The "imKey Safe - Gold Edition" is precision-made from 304-grade stainless steel, with waterproof, fireproof, and corrosion-resistant features, and supports the storage of 2 sets of 12-word mnemonic phrases.
Usage Recommendation:
- Use a screwdriver to unscrew all screws and place the stainless steel letter blocks in each empty slot.
- The letter blocks and screwdriver are both stored in the packaging. Each empty slot can hold up to 4 letter blocks. According to BIP39, the first 4 letters of each mnemonic phrase are unique, so only the first 4 letters are needed to represent a unique mnemonic phrase. If you encounter a mnemonic phrase with 3-letter words, you can flip the letter blocks and place them in the empty slots as placeholders. You can view a list of 2048 mnemonic words here: https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt.
- The letter blocks "b" and "q", "d" and "p", and "n" and "u" in the packaging can be interchanged.
- This product supports both hardware and software wallets that comply with BIP39 and can support up to 96 letter blocks on both sides, corresponding to 12, 18, or 24-word mnemonic phrases.
