Secure Your Crypto A Step-by-Step Leather Wallet browser extension Wallet Recovery Phrase Setup
Immediately after generating your mnemonic seed, transcribe the sequence of words onto the provided steel plates using the included stylus. Paper is a temporary, unacceptable medium for this purpose; ink fades and the material is vulnerable to fire and water. The alloy plates resist temperatures exceeding 1500°F and will not corrode, ensuring the sequence remains legible for decades.
Never digitize this collection of words. Prohibit any action involving a keyboard, smartphone camera, or cloud storage. The objective is to create a purely physical artifact, isolated from networks and potential malware. A keylogger or compromised device can intercept the data in milliseconds, nullifying the protection of the physical object.
Verify the transcription by performing a full restoration of the sequence into a temporary, isolated software container before transferring any assets. This single action confirms both the accuracy of your engraving and your functional understanding of the restoration process. Store the finalized plates in separate, geographically distinct locations, such as a bank vault and a personal safe, to mitigate localized physical risks.
Q&A:
Is it really necessary to write down my recovery phrase on paper? Can’t I just save it as a file on my computer?
Storing your recovery phrase as a digital file is strongly discouraged. Computers and phones are frequently connected to the internet, making them vulnerable to malware, hacking, or accidental exposure through cloud backups. A paper copy, kept physically secure, removes this online threat. While paper can be damaged, this risk is managed by using durable materials and having multiple copies in separate locations. The core principle is air-gapping: isolating your most sensitive secret from any networked device.
What’s the best pen to use for writing a seed phrase on metal?
For metal plates, a fine-point permanent marker or an engraving tool is common, but these can fade or corrode. A more reliable method is using a set of metal letter stamps. You hammer the characters directly into the plate, creating a permanent, physical impression. This withstands fire, water, and time far better than ink. If you choose to write, select a pen with an archival-quality, acid-free ink designed for metal surfaces, but understand that stamped metal offers superior permanence.
I’ve heard about “shamir’s secret sharing.” Is splitting my phrase into parts a good idea for security?
Splitting your phrase can increase security, but how you do it matters. Simply cutting a 12-word phrase in half and storing two 6-word pieces is dangerous. If someone finds one half, they only need to brute-force the other, which is computationally feasible. Proper Shamir’s Secret Sharing (SSS) is a cryptographic method that creates multiple “shares.” You can define a threshold (e.g., 3 out of 5 shares) required to reconstruct the phrase. This is robust, but it requires a trusted SSS tool and careful management of the shares. For most, storing complete, duplicate copies in secure physical locations is a simpler, less error-prone strategy.
My wallet generated a 24-word phrase, but my friend’s only has 12. Which is more secure?
Both are extremely secure against brute-force attacks. A 12-word phrase has 128 bits of entropy; a 24-word phrase has 256 bits. The number of possible combinations for a 12-word phrase is astronomically large (2^128), making a random guess attack impossible with current technology. The 24-word phrase offers a larger safety margin for future advances in computing and theoretical vulnerabilities in the underlying cryptographic algorithm. However, the practical difference for a user today is minimal. The greater risk is always in how the phrase is stored and kept secret, not the word count. A well-protected 12-word phrase is far safer than a poorly managed 24-word one.
