Zach Herbert recommends that affected users buy one of the devices Coldcard did not officially endorse, naming Foundation and SeedSigner. Held as a dated primary statement from a competing hardware-wallet vendor CEO on migration options after the incident. The recommendation is the poster's own and inclusion is not endorsement.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
