Krux has undergone such huge improvements over the past year that maybe it's good to have a new thread for it?  Maybe not.  I don't know.

I'm a huge fan of Krux.  I mean, come on now...  look at this thing:



That UI is dead simple, which means it's easy to use.  It runs on Maix Amigo hardware, which has a large touchscreen and can be found for as little as $50.

Air gapped.
Stateless.
Seed QR - with encryption!
Passphrase QR - no more typing!

It's easier to load a seed and passphrase on Krux than it is to enter the PIN to unlock a Trezor/Ledger/ColdCard.

Let's load a seed:



Note that where it says "From Storage," they mean from a micro SD card.  Not only can you save seeds to micro SD...  you can save encrypted seeds.  And you can scan a QR of the encryption key.  Don't have a QR for your decryption passphrase?  In the Tools menu, there's an option to make one.

Here's an encrypted Seed QR I made as as an example.  And here's the key to decrypt it:


Krux can make and scan passphrase QRs too.



The Maix Amigo's large touchscreen makes everything you'd do with a hardware wallet so much easier.







Want to make a SeedQR?  It's easy, especially thanks to the large screen.







Does Krux do Testnet?  You bet.  "Network" means Bitcoin Mainnet or Testnet.



I especially appreciate that the word "test" stays on the screen when you're using Testnet, to help avoid making any mistakes.  Well done!



If somebody made high end hardware for this and released it for $200, the hype would be insane.

Krux is a fantastic project.  Pair it up with BlueWallet or Sparrow as a companion app, and you've got a killer combo.
