Bitcoin Developer Warns Against Singlesig After Major Coldcard Hack

Bitcoin developer Peter Todd is raising alarms after a critical security flaw allowed hackers to drain 594 Bitcoin from Coldcard wallets. The incident involved an entropy bug that made the devices vulnerable to brute force attacks. Attackers successfully targeted these wallets to steal funds worth roughly 38 million dollars.

Todd argues that the breach highlights the inherent risks of relying on single signature wallets. He suggests that using one device as a single point of failure creates a dangerous window for attackers. This event serves as a sharp reminder that even popular hardware tools can face technical issues that put user funds at risk.

Market participants are now reconsidering their storage strategies. Many experts are recommending multi signature setups to add extra layers of security. Traders should watch for official security patches from hardware manufacturers and consider if their current storage methods provide enough protection against these types of technical bugs.
