Trezor has launched a solution for backing up wallet passwords called Trezor Keep Metal. Trezor Keep Metal aims to protect users' recovery seeds and comes in two options: a standard 12-word backup for $99 and a 20-word Shamir-compatible Trezor Safe 3 backup for $249. Keep Metal is designed to ensure that recovery seeds stored on paper are safe under any conditions, thanks to its corrosion-resistant exterior and waterproof seal. The company stated in a statement that these products are now available for pre-order and will be shipped to the public in mid-November.
