Description

Seed Keys’ 2-Pack Backup Keys is a bundle that includes two Backup Keys, the essential version of Single-Sig Backup Key Set. It excludes the letter punch set for those who already have one.

Seed Keys’ Single-Sig Backup Key Set is a robust and reliable solution for autonomous offline storage of your Bitcoin recovery phrase. It stores up to 24 words from the BIP39, BIP44, or SLIP39 list. To use, simply stamp the first four letters of each word of your seed phrase onto the corresponding key.

The 14 keys are precision-cut in a plate made from 1.5 mm thick 316L stainless steel that is resistant to fire, water, and corrosion. Each key is laser engraved with a unique number on both sides (recto-verso) for easy identification and organization.

A stamping jig ensures accurate and consistent letter alignment when punching your seed phrase.

The key set features a tamper-evident design, with a sturdy split key ring holding the keys together and nylon cable ties securing them in place, providing a clear indication if someone has attempted to access the contents. Additionally, it is packaged in a Mylar bag that can be heat-sealed for an additional tamper-proof layer.

Note: A letter punch set is not included. You will need to use your own or purchase one separately.

Features

Here are a few of the features that make Backup Keys the perfect solution for your Bitcoin storage needs:

Durable by Design

A long-lasting medium and robust construction, combined with a permanent recording method, protect your seed phrase from wear and tear and environmental damage, providing peace of mind.

Seamless Wallet Integration

Compatibility with widely adopted standards (BIP39, BIP44, SLIP39), ensures a native integration with most hardware and software wallets, and cryptocurrencies, for a hassle-free experience.

Flexible and Private

A compact and versatile design enables easy concealment, and discreet portability, while allowing for proper disposal of your old seed phrase, safeguarding your transaction history.

Simple and Intuitive

A straightforward design, combined with the use of 4-letter word segments, ensures an easy and efficient stamping process and enables a quick and effortless recovery of your seed phrase.

Tamper-Evident Security

Tamper-evident seals provide clear indication of any attempted access, giving you confidence that your seed phrase remains untouched, and allowing you to timely respond to potential breaches.

Offline and Secure

A cold storage method, completely disconnected from the internet, eliminates the risk of hacking and unauthorized access, ensuring the security and integrity of your seed words.

Getting Started with Your Seed Keys

To create your secure seed phrase backup, you’ll need:

  • Your Seed Keys plate
  • The orange stamping jig
  • The letter punch set (not included)
  • A hammer (not included)

The process can take around 15–20 minutes to complete. However, it’s essential to focus on accuracy rather than speed.

Stamping your keys ensures complete confidentiality and control over your seed phrase.

FAQ

Below are answers to some frequently asked questions about Seed Keys:

Buying a bundle allows you to establish proper security redundancy. Best practices recommend storing copies of your recovery phrase in separate physical locations (such as a home safe and an off-site deposit box), protecting you against localized fire, flood, or loss.

Multiple units are also essential if you manage several wallets or configure multi-signature setups.

Finally, multi-packs offer significant savings per unit, making them the most cost-effective way to secure all your seed phrases or equip family members and friends with resilient cold storage.
Yes. Backup Keys provide durable, offline storage for the resulting seeds and shares. Each unit offers dedicated space to stamp seed words and identifiers.

Whether you configure a multi-signature quorum, Shamir’s Secret Sharing, or a manual split like Penlock, multi-packs allow you to record each key or share on its own separate plate and distribute them across different physical locations to eliminate any single point of failure.
If you make a minor mistake that doesn't compromise the legibility of the word, you should try to re-stamp the correct letter or word. However, if the mistake makes the word illegible or potentially creates confusion with other words of your word list, you should purchase a new metal seed phrase storage. Unfortunately, individual replacement keys are not for sale.
