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!
I did, and I think about the number all the time because I don't recall what the number is. I bet I find out someday.

It's 256. But I don't know if all actions consume one slot or if some actions are chunkier than others.
Good to know. Do you know if there is a way to check the supply?

You can check in the Danger Zone menu
Cool thanks
