Watch the Video

This podcast is an edited version of the video, where I have removed the unboxing section, as it's challenging to follow in an audio-only format.

After reviewing the Keystone 3 Pro, I wanted to inspect the Keystone Tablet Plus, a steel slab similar to the Coinkite Seed Plate and the Scaletron Crypto Seed Capsule, both of which I've reviewed.

Watch the video below for my review, but also read the text below, as it includes one additional PRO and one additional CON that I did not mention in the video.

3 Pros of the Keystone Tablet Plus

1. Reusability! Unlike the Coinkite Seed Plate or the Scaletron Crypto Seed Capsule, the Keystone Tablet Plus is reusable. If you change seed phrases, you rearrange the letters accordingly. 

2. Extra security! Two security features make the Keystone Tablet Plus stand out. First, the package includes tamper-evident tape. Second, it has a hole that allows you to put a padlock. Admittedly, neither of these features prevents a thief from outright stealing the metal plate and cutting the lock off. However, they can alert you if someone is trying to snoop on your seed phrase slyly and quietly drain your wallet.

3. Ease of use. I forgot to mention this in the video. Unlike the Coinkite Seed Plate or the Scaletron Crypto Seed Capsule, the Keystone Tablet Plus doesn't require you to awkwardly and permanently bang out your seed phrase. It

3 Cons of the Keystone Tablet Plus

1. No passphrase option. I forgot to mention this in the video review, but I thought about it after reviewing the Scaletron Crypto Seed Capsule.

2. 304 stainless steel might not survive a super-hot fire. It should survive a standard house fire, but if it's unlucky enough to go through hell, it may not make it. An affordable solution to this is to place it in a fireproof envelope to double your protection.

3. Won't survive a crushing. True, but this is highly unlikely.

🌱 What Is BIP39?

Seed phrases usually use the BIP39 word list. 

BIP39 seed phrases are a cornerstone of modern cryptocurrency wallets, and understanding why they exist—and how they function—reveals a great deal about the balance between security and usability in cryptographic systems.

BIP39 stands for Bitcoin Improvement Proposal 39, which defines a method for generating and using mnemonic phrases (typically 12–24 words) to back up and restore wallets. These phrases are derived from a specific list of 2048 words.

✅ Human Usability

• Random strings such as x8F$3kL@9z! are hard to remember, write down, or type correctly.


• BIP39 uses real words that are easier to recognize, pronounce, and transcribe.
