The Cryptosteel Cassette Duo package serves as an optimal strategy to enhance security by offering dual offline cold storage backup systems.

The Cryptosteel Cassette was the pioneering product that paved the way for the metal-based offline wallet sector.

Included in this set are two compact stainless steel modules, engineered to safely house user-selected alphanumeric entries without requiring any specialized equipment or external parties. Each unit is accompanied by its own collection of double-sided engraved stainless steel tiles.

Encryption keys and passcodes are constructed by hand, utilizing a semi-random assortment of characters provided. Users have the capability to safeguard up to 96 characters, equivalent to 24 mnemonic phrases, ensuring both the rapid storage and utmost protection of their data.

When a particular sequence is set within the Cassette, it inherently attains a state of enduring offline preservation, withstanding various physical threats like fire, water damage, corrosive environments, electrical disturbances, and unforeseen impacts.

Optimised for Recovery Seed Phrases

Your 12-24 recovery seed phrase adheres to the Bitcoin Improvement Proposal 39, or BIP39, enabling the use of a language based mnemonic for backup should your wallet be misplaced or becomes unusable.

These mnemonic words are derived from a predefined set of 2,048 English terms. Despite varied word lengths, the initial four characters distinctively pinpoint each word. This includes instances with three-letter words where the fourth tile remains vacant. Hence, with four tiles, you can uniquely identify the exact phrase.

The Cryptosteel Mnemonic accommodates precisely 96 characters, aligning with the storage requirements of a 24-word list under the BIP39 protocol. Every Mnemonic tile kit showcases an optimal character distribution, meticulously designed for peak functionality and user-friendliness, and they are semi-randomized to bolster security measures.
