    title: MK4 TRNG + added dice rolls + passphrase
    body:
    Wondering how vulnerable this 24 word setup is. I see you recommended all mk3 users switch to wallets with seeds generated by dice rolls. Should I set up a new wallet with only dice or is RNG with around 100 dice rolls okay?

    Only you can decide that. 
    
    Personally this would be enough reason for me to switch to another wallet.

    Pretty much any method other than the one following the exploited method will not lead to a deterministic reconstruction of your seed.

    Dice roll method is unaffected, because it bypasses flawed RNG in Coldcard. Use real dices to roll and record the outcomes on a paper, then use that entropy to generate seed, using popular offline script from Ian Coleman, then use that seed for any hardware wallet of your choice.
    
    Do not use Coldcard's dice roll function.

    Excerpt only. The complete copy is held offline and backs quotations on this site. The original publication remains the canonical public source.

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.
