Galaxy Research states that the vulnerable COLDCARD firmware shipped on 17 March 2021 around block 674,951, and that no coin identified in waves 1 to 3 was created before that block. This bears independently on the affected-range lower bound: 17 March 2021 is the v4.0.0 release date recorded here, not the 29 March 2021 v4.0.1 date that the vendor advisory uses as its stated boundary.
This post is registered as evidence and has a locally held capture. The original remains the canonical publication. Last checked .
This post is held twice: here, with this project's own note on why it matters, and again as part of the conversation captured at , which is polled for changes. Both copies are the same post; neither is a separate event.
Snapshot and diff bodies for this chain monitor are held in the local evidence archive but withheld from the public site because they can contain the addresses of people who published nothing themselves. Capture times and reviewed change summaries remain available below.
