Coldcard Was Just the Beginning
August 5, 2026
Signal vs. Noise, a show from Onramp Media, examines the Coldcard hardware wallet's reported $130 million security incident and argues that AI-assisted vulnerability discovery is reshaping software security risk broadly, including for bitcoin custody tools.
Signal vs Noise: Jackson Mikalic, Brian Cubellis, and Liam Nelson - joined by guest co-host Cam Stromme, filling in for Michael Tanguma - put four stories on the shot clock. Coldcard's $130 million disaster was supposed to be a one-off. The panel makes the case it's the opening move in a much bigger reckoning: AI models are now finding vulnerabilities across software faster than humans ever did, and nobody knows yet what else gets found. They also break down OpenAI's Astra solving 10 decade-old math problems, the US and Japan's yen intervention, and Iran's on-again Strait of Hormuz deal. Where's the signal, and where's the noise?
