“There’s a lot of chaos right now in the ecosystem. We absolutely understand that many people are being bombarded with security issues right now,” said Bitcoin developer Calle.

A Bitcoin security group made up of just 16 volunteers said they have found nearly 5,000 potential issues during a rapid AI-assisted review of projects in the Bitcoin ecosystem.

Bitcoin Red Team is a volunteer security effort that includes Rob Hamilton, CEO of AnchorWatch and Bitcoin developer Calle, among others, which has been using AI tools and human review to scan open-source Bitcoin-related repositories for vulnerabilities.

“We’re averaging on the order of 1 critical exploit per hour per person,” said Calle in a

post

to X on Wednesday.

The launch of the Bitcoin security review campaign comes just days after the

Coldcard hardware wallet hack

, which has seen over $100 million in Bitcoin stolen.

According to Calle, in the first 29.8 hours of its operation, its team has found 4,962 potential issues across 390 projects. As many as 720 of them are considered high- or critical-level issues. So far, 21.4% of findings have been able to be reproduced.
