How are Ballet wallet passphrases and encrypted private keys are matched correctly during the manufacturing process?

Ballet’s manufacturing process involves the use of serial numbers to match the corresponding encrypted private key, passphrase, and cryptocurrency address. You can see the three matching serial numbers on the right side of the Ballet wallet: one on the steel wallet card, one on the cryptocurrency address QR code sticker, and one on the yellow encrypted private key sticker below. Here’s how the serial numbers are used in the manufacturing process:

  1. The first step in the two-factor key generation process is generating a BIP38 wallet passphrase and its corresponding BIP38 intermediate code. These two pieces of information are linked together by a serial number.
  2. The intermediate code and the serial number are electronically transmitted to the secure manufacturing facility where the encrypted private key is generated. 
  3. The encrypted private key and its associated cryptocurrency address are generated from the intermediate code.
  4. The encrypted private key and cryptocurrency address are printed on tamper-evident QR code stickers along with the serial number.
  5. The QR code stickers are shipped back to the first manufacturing facility.
  6. The QR code stickers are affixed to a steel wallet card.
  7. The BIP38 wallet passphrase, which was labeled with a serial number in the first step of the process, is laser-etched onto the steel wallet card with the corresponding QR code stickers.
  8. Our rigorous quality control process ensures that all three serial numbers on the finished product match.
