Bloomberg's @EricBalchunas argues the ColdCard vulnerability could push more bitcoiners toward ETFs. What many in the bitcoin community saw as a bug, trusting "dorky boomer TradFi" with custody, might now look like a feature. These are "large, established financial institutions with decades of experience safeguarding client assets" compared to "a Canadian co with 5 employees."

Sen. Jon Husted urges Senate to pass the bipartisan Clarity Act before August recess: “We have a bi-partisan bill, we are ready to go.” “It’s time for America to lead.”

American HODL received a phishing email urging him to download a fake "ColdCard Desktop" app. Scammers are exploiting the panic around the ColdCard vulnerability to trick people into downloading malware. As he points out, there is no ColdCard desktop app and there never has been. Stay vigilant.

ColdCard is pushing back on claims that the latest firmware patch permanently bricks devices. They say the TRNG fault is volatile, nothing gets written to flash, so a full power cycle should recover the device. A new proposed patch further hardens RNG recovery with bounded retries, seed-error detection, and discarding stale output.

James O'Beirne reveals he came to the same conclusion about ColdCard's firmware back in May 2025. While auditing the code, he flagged concerns about a suspicious library called libngu that was handling random number generation and advised the ColdCard team to rip it out. He was told, "if something was wrong, we'd already know about it by now."

Rob Hamilton posted an update on what Bitcoin Red Team has been up to. They've spent around $20K scanning 150+ repos across the bitcoin ecosystem and made over a dozen responsible disclosures. He built an AI agent harness that's already finding critical issues, and they're also working with OpenAI's Cyber Harness for the most load-bearing infrastructure. Plan is to open source the tooling so any project can point it at their own repos.
