I imagine many people here, on the advice of @ODELL and @MartyBent have also been using the (fantastic) Sparrow Wallet from @craigraw In light of recent events with coldcard, it would be great if Odell and Marty (maybe via @OpenSats ?) paid for a proper/formal code review of Sparrow. I know those are expensive and probably out of scope for Craig to do. And while Sparrow is "battle tested", we all thought the same thing about Coldcard. I believe a formal security team led audit of Coldcard would have had a good shot of finding the RNG bug. Just an idea, especially as a lot of people are in the 'repenting' mode right now, there may be some ways to turn that into action.
