The goal was to test my tool Alek Of Clubs; a simple algorithm that given a standard deck of 52 cards (only 35 are used), takes a permutation, and translates it into a 12-word mnemonic seed. The keys of the mint address for Sesostris are stored using this method, just a deck of cards sitting on my desk.

About The Algorithm:
It is bijective, but of course it's not advised to shuffle the cards yourself; The checksum will most likely fail, and it's unsafe. The typical pipeline is:

1. You generate your keys along with the mnemonic phrase using cake, phantom, electrum, etc. Pick your poison.

2. You take the mnemonic phrase, and use the GUI or CLI from Alek Of Clubs; to translate it into a permutation.

3. For this step you need to buy (or steal (don't steal)) a deck of cards; You'll build the permutation in the exact order that the program gave you, using your physical cards. Then you can store them wherever you want indefinitely.

4. Once you want to recover the mnemonic phrase, you have to input the cards onto the program using the GUI or CLI from Alek Of Clubs;, in the exact order you stored them.

5. Only the first 35 cards are important (35 cards ≈ 133 bits of entropy), the other 17 aren't even a checksum so you can ignore 'em.

Tip: create an account and post some poetry along with your SOL address and i'll mint some tokens for you.
