A friend of mine was an early Bitcoin adopter with a hold strategy using paper wallets. He stored his paper wallets inside an Altoids Tin, and the Altoids tin inside a safe. After several years, the ink started to fade. My friend doesn’t trust commercial hardware wallets (“Black boxes, you know…”) and online platforms (“Didn’t we learn something after MtGox?”).

So I’ve decided to give it a try and develop a basic experimental cold hardware wallet with the following requirements:

#1 Little enhancement over paper wallets
#2 Should fit the same Altoids tin

After a few days… I’ve came out with the Alt Wallet.”
