Today I learned about unrecoverable MCU key slots on the ColdCard.

Apparently you have a limited number of destructive actions (such as clearing the seed words or messing around with trick PINs) and after that, it's BRICKED (I guess?)

So, if you use the ColdCard as an ephemeral signing device (like a SeedSigner or a Jade in Stateless Mode, except you manually wipe the device), you are limited to the number of times you can enter a new seed before you turn the device into a potato.

Don't tell me you knew about this! You didn't!

Since we’re on the coldcard topic. If you use the coldcard as hardware wallet and your hardware suddenly stops working, is there a way to back up the information on the coldcard so you van back it up on another coldcard? Or what do you do to have a backup in case of hardware failure?

You can do a full backup of the seeds, secure notes and setting with a (functioning ColdCard using the Advanced/Tools -> Backup function
