Description

Seed Keys’ Multi-Sig Backup Key Set is a bundle that includes one Single-Sig Backup Key Set and two Backup Keys.

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.

This set includes a stamping jig and letter punch set for accurate alignment. You only need a hammer to complete your backup.

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: The letter punch set may vary from the image but meets the same quality standards.

This bundle is ideal for 2-of-3 multi-signature wallets, the most popular setup for reliable Bitcoin storage. The different-colored cable ties, with a writing area, make it simple to organize and manage your seed phrases.

FAQ

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

You should use a 2-of-3 multi-signature wallet to reduce the risk of theft and loss of single-signature wallets. A single compromised device or lost seed phrase can result in the loss of your entire Bitcoin stack.

The 2-of-3 multi-sig custody model provides an additional layer of security, as an attacker would need to compromise two separate devices or obtain two separate seed phrases to access your funds.

Plus, if one seed phrase is lost, damaged, or compromised, you can still recover and access your funds with a 2-of-3 setup.

Yes, you can use each Single-Sig Backup Key Set with wallets that support the BIP39, BIP44, and SLIP39 standards, such as Trezor, Coldcard, and Bitbox, among other brands. Since the backup is a physical record of your seed phrase, you can use it to restore your funds on any compatible wallet.

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.
