The Swiss Tool Of Crypto

Crafted from extremely robust aerospace-grade titanium, the new Hodlr One provides a permanent backup for your secret recovery phrase in long-term cold storage.

The titanium, etched and enhanced with red inlay, improves readability and punching accuracy, making it a significantly more reliable option than other titanium plates for precise marking and recovery of your master seed.

Physical Peace Of Mind

Fireproof up to 1,650°C (3,000°F), Hodlr One is designed to withstand any physical threat, from house fires and flooding to extreme shocks or impacts. As opposed to standard solutions, your recovery phrase is indelibly punched into the titanium, negating the risk of accidental deletion or loss.

Fusing robustness with ergonomics, the Hodlr One stands as the most compact and lightweight numerical metal seed phrase backup on the market. It can be easily concealed, providing an additional layer of security to your safety net.

As fully tested and highlighted in the blogs of @econoalchemist and @bitcoinmagazine.

Your Keys, Your Control

Designed as a self-custody DIY tool, the Hodlr One eliminates the need for any third-party involvement in engraving, storing, or recovering your seed.

Primed for permanent storage and protection, the Hodlr One can accommodate either 2x 12 words or 1x 24 words seed phrases. It utilizes numerical seed storage encoding, offering both compactness and an additional cipher layer.

Effortlessly engrave your seed in metal using BIP39 or SLIP39, the open-source industry-standard numerical conversion systems. Their wordlists are designed such that seed words can always be identified as 4-digit numbers, ensuring a consistent, reliable recovery method.

Complete Security Toolkit

The Hodlr One arrives complete with an automatic center punch for easy and permanent engraving, outstripping small tiles and hammers in terms of both security and punching ease.

Coupled with uniquely numbered tamper-evident security seals, your backup remains safe, secure, and under your control at all times.

The included simplified step-by-step guided protocol makes the entire process easier, comfortable, and, most importantly, error-free.
Maximum resilience

Anti-Theft Protection

Implementing 2-of-3 Split or Shamir Secret backup solutions is an optimal strategy for dispersing your self-custody crypto assets across various locations. Even if a share is lost or stolen, you are still safeguarded, and recovery remains possible, offering an effective shield against loss and theft.

Hodlr One Multi-Packs excel in Anti-Theft and Anti-Loss security, featuring clear engraving areas for multiple backup identifications and multi-share tracking, up to 5 shares.

Very Professional Backup

Package comes with 2 magnetic boxes that look & feel super pristine.
Magnet is very strong it holds up facing flat on any metal surface, but facing sideways it starts slowly to slide down which isn't a big deal unless you plan to slide it vertical in between something.


Hodlr Disks Classic

Big Recommendation

The packaging is very nice and the HODLR is really high quality.
The centerpunsher works well, but there is also a thing with which you can hammer the 'holes' manually. This i liked even more.
I also really appreciate the tamperproof stickers and the gratis bitcoin stickers.

So i really recommend the HODLR!!
