FAQ for Black Seed Ink's Steel Wallets

  • Practical and Affordable Steel Solutions

    While titanium solutions are available, they are often overkill and come at a high expense. Black Seed Ink's steel wallets, combined with our easy-to-use engraving tools, offer similar levels of protection at a more affordable price. Our steel wallets are more flexible than punching or chicklet methods, providing a straightforward and effective way to secure your seed phrases and other critical data.

    HODL and Secure Your Investments

    Most early adopters of digital currency are in a HODL (Hold On for Dear Life) position and serve as gatekeepers to their investments. This makes it essential to safeguard your seed phrase against potential threats. Unlike easily destructible paper, our steel wallet provides a durable, fireproof, and waterproof solution for storing your seed phrase.

    Tested for Extreme Conditions

    Our steel plates have passed the rigorous Jameson Lopp's Stress Test, receiving a triple-A rating after enduring a heat test at 2000 degrees Fahrenheit for 10 minutes, a shock test, a three-hour corrosion test using muriatic acid, and a crush test with a 20-ton hydraulic press. This ensures that our product can withstand the most extreme conditions.

    Trusted Worldwide and Patent-Pending

    Trusted by thousands of investors in over 70 countries, Black Seed Ink is the only company with patent-pending steel plate designs that cover all security data surrounding crypto investments. While most companies stop at seed phrases, we believe that all access data to your crypto investments should be protected in cold storage and disconnected from the internet. This includes exchange log-in data, master passwords, passphrases, and of course, the seed phrase.

    Commitment to Excellence and Innovation

    By choosing Black Seed Ink, you are ensuring the highest level of crypto security for your Bitcoin wallet, hardware wallet, and other crypto wallets. Our commitment to excellence and innovation makes us the best solution on the market for protecting your digital assets.

  • A crypto seed phrase wallet is a durable storage solution designed to securely store the seed phrases used to recover access to your crypto wallets. Unlike easily destructible paper, Black Seed Ink's steel wallets provide fireproof and waterproof protection for your seed phrases. This ensures that you can restore access to your Bitcoin and crypto hardware wallets such as Ledger, Trezor, MetMask and other cold and hot wallets, even if your original hardware is lost or damaged. By keeping your seed phrases safe, our metal wallets offer the ultimate security for your digital assets.

  • Black Seed Ink's crypto exchange data wallet allows you to securely store your exchange log-in data offline in cold storage, disconnected from the internet. This ensures your exchange accounts are safe from online threats, fire, and water damage. As the first and only cold storage company offering a steel wallet for exchange data, we provide the best crypto security available.

  • Our Master Password Wallet is designed for users of password managers like Bitwarden, 1Password, and LastPass. It allows you to store your master passwords offline in a secure, steel wallet, protecting them from online threats and physical damage. This cold wallet solution ensures that your critical access information remains safe, providing peace of mind for your digital security needs.

    The best password keepers do not allow for a "backdoor" to reset a lost master password. If you lose your master password, developers can't reset it, eliminating a significant point of failure. To maximize security, master passwords should never be photographed, stored on digital devices, or written on paper, which is vulnerable to damage and loss. By storing your master password offline in our robust steel wallet, you ensure the highest level of protection for your digital assets and password manager.

  • The Passphrase Wallet by Black Seed Ink is specifically designed for storing your passphrase, also known as the 25th seed phrase, providing an additional layer of security for your 12 or 24-word seed phrases. This steel crypto wallet ensures your blockchain access data is securely stored offline, away from potential online threats, fire, and water damage.

    What sets our Passphrase Wallet apart is its ample space for etching a word, phrase, or sentence, along with the name of the wallet it is assigned to. This design feature allows you to keep your critical information organized and easily identifiable, enhancing the overall security of your crypto wallets, including popular cold wallets like Trezor, Ledger, and Ellipal, as well as hot wallets like MetaMask and Coinbase Wallet. By using Black Seed Ink’s Passphrase Wallet, you ensure that your most sensitive blockchain access data is protected with the highest level of security.

  • Steel wallets offer superior protection for your digital assets compared to traditional storage methods. Black Seed Ink's metal wallets are fireproof, waterproof, and durable, ensuring your seed phrases, master passwords, and exchange log-in data remain safe. Our wallets are perfect for crypto cold storage, providing unmatched crypto security.

    Etching vs. Punch Set

    Unlike punch sets, which require a numeric punch set and hammer, etching into steel is a quiet and efficient process. Punch sets can be noisy, warp the material during use, and are limited to storing only seed phrases. They are not suitable for storing other types of data, such as exchange log-in information, master passwords, or passphrases. Our etching method ensures that all your critical data can be securely stored without the drawbacks of a punch set.

    Homemade Washer Sets and Chicklets

    Other methods of backing up seed phrases, like homemade washer sets or chicklets, are also inferior. These methods can scatter letters or words during crush tests, compromising the integrity of your backup. In contrast, Black Seed Ink's steel wallets provide a robust and reliable solution that withstands extreme conditions, ensuring your data remains intact and easily readable.

    Paper Backups

    Paper backups are another common method for storing seed phrases, but they are easily destructible and vulnerable to fire, water, and physical damage. Over time, paper can degrade, making the seed phrases unreadable. In contrast, our steel wallets are designed to last a lifetime, protecting your critical data from environmental hazards.

    Digital Storage

    Storing seed phrases digitally on smartphones, computers, or cloud services poses significant security risks. These devices are susceptible to hacking, malware, and data breaches. By keeping your seed phrases offline in a steel wallet, you eliminate the risk of online threats and ensure your information remains secure.

    Plastic Cards

    Some users opt for plastic cards to store their seed phrases. While more durable than paper, plastic cards can still be damaged by fire, water, and physical stress. They are also not as durable or secure as steel wallets. Black Seed Ink's steel wallets offer superior protection against environmental and physical threats.

    By choosing Black Seed Ink's steel wallets, you are investing in a secure, versatile, and durable storage solution that protects your digital assets from a wide range of threats. Our wallets are designed to accommodate various types of critical data, making them the ideal choice for comprehensive crypto security.
