The Cobo Tablet comes with a set of 252 letters. The recovery seed is assembled manually and it is extremely easy to do so. You can use both sides of the Cobo Tablet, and store 12, 18, or 24 words.
That is up to 96 letters of sensitive information in a couple of minutes, ensuring the privacy and security of your data.
Why does it have only 4 slots for a word??
The Cobo Tablet is based on the BIP39 Code that is used to generate the mnemonic keys. It is a specific list of 2048 English words that has been carefully curated so that the entire word can be identified with just the first four letters. That’s why the Cobo Tablet has only four-letter slots.
If a word has just three characters, use a letter tile in reverse to fill in the space.
