Hey Product Hunt! 👋
I'm Maxence, the solo developer behind SeedCrypt.
The idea came after I nearly lost access to a wallet because of a damaged paper backup. Just water — nothing dramatic. But it was enough to make me realize that the standard advice of "write it on paper and hide it" is genuinely fragile.
I spent weeks looking for a proper solution. Everything I found either required cloud sync, an account, or just didn't feel trustworthy enough for something this critical. So I spent six months building my own.
SeedCrypt encrypts your seed phrases locally with AES-256-GCM, stores the encrypted file wherever you want — USB, external disk, multiple locations — and never makes a single network request. If someone finds your backup, it's completely useless without your password.
A few things I'd love feedback on:
Is the pricing fair for a one-time license?
What features would make this more useful for your setup?
Would you feel comfortable using this for your most critical wallets?
Free tier lets you try it with 1 seed — no email required.
Happy to answer any questions about the technical implementation, the crypto stack, or anything else 🙏
