Alice has used her hardware wallet for years and wants to be sure her paper backup really restores it. She enters the seed phrase into EntropyLab on an offline computer and confirms that the receive addresses match the ones her wallet shows, without ever restoring it on a second device. github.com/OogaBoogaX/entrop…

Yes, that would be a good feature to add.

Bob owns a hardware wallet but doesn't feel comfortable trusting the seed phrase it gave him. He rolls dice, turns the rolls into a new seed phrase with EntropyLab on an offline computer, and loads it onto his hardware wallet. Now he only needs to trust the hardware wallet for signing transactions. entropylab.online

Try EntropyLab online with test data. See how entropy becomes a seed phrase, keys and addresses. 🎲 For real seeds, download the HTML and run it on a fully offline computer. Never enter a real seed in the online version. entropylab.online

We're aiming for a v1.0.0 release by next week. Then we'll spend the next couple of weeks doing more testing and audits before presenting it at Tabconf.

Who’d be interested in a limited-edition “Seed Round” of EntropyLab merch to help fund our clankers for the next few weeks/months? I’m thinking a small run of a few different items...just 21 of each, individually numbered and tastefully branded with the EntropyLab logo. Each piece would be marked: Seed Round · x/21
