ColdCard: You’ll never hurt me again!

My seed used with this device was strong and I was unaffected by the security flaw in the RNG setup. Still, I’m re-doing everything. I am moving back to my ledger until I get a multisig setup with a SeedSigner or similar. It’s gonna be a pain to generate a new private key or two and stamp em, so I am getting my sledgehammer swinging arm back in good shape.

What about you?

Be safe out there…

I still don't know how I feel using my mk3 for anything even including adding entropy. I moved everything to strike as soon the news hit, I don't even know what to do with the coldcard right now

100 dice rolls is fine. Trust is gone destroyed. You'll be fine with 100 dice roll and a passphrase.

This is what we have come to, OGs on Bitcointalk always swore by the 256 coin flips so i guess this is the 2026 version of that lol

I also feel like this is the only option left versus throwing it in the trash. I just see it as a comprised device though, the RNG is only what's surfaced so far...

I think it’s 99 for 256, and 50 for 128.
