Question about Coldcard. Is there a "check" that i can do periodically on the coldcard, just to make sure it functions properly. I only turn it on occasionaly to see that the "ready to sign" comes on. Otherwise i only send btc to it with Sparrow wallet. Asking because i'll be helping a friend set up, and i want to give her good best practices advice.
I do transactions once in a while just to make sure it works😂😂😂
I have the same flow as you. Only I never even take out my coldcard at all. One way in through Sparrow.
What is your plan if the cold card does not say "ready"?
I use my coldcard with the Nunchuk wallet on Android, and it has a feature where you can do a health check on the CC to make sure it works. Casa has a similar functionality, but you have to have an account with them.
Here is the screen in Nunchuk. I think you may not even need to import the wallet itself, but just add the coldcard as a signing device and you can still run the health checks. I'm going to test this using the Guest mode in Nunchuk and get back to you.
Ah, good to know.
Best practice would be to leave the device alone and focus on securing your backup. That is where all of your attention should be.
I know you paid good dollar for the coldcard, but that device IS the expendable part of your setup.
Set it to kill itself after a few pin fails, set up a brickme pin in case someone tries to coerce you into unlocking it for them. Then leave it alone.
If it breaks, you lost your ability to sign a transaction immediately, you'll have to buy a new one and wait for delivery etc. But that is okay.
Focus on the backup(s). Too many copies = easy to steal, too little copies = easy to lose, seedxor = can help find a compromise between the two.
The best security is always unique to you and your circumstances. Focus on the backups.
That makes sense, my mind has been spinning over this for a while.
Keep up the good work asking the right questions.
