A third-party proposal in Sparrow Wallet to show an advisory warning when a user selects a COLDCARD in the device flow, opened 6 Aug 2026 by nrobi144 and approved by skwp the same day. Held because wallet software warning its own users is a distinct strand of the response from vendor advisories and upstream library fixes: it puts the notice where a person is about to use the device. Detection keys on the exact COLDCARD wallet model, so subclassing importers do not trigger it. The author states the change was drafted with LLM assistance and that he could not run a full local build.

Every check is recorded, including checks that found no text change. A detected edit is therefore bounded between two checks. The publisher's exact save time is not observable from this record. Last checked .

    +Good question @PrinceOfEgypt. This PR hooks TitledDescriptionPane, so the warning shows across every Coldcard selection/import surface (file/QR import, airgapped keystore, USB, export) — but you're right that it does not fire when an already-created Coldcard wallet is simply opened/loaded.
    +A load-time acknowledgment (e.g. "I confirm I regenerated a secure seed on fixed firmware or with ≥50 verified dice rolls") is a good idea, but it's a meaningfully larger change — persisted per-wallet acknowledgment state + a dialog/banner in the wallet-open path — and I'd want it built and tested locally before proposing it (I flagged in the PR that I couldn't run a full Gradle build here). Happy to open it as a separate follow-up if @craigraw thinks the load-time prompt is worth adding; this PR keeps the scope to the additive, low-risk selection-time warning.

    +I agree, it's a larger change, but given the real risk of fund loss I think it's valuable (and probably the "right thing" to do). I unfortunately can't work on a PR myself at the moment because of some work deadlines.. we'll see what @craigraw thinks. Another idea I had was something like a "MOTD" type feature where urgent messages could be shown to users when they launch sparrow.. but that would require backend infrastructure and other changes

1 presentation-noise difference. Sidebar, ticker and other page chrome churn that our review classified as not being a change to what the source says.
  • +5 -3 Only GitHub header chrome changed. The 'Sign in' and 'Appearance settings' labels split onto separate lines, and the search prompt changed from 'Type / to search' to 'Search/'. The pull request content was unchanged.
