Trezor is reducing its authorized reseller network after a series of hardware-wallet supply-chain incidents raised new questions about how signing devices reach customers.

In an October 13 post, Trezor said it decided to cut the number of resellers so it can more effectively check the companies it works with. The hardware-wallet maker stressed that it has found no evidence that Trezor devices have been compromised and described the change as preventive.

Following recent supply-chain incidents, we decided to reduce the number of resellers so we can more effectively check those we work with.

Let us be very clear: there is not a single piece of evidence that Trezor devices have been compromised.

This is a preventive step, taken… https://t.co/pKF4tCHo5c

Trezor says the reseller reduction is a precautionary supply-chain measure, not a response to a confirmed compromise of its own devices.

The move follows reports involving tampered hardware wallets sold through third parties. BitcoinVersus.Tech recently covered Ledger confirming an unauthorized hardware implant in a wallet sold by reseller CryptoBilis. Trezor’s response shows how quickly that incident is spreading beyond one manufacturer and turning reseller oversight into an industry-wide security issue.

Bitcoin Magazine reports that affected Trezor partners were told their authorization will end January 1, 2027. Trezor has not publicly disclosed how many resellers are being removed. Its official purchasing guidance continues to recommend buying through the Trezor Store or an authorized reseller.

Trezor’s official supply-chain security walkthrough explains its tamper-evident packaging, firmware checks, device authentication and other defenses against counterfeit or modified wallets.

The broader lesson is that self-custody security does not begin only after a wallet is powered on. It includes manufacturing, packaging, shipping, reseller custody and device initialization. That concern has become more visible after the Coldcard wallet attack and BitcoinVersus.Tech’s coverage of a Trezor phishing email sent from a legitimate domain.

For Trezor users, the confirmed development is the reseller-network change itself. There is currently no evidence in the company’s announcement that Trezor hardware has been compromised through the incidents that triggered the review.
