Using the printed bip39 English word list, search each word from your mnemonic phrase (seed) that was previously generated by a device, an application or a web service, and note the corresponding number. For example, the corresponding number for the word “olive” is 1234.

You can also use any of the bip39 list language versions – English, Japanese, Korean, Spanish, Chinese (Simplified), Chinese (Traditional), French, Italian. Any of these lists contain 2048 words. KryptoDots backup set can accommodate up to 24 words per plate (12 words per side).

After you converted all your words into numbers, you can proceed with the next step.

See for more information.

Each group of 4 by 10 holes delimits 12 zones, where you will encode the numbers converted in the previous step, from your mnemonic phrase (seed). The numbers can be from 1 digit long to a maximum of 4 digits long, meaning that you can theoretically mark any number from 0 to 9999.

Each zone is named on top with numbers from 1 to 12 (representing one side of the metal plate) respectively /13 to /24 (representing the other side of the metal plate). You can encode up to 24 words on a plate (12 words per side).

The markings from 0 to 9, positioned in the center of the encoder will help you to position the digits for each number correctly. The columns within the zones (4 columns) represent the digit position within the number.

The center top hole is an indicator hole. Through this hole you can mark one of the two sides, so you know which one is 1st or 2nd side. It’s up to you to establish which side to mark.

With the encoder and the metallic base plate firmly attached with the 2 screws and 2 nuts, carefully mark all the numbers on the two sides with a mechanical pencil or a sharp pencil. If you made a mistake just remove the encoder and erase the markings. We recommend marking the leading 0 (zero) when necessary for a more accurate decoding.

We recommend that all operations will be done with the encoder and the metallic base plates fixed in the plastic or MDF case. The spare plate can be used as a counter-punch, thus the marking plate will not deform. The plastic or MDF case is designed to stabilize and fix in place the encoder and the metallic base plate(s). With the encoder and the base plate firmly attached with the 2 screws and 2 nuts, use the included center punch and a hammer to permanently punch the dots you previously marked.
There’s no need to use a wrench to tighten the screws. It’s enough to use only your fingers to tighten the screws and bolts.

Example - how to mark a word = number

  • Let’s use the number 1789 (corresponding to the word ”test”) as the 1st word from your mnemonic phrase, so it will be marked in zone 1.
  • The number 1789 has 4 digits so we will start with the digit 1.
  • Use a pen to mark the dot through the encoder on the far-left column on row 1.
  • On the next column to the right, on row 7 we mark the digit 7.
  • On the next column to the right, on row 8 we mark the digit 8.
  • We move further to the right marking on the next column on row 9, the digit 9 and the last one for this word.

The markings can be done in any order you like, for example starting with the last digit (digit 9) marked on the far-right column in the group and moving to the left. For the rest of the words (numbers) just repeat the process described above by marking the next zone. When you reach the 12th word, unscrew the nuts, flip the plate and tighten the screws and nuts. Follow the same steps for the rest of the words.

Don’t forget to mark one of the sides. Our recommendation is to mark the first one.

12 WORDS example - full side

Word “test” = number 1789 marked as 1st word = zone group 1
Word “plate” = number 1330 marked as 2nd word = zone group 2
Word “punch” = number 1391 marked as 3rd word = zone group 3
Word “zone” = number 2047 marked as 4th word = zone group 4
Word “digital” = number 496 = 0496 marked as 5th word = zone group 5
Word “asset” = number 110 = 0110 marked as 6th word = zone group 6
Word “advance” = number 32 = 0032 marked as 7th word = zone group 7
Word “gadget” = number 758 = 0758 marked as 8th word = zone group 8
Word “smart” = number 1637 marked as 9th word = zone group 9
Word “choice” = number 322 = 0322 marked as 10th word = zone group 10
Word “easy” = number 559 = 0559 marked as 11th word = zone group 11
Word “life” = number 1035 marked as 12th word = zone group 12
