Official Trezor warning that a seed generated on an affected Coldcard and later moved to a Trezor remains affected, because the weak randomness was introduced at seed creation. Trezor advises generating a fresh seed on the Trezor and carefully moving funds. Held as dated vendor guidance from a hardware-wallet maker during the incident response. The advice is Trezor's own and is not independently verified here.

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