What is Cold Storage?

Cold storage refers to keeping your cryptocurrency private keys and access codes entirely offline. By doing so, you eliminate the risk of online attacks and unauthorized access. Cold storage options include hardware wallets, paper wallets, and physical devices that store your crypto assets securely, away from the internet's reach.

Black Seed Ink is the only company in the world that takes cold storage five levels deep. By providing cold storage for not only your seed phrase, but in addition, your exchange data, master password, passphrase and hardware devices, we are proud to protect your investments from every angle.
