The BIP-39 standard, or “Bitcoin Improvement Proposal 39,” is a widely accepted system for managing seed phrase, which are easy-to-understand sets of words used for cryptocurrency wallet backup and recovery. BIP-39 ensures that these phrases are both user-friendly and secure.
BIP-39 defines a standard format for creating mnemonic phrases, typically consisting of 12, 18, or 24 words. These phrases represent a binary cryptographic seed (a long string of 0’s and 1’s) used to generate private keys and their corresponding public keys.
If you lose access to your wallet, you can recover it by entering the mnemonic phrase into a compatible wallet application. The app uses the phrase to recreate the keys, restoring access to your funds.
It is essential to protect your mnemonic phrase. Anyone with it can regenerate keys and access your funds. Store it securely and confidentially with VaultKi’s seed phrase storage solution, the first physical blockchain designed for safety.
It’s a secure method for storing your cryptocurrency wallet’s seed phrase by stamping/engraving it onto stainless steel, a durable material ensuring long-term protection against loss, damage, hack or theft.
VaultKi’s patent-pending design stands as a unique representation of blockchain technology, which is renowned for its security features, and serves as the foundation for cryptocurrencies like Bitcoin.
Stainless steel is resistant to corrosion, fire, water, and physical damage, making it an ideal material for preserving sensitive information like seed phrases.
VaultKi’s design team has been working on developing the most innovative seed phrase storage solution in the market. On top of being resistant to physical damage, VaultKi’s offering is also tackling the most important threat: Theft!
It’s highly secure as it’s not susceptible to hacking or digital theft and is physically robust. Also, when considering inheritance, it is much more suitable and accessible without being reliant on complex digital systems, making it a dependable choice for preserving your assets for future generations.
Stainless steel is recyclable, making VaultKi’s products an environmentally responsible choice. Also, our stamping kit and packaging are designed with recyclability in mind. The 3D printed stamping stand utilizes recyclable materials, just like the eco-friendly cardboard used for the box, and the recyclable steel for the letter punch set.
Stainless steel is exceptionally long-lasting, and when cared for properly, it can endure for a lifetime, making it the perfect choice for safeguarding your seed phrase for future generations.
The weight of the VaultKi physical blockchain is quite light at around 80 grams, ensuring durability yet easy handling, transportation and storage.
Currently, we offer a standard innovative and proprietary design, but we’re looking to introduce more designs in the future.
You will only stamp the first 4 letters of each word on your VaultKis as instructed in our instruction manual (More on the stamping process in this link ). These are all you need to accurately recover your seed phrase. No two words from the seed phrase wordlist (BIP-39 standard list available here) share the first 4 letters.
Carefully write down the first 4 letters of each word on the template pages A & B of your instruction manual (link to download the manual here) and follow the process to stamp each letter in the right order. Before permanently stamping any letter, ensure the letter on the punch is oriented in the correct reading direction.
After completing the task, instead of discarding the paper, securely destroy it by burning to guarantee that no one can ever access its content.
Yes, it is designed to resist extreme temperatures, corrosion, and physical damage.
The average melting temperature of the 304-grade stainless steel we use is around 1,400 to 1,450 degrees Celsius (2,550 to 2,650 degrees Fahrenheit), while an average house fire typically ranges between 593 to 649 degrees Celsius (1,100 to 1,200 degrees Fahrenheit).
VaultKi’s design ensures your seed phrase is not immediately visible, offering an additional layer of security. Not only does it keep your physical blockchain safe inside a sturdy metal cover, but its three-dimensional design ensures protection from both prying eyes and cameras. When positioned on a table or desk, at least one side remains concealed at all times.
Once stamped, the phrase is permanent. It is immutable like a digital blockchain thus increasing its reliability. Your words cannot be altered or tampered with, even in the presence of mishaps or accidents. For a new seed phrase, a new VaultKi is required.
Mistakes can be hard to correct. We advise practicing on a sample piece before stamping your actual seed phrase.
If you’ve got just one copy of your seed phrase on one VaultKi set, you’d ideally rely on your hardware or software wallets that save your seed phrase for you (at a risk, but still… they do…). You can then move all your crypto-assets to a new wallet with a fresh seed phrase and save that new seed phrase on new VaultKis.
But we suggest a safer approach. Instead of one copy, go for two copies of your seed phrase. This way you’ll have a pair of each half. If any half is lost, it wouldn’t compromise your access to your own wallet. You can still recover your wallet by putting together the full seed phrase using the remaining parts. It’s like having a backup for your backup, just to be extra safe.
You need a VaultKi especially if you have a hardware wallet like Trezor or Ledger. If you opted for a hardware wallet, it means that you are conscious of the responsibility of keeping your seed phrase offline and safe. Also, it means that you will need to take with you your hardware wallet device wherever you go to be able to confirm any transaction, which increases the risk of losing the device. If lost, no worries, with your VautKi you can reinitiate your wallet on any new hardware device or software wallet and gain access again to your crypto wallet. In other words, the two hardware are complementary not substitutes.
If you want extra safety or share a wallet with other stakeholders, like in a family or a business, you would want to build your multi-sig package by adding as many VaultKi add-ons as needed.
A multi-sig (short for multi-signature) wallet is a type of digital wallet used for storing and managing cryptocurrencies. It requires multiple parties to authorize a transaction before it can be executed. This is different from a standard wallet, which only requires one signature or approval from its owner.
In a multi-sig wallet, there are several keys (like digital signatures or passwords). Each key is held by a different person or entity.
You can set up the wallet so that a transaction needs approval from a certain number of these key holders. For example, if you have a 2-of-3 wallet, any two of the three key holders must approve a transaction for it to go through. You can opt for any m-of-n configuration where you will need any combination of “n” keys out of the “m” outstanding to digitally sign a transaction for it to go through. Also, if one key is lost you would still be able to recover your wallet with any combination of “n” keys

It’s like having a backup for your backup, just to be extra safe.
Like any physical object, it can be lost. We recommend storing each half in different secure and memorable locations. Also, we recommend keeping more than one copy as mentioned in question 8.
If the seed phrase is still legible, it’s safe to use. Otherwise, consider transferring your assets to a new wallet and re-stamping the fresh phrase on a new VaultKi.

Absolutely, it is designed to be user-friendly and precise for those new to metal stamping. Given it requires the use of a hammer, we recommend keeping it away from children and operating it carefully during the stamping process to avoid harming yourself or others and to prevent damage to any furniture or support you may be using.
