Broadcasting a normal Bitcoin tx is announcing your move before you make it. It sits in the public mempool where everyone can see it before it confirms.

Normally that's harmless, but right now it isn't. If your keys are in the weak-Coldcard set, that announcement…

Have to give Saif a ton of credit as someone who previously advertised for ColdCard -- he reached out to me over the weekend to fast track an episode about our project. If you haven't leaned into SeedSinger, this may be a good primer in light of the recent…
