How to Use HeirTAB L1

imKey HeirTAB L1 is a new tool for securing mnemonic phrases. Made entirely from 304 stainless steel, it's waterproof, fireproof, and corrosion-resistant. It's easy to use and affordable, while providing a solution to securely store the mnemonics phrases by complete offline operation, eliminating accidental and potential online risks.

What's in the box?

  • 2 x HeirTAB L1
  • 1 x Punching Tool
  • 1 x Positioning Plate
  • 1 x Hanging Strap
  • 2 x Mnemonic Phrase Card
  • 1 x Instruction Card

After verifying that all the accessories in the packaging box are complete, you may proceed with stamping the engraving.

Instructions for Use

  1. When using the imKey Pro hardware wallet for the first time, create a wallet and transcribe the backup mnemonic phrase onto the mnemonic phrase card.

    According to the BIP39 specification, the first 4 letters of each word are sufficient to uniquely determine the mnemonic phrase. Therefore, when stamping, you only need to stamp the first 4 letters of each word. For example, if you want to stamp the word 'abandon,' you only need to stamp 'aban.' (For words with only 3 letters, you can simply leave the fourth position blank.)


  2. Stamp the engraving on the HeirTAB L1 in the order of the mnemonic words. Both sides of the stamping plate can be used, and one stamping plate can backup 12 mnemonic words.
    The positioning plate helps you position the holes, making the backup operation simpler.

  3. You can also make wallet identification marks on the positioning plate, allowing you to thread the hanging strap through it and connect it with HeirTAB L1. This can serve as a marker for identifying the wallet corresponding to this mnemonic phrase, facilitating convenient storage.

  4. After completing the stamping, store imKey HeirTAB L1 in a secure place to prevent it from being peeked or lost.

    A reminder:
    If you have applied any encryption to the mnemonic backup, be sure to record your encryption rules, and store them separately from the wallet in different locations for safekeeping.
