Trezor will end some reseller authorizations on January 1, 2027 to focus on partners it can vet closely
Trezor will end its resellers' authorization on January 1, 2027, days after Ledger found an LTE spy implant in wallets sold by CryptoBilis. Trezor says there is no evidence its own devices were compromised.
The Investor · Invest desk
Three separate figures. 80,689 Trezor customers whose data ShipMonk exposed, per Trezor's September update. 90 days: Ledger told CryptoBilis buyers from that window not to set up. More than $86 million in suspected thefts traced by Specter, not verified by Ledger.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Trezor customers whose data ShipMonk exposed | 80,689 customers | Per Trezor's September update | 10 |
| Ledger: CryptoBilis buys in the past | 90 days | Told not to set up their device | 11 |
| Suspected thefts traced by Specter, more than | $86,000,000 | Ledger says it has not verified it | 20 |
What happened
- Ledger's Donjon team says the unauthorized component reads the screen, decodes the recovery phrase when it appears, and sends the words out over LTE through an eSIM.
- Specter, an onchain investigator, put suspected thefts at more than $86 million. Ledger says it has not checked that number.
- Affected resellers get no new stock but can keep selling what they hold through Black Friday and the holiday season.
- In August, shipping partner ShipMonk exposed Trezor customer data, and Trezor's September update put the total at 80,689 customers.
Why it matters
- constraint Ledger says the implant leaves the key chip and the operating system unaltered [c3], so a tampered wallet looks and works normally and a buyer's only control is where the unit came from.
- cost The cost falls first on resellers, who lose supply after the holidays, and then on Trezor, which weighed revenue and distribution against its own presence country by country [c9] and chose to give up some of that revenue.
- contradiction Trezor's 2022 advice named authorized resellers as one of two places to buy [c12]. Sanders now says the cut reflects how many partners Trezor can vet closely [c16]. The safety of that channel now depends on the length of the list.
- exposure A buyer who finishes set-up on a tampered unit hands over the whole balance, because whoever holds the 24-word phrase can empty the wallet from anywhere [c15].
Trezor frames the cut as a preventive step taken out of caution [16]. Its post gave the reason in one sentence: "Following recent supply-chain incidents, we decided to reduce the number of resellers so we can more effectively check those we work with," Trezor wrote [4].
The letter to the affected resellers is gentler. Trezor CCO Danny Sanders shared it, and it reads: "I am sorry. This decision says nothing about your effort or the way you represented us." [5] The resellers that remain will work under a revised legal framework, with stricter requirements for sourcing, storing and handling devices [15]. Neither the post nor the letter says how many resellers are affected [14].
Count the incidents in the account and they do not show that supply chain is now the main self-custody risk. Of the three (the 2022 counterfeits, the ShipMonk exposure, the CryptoBilis implant), two involved altered hardware [17]. In both hardware cases Trezor places the seller outside its authorized list: the counterfeit Model T wallets of May 2022 were sold on a Russian marketplace by a seller that was not an authorized reseller [8], and Trezor said CryptoBilis had already dropped off its list of sellers and that it had not received a single report of a tampered Trezor sold by that retailer [19].
We think buying from the maker is sound procedure, and Ledger's own instructions show why. Ledger advised anyone who had bought from CryptoBilis within the last 90 days to leave the device unset, and anyone who had already set one up to move funds to a new seed phrase on a device bought from Ledger [11]. We do not think three incidents support the larger claim. They show where tampering got in, and ranking supply chain against other ways to lose a wallet would take loss counts by cause. The counter-thesis has some force. Trezor is giving up reseller sales on a precaution, and a vendor that does that has judged the risk of tampering to cost more than the sales it loses.
If nothing further surfaces before January 1, the cut stays a precaution with no demonstrated failure behind it. If a tampered unit is traced to a surviving authorized reseller or to Trezor's own store, the shrunken list was not enough and the buy-direct advice fails with it.
What to watch
- Whether Trezor names the number of resellers and the countries affected before the January 1, 2027 cutoff.
- Whether Ledger verifies Specter's loss tracing or publishes its own count of victims.
- Whether Trezor publishes the updated legal framework and sourcing, storage and handling rules for the resellers that stay.
