    Double check everything is correct.


    Step 3:
    Convert your seedphrase into numbers.

    By comparing each word of your seedphrase with the BIP39 standard, you can convert them into a unique number between 1 and 2048. You need to do this conversion for each word of your seedphrase and write the numbers in the conversion sheet in the same order as your original seedphrase.

    A paper BIP39 English wordlist is included in the package, or you can also refer to the original source.

    WARNING: Do not input your seedphrase digitally. Please do this step 100% offline with pen and paper. Do not use tools like "CTRL+F" to convert your seed.

    Step 4:

    Step 5: Punch the numbers into the plate.

    Proceed to punch the numbers by giving one single good hit into the plate with your hammer using the center punch tool.

    Take your time to punch the dots in the correct cell and position, this is the most tedious part. You need to stay focused to avoid hurting your fingers with the hammer and to punch everything in place.

    Tip: You may use a marker to "pre-fill" the cells you have to punch, this may help as a visual guide and reduce the chance of a mistake.

    Step 6: Destroy the conversion sheet.

    After you have punched the seed unto the steel, there's really no need to keep the conversion sheet so you can get rid of it by burning it 🔥.


    Step 7:
    Put your backup in a safe spot.

    Once you've finished the entire process, put your steel backup in a safe spot only you know.


    🎉 Done!
