Getting Started: Blockplate

How It Works

Blockplate is the original and inventor of "center punch style" seed storage. It was the first of its kind to utilize an automatic center punch to store bitcoin seeds on metal. It has been described as "the fastest and simplest" and "the most robust".

Applicability: Blockplate 12 | Blockplate 24


Grab your letter locator template guide and on the lines at the bottom, write the first 4 letters of each word in your seed phrase.

Why only the first 4 letters?

Circle the numbers at the top corresponding to the numerical order of your words.

Step 1

Peel your letter locator template guide from it's backing and stick it on your Blockplate.

Position the template as so the letters fall inside each box.

Step 2

With a marker, mark the grid with the first 4 letters of each word in your seed phrase. Why only the first 4 letters?

Place a small dot ( • ) in each box corresponding with the letters in each box (also on the left-most edge). 

Note: For 3 letter seed words, leave the last space blank/empty.

The numerical order of your words are indicated by the numbers at the top edge.

Step 3

Double check each letter and word. 

Yes, this is so important that it is its own step.

Using an Automatic Center Punch

In the next step, you will be using an automatic center punch to make a physical, permanent holes on your Blockplate.

To use, place the tip at the first marking where you want to make a hole. Press and hold the handle down firmly with increasing pressure until you hear an audible "click" (unmute video audio for sound). It should feel like you're compressing a spring until you feel a "pop".

We recommend picking up a center punch from your local hardware store or an online marketplace (paid link).

Step 4

Using an automatic center punch, punch down at each marking.

This will make a physical and permanent indentation in at each marking that will show up within each box.

Step 5

Peel the template off to reveal your seed physically and permanently marked on steel.

Securely discard your used template.

Repeat on the backside with your remaining words.
