How to Protect Your Bitcoin Seed Phrase with The Kiboruto Steel Backup

This guide shows you how to set up a new Samourai wallet on Android and how to secure the seed phrase in a sturdy, stainless-steel backup called The Kiboruto. It was created by @Crazyk_031 & @stackbitme. The Kiboruto can be found at Congratulations on taking self custody of your bitcoin. You need to ensure that your bitcoin is safe and secure from environmental hazards such as fire and flood. Not only is it a good idea to write down your backup information in your notebook, but you might find that it does not feel secure enough when you consider environmental hazards. You are the only one responsible for your bitcoin funds. Bitcoin does not have a 1-800 helpline or charge-back option so you need to make sure you protect your funds. This guide will focus on Samourai Wallet as the Kiboruto was specifically designed for it. Three key pieces of information are required to protect your Samourai Wallet: Seed WordsWhen you create Samourai Wallet you will be given a list with 12 words, sometimes referred to as your seed phrase or “mnemonic phrase”. These 12 words are key information that will allow you to restore your Bitcoin wallet in case you lose it, it is stolen or is damaged beyond repair. You must always save seed words in the same order as your wallet presents them to. Your bitcoin backup could be destroyed if you get one word wrong. Prepare for the worst. Secure your seed words as if they were gold or jewelry. 2. Passphrase. When you generate your Samourai Wallet, you will also need to enter a passphrase. The passphrase you choose is unique and is not generated automatically by Samourai Wallet. Your Samourai Wallet does not know what passphrase was entered. Any passphrase that you enter will also generate a valid wallet. It is up to you to remember the same passphrase that you used when setting up your wallet the first time. A passphrase can be any combination of lower/uppercase letters, numbers, or special characters, unlike seed words which are pre-defined and consist of 2,048 English words. 3. PayNymLast, but not least, is your PayNym. PayNym is your unique name and avatar. It is associated with your wallet. This PayNym can be used to verify that the wallet has been restored. Your PayNym can do more than that. It can display a static code to receive funds, without disclosing any of your transaction history. Your PayNym can be used to connect with other Samourai Wallet users, so you can create collaborative CoinJoin transactions such as StonewallX or Stowaway. Visit for more information. Next, we will show you how to get the three pieces of information from a new Samourai Wallet. The Kiboruto stainless steel backup was specifically designed for your Samourai Wallet. This stainless-steel backup can withstand extreme environmental conditions like a house fire or severe flooding. People often use a pen with paper to write down their seed phrases. You can download the Samourai Wallet Recovery Template here. Your paper backup may not be able to withstand a fire or flood, so you can use both methods to ensure your safety. You should keep in mind that anyone who has access to this information can technically gain access to your bitcoin. Here is a video showing you how to set it up and get the seed words to stamp into your Kiboruto. The wallet version (0.99.96g), used in this video, has been updated to a more recent version with an explanation introduction. The new version will be shown later in the guide, when it will be demonstrated how to recover your seeds words. Stamping the Kiboruto Navigate to your Samourai Wallet homepage and click on the three dots menu in the upper left-hand corner. Select “settings,” then select “wallet,” then choose “show mnemonic.” Your 12 seed words will be displayed in a dialog box. These are the words that you want to stamp in the Kiboruto. To verify your passphrase before stamping, navigate to your Samourai Wallet homepage and click on the three dots menu in the upper right-hand side. Select “settings”, then “troubleshoot,” then select “passphrase/backup testing.” You can then enter your passphrase, and SamouraiWallet will confirm that it is correct. Once you are sure that your passphrase is correct, you can stamp it in Kiboruto. To view your PayNym, navigate to the lower right-hand corner and click the purple PayNym icon. Your PayNym shortname will be displayed below your PayNym avatar. You should use a solid surface to stamp your Kiboruto. To get a crisp stamp, a heavy hammer such as a 4-pound mini sledge is a good choice. The 12 seed words will be stamped in the order they appear on the large Kiboruto plates. Next, you will stamp your passphrase on the small Kiboruto plates and then your PayNym and payNym on that plate. You can keep the two pieces of information separate if you wish. Both the seed words and the passphrase are required to recover your bitcoin in case you lose your wallet. You now have the information you need to restore your Samourai Wallet or recover your bitcoin in the event that your backup is damaged, lost, stolen, or exposed to fire or flooding. It is important to test these backups to ensure that they are recoverable. Although you may not be able to do your own fire test, or have the skills/tools required to do so, here is an example of how the Kiboruto was brought to just below melting point, 1,500° celsius. The Kiboruto secured the necessary information to restore the Samourai Wallet, and regain bitcoin access. The seed phrase can be recovered 100% and most of the etching survived. This section will show you how to restore your Samourai Wallet with only your Kiboruto backup information. Restoring from Kiboruto This means you can use many Bitcoin wallets to recover funds from this backup. If you lose your mobile phone, you can download the Samourai Wallet app again, and then follow these steps using your Kiboruto. After you launch Samourai Wallet you will be able to choose from the recommended options to connect Tor or to your RoninDojo. You will then be able to restore from backup. You will then be able to choose to restore from backup. provides a list of all Bitcoin wallets. Here are the Samourai Wallet derivation paths, for example:Deposit: m/44’84’/0’/2147483647’When restoring a Samourai Wallet on another Samourai Wallet client, you will not need to worry about these derivation paths. This is only relevant if you are restoring across platforms to another wallet. The last considerations are how many copies you want, where you store them, and whether or not you keep the passphrase separate. Each person’s threat model, situation, and circumstances is unique. Therefore, each individual will have to make these decisions for themselves. Keep in mind that an adversary can restore your wallet if it finds your seed words or passphrase.
