After the Coldcard disaster, Trezor is upgrading its wallets.

Trezor is rolling out firmware updates for its hardware wallets following a summer incident in which a firmware flaw on competitor Coldcard cost users millions of dollars, with only those who had set a strong passphrase spared. The German-language report from BTC-ECHO frames Trezor's move as a direct consequence of the Coldcard disaster, which hit Coldcard users hard in the summer. The update underscores growing security scrutiny across the Bitcoin hardware wallet sector after the exploit. No specific firmware versions, affected Trezor models, or patch timelines were detailed in the source material. Investors and users should watch for further technical details from Trezor on which devices are affected and what the new protections entail.
