Video Instructions

Recording your hardware wallet seed words into the ColdTi couldn’t be simpler and more straight forward.

Depending on your engraving skills or how small your metal punching tools are, you can either record the entire seed word or just the numerical reference to the seed word based on the official BIP 39 seed word list.

Begin by placing the ColdTi plate on a hard surface such as a jeweler’s block to ensure a deep indentation from the number / letter punch.

Once you have confirmed the first word of your seed, select the corresponding letter or number punch and line it up to the first position on the ColdTi plate. Using a heavy mallet or hammer, strike the metal punch with a single hit and ensure that a deep indentation is left on the plate.

Repeat the process for each number / letter of your seed words before fastening the plates together and sealing with the included holographic stickers.
