How to use your metal backup plate:
Materials Required
- Your seed phrase (preferably written down securely on paper).
- An SX6 steel backup plate.
- A marker pen.
- A centre punch (automatic preferred).
Step-by-Step Instructions
- Prepare Your Materials
- Gather your seed phrase, the SX6 steel backup plate, a marker pen, and the centre punch.
- Mark the Plate
- For each word in your seed phrase, use the marker pen to mark the first four letters of the word in the corresponding column on the plate.
- For example, for the first word “super”:
- Mark “1. S” for the first letter.
- Mark “2. U” for the second letter.
- Mark “3. P” for the third letter.
- Mark “4. E” for the fourth letter.
- Repeat this process for all words in your seed phrase, flipping the plate over for words 13 – 24
- Verify Your Markings
- Carefully review the marked letters to ensure they correspond correctly to your seed phrase.
- Double-check your work by cross-referencing with your written seed phrase.
- Optional: Test your backup by restoring a new wallet using your seed phrase to confirm accuracy.
- Engrave the Plate
- Using the centre punch, carefully punch the centre of each marked letter into the metal plate.
- Ensure that the punches are clear and legible.
- If desired, engrave or scratch a note in the designated notes area of the plate using the centre punch.
- Secure Your Backup
- Place the engraved plate into a paper envelope.
- Seal the envelope within a tamper-evident bag.
- Record the unique number on the tamper-evident bag and store this information in a safe location. This number will help verify that the bag has not been tampered with.
- Store Safely
- Store the backup in a secure location, such as a fireproof safe or a lockbox.
- Avoid keeping it in less secure places like a sock drawer.
