamp serves as a clear identifier on your backup plate, marking it as a Bitcoin wallet backup rather than a generic document. That distinction matters in an emergency, when someone else may need to locate and use your backup quickly. The 40CR steel punches cleanly into standard stainless steel plates, titanium sheets, and aluminum backups at the thicknesses most cold-storage products use. Plan one deliberate strike per surface position and use the Seedor holder to keep every mark aligned.

What surface should I stamp on to get the cleanest impression?

This bitcoin metal stamp is compatible with metal plates, leather, and plastics. For long-term seed backups, stainless steel or titanium plates produce the most durable and legible impressions. Place a firm, flat backing under your plate before striking. A single deliberate hammer blow at full arm weight gives cleaner results than a series of lighter taps. Avoid any surface with flex or give beneath the plate, because movement mid-strike causes the stamp to drag and leaves a partial impression. For practice runs before committing to your real backup plate, use a scrap piece of aluminum or a leather offcut. Both take clean marks at moderate strike force, allowing you to dial in your technique without risking your actual backup material.

Does this stamp work with the Seedor alignment holder / jig?

Yes. CryptoCloaks designed this bitcoin metal stamp specifically for the Seedor holder system. The 6 x 6 mm shank profile fits the Seedor jig channel, which holds the stamp at exactly 90 degrees to the backup surface during a strike. That vertical alignment is the single most important factor in getting a clean, full-depth impression. Without a holder, even experienced stampers tilt the punch slightly on impact, leaving a partial mark on one edge. The Seedor holder removes that variable entirely. If you are serious about building a readable, durable seed backup, pairing this stamp with the Seedor holder is the correct approach. It is not an optional upgrade, it is the system working as designed.

Add the Seedor Bitcoin B to your cold-storage toolkit today. It is the bitcoin metal stamp built with published steel specs, a jig-compatible design, and nearly a decade of Bitcoin-native community trust behind every order. Bitcoin accepted. Made in America. Ships in 2-3 business days.
