    I had a mk3. Got an email notifying my of a security flaw from coldcard wallets. I made a test transaction (5% or my stack). When I went to make another one, I get an error "not enough funds"...
    
    Wallet drained. I'm feeling shattered right now. I don't even know what to do.

    The email was from a crypto news source, not coinkite. That was how I found out about the vulnerability. I searched online to confirm it.

How to check this yourself

The excerpts and plain unified diffs above show the text this project held and how it changed. To verify a quotation, compare it against the page itself or against the Internet Archive's copies, which are independent of this project.

Complete captures are held offline rather than mirrored here, so this page shows diffs and excerpts. If a quotation is ever disputed, the full copy can be produced. Ask.
