Was Trezor okay? Grok 📕 Yes, Trezor was unaffected. This issue was specific to Coldcard (Coinkite) and did not impact Trezor. Trezor’s official account (@Trezor) clearly stated on July 31, 2026: “Trezor users’ funds are safe.” The Coldcard issue was limited to their proprietary firmware and a flawed random number generation method on certain devices. Trezor does not share this code. Trezor has always combined multiple independent sources of randomness (device hardware + host + secure element on newer models). Note: If you generated a seed on a compromised Coldcard and later imported (restored) that seed into a Trezor, the seed itself may have been created using weak randomness and could still pose a risk. In this case, you should generate a new seed directly on your Trezor and carefully transfer your funds. @Trezor In summary: Trezor’s seed generation and devices themselves have no issues—users who only use seeds generated directly on Trezor are safe. Other major hardware wallets, such as Ledger, are also confirmed to be unaffected by this specific bug.
