Q & A
What is the primary purpose of a cold wallet?
-A cold wallet is designed to store cryptocurrencies offline, providing enhanced security against online threats and unauthorized access.
Why are seed phrases considered essential for cold wallets?
-Seed phrases are crucial for wallet recovery, allowing users to restore their wallets if they lose access. They are still the preferred recovery method for most wallets.
What is the difference between a 12-word and a 24-word seed phrase?
-A 24-word seed phrase is longer and technically more secure than a 12-word seed phrase, as it has more combinations, making it harder to guess.
What is a passphrase and why is it important?
-A passphrase is an additional word or phrase added to a seed phrase that creates a hidden wallet. It is vital for securing your wallet, as it prevents access even if someone finds your seed phrase.
How does a secure element chip enhance wallet security?
-A secure element chip isolates and securely stores the wallet's private keys, preventing unauthorized access even in case of a malware attack or physical brute-force attack.
What are the benefits of open source firmware in cold wallets?
-Open source firmware promotes transparency, allowing the community to review and identify vulnerabilities, thereby enhancing overall security.
How does a device-specific PIN protect a cold wallet?
-A device-specific PIN adds an additional layer of security by requiring physical access to the wallet, making it harder for unauthorized users to access your funds.
What is Shamir backup, and why is it beneficial?
-Shamir backup is a method to split a seed phrase into multiple shares, requiring a specific number of those shares to recover the wallet. This adds a layer of security by distributing the risk.
Why is it important to store the seed phrase and passphrase separately?
-Storing them separately minimizes the risk of losing access to your wallet. If both are stored together and compromised, it could lead to total loss of funds.
What additional features does the Keystone 3 Pro offer beyond the essential ones?
-The Keystone 3 Pro offers advanced security features, including biometric authentication, multiple secure element chips, and the ability to manage multiple seed phrases, making it suitable for advanced users.
