Nearly 120,000 Crypto Hardware Wallet Buyers Affected by Data Exposures in 2026
Nearly 120,000 cryptocurrency hardware wallet buyers have had their shipping addresses exposed in 2026, with Keystone becoming the fourth wallet maker linked to a customer data breach this year, according to information shared by Coin Bureau. The incidents highlight a potential privacy risk for crypto users: hardware wallets can keep private keys offline, but personal information collected during purchases may remain accessible through retailers, shipping partners and third-party services.
The reported incidents involve Ledger, Trezor, SafePal and Keystone. They illustrate how customer information can be exposed outside the wallet device itself, including through e-commerce systems, shipping services and order-tracking tools.
Four Hardware Wallet Brands Linked to Incidents
Ledger was affected in January, when customer names, addresses and order information were exposed through its e-commerce partner, Global-e. The incident involved information associated with purchases rather than a reported compromise of the hardware wallet's offline key storage.
In August, Trezor customers were affected by an exposure involving nearly 80,000 addresses through the company's shipping partner. The incident placed customer delivery information at the center of the security concern, illustrating that purchasing a device designed to protect cryptocurrency keys does not eliminate every risk associated with handling personal data.
SafePal was also affected in August. According to Coin Bureau, the incident exposed the addresses of 39,798 customers through an order-tracking plug-in. The reported figure identifies the number of customers whose addresses were exposed in that incident.
Trezor appeared in the reports again in September, when fake security alerts were sent to approximately 347,000 newsletter subscribers. This incident involved fraudulent messages distributed to a large audience, rather than a stated figure for exposed shipping addresses. It nevertheless underscores the importance of distinguishing legitimate security communications from deceptive messages that could target cryptocurrency users.
Offline Keys Do Not Protect Every Piece of Customer Data
Hardware wallets are designed to keep cryptocurrency private keys offline, helping users protect the credentials needed to authorize transactions. However, the purchase and delivery process involves separate systems that may collect names, shipping addresses and order details.
Those records can be held by a wallet manufacturer, an e-commerce provider, a shipping partner or an external plug-in. If one of those systems exposes customer information, the resulting privacy risk exists even if the hardware wallet itself continues to store keys offline.
Shipping addresses are particularly relevant markets because they connect a person or household to a cryptocurrency product. The reported incidents do not, by themselves, establish that private keys were stolen or that customer wallets were compromised. Personal-data exposure and cryptocurrency theft are different types of security incidents, and the available information should not be treated as evidence that funds were lost.
Coin Bureau's account places the Keystone incident alongside the reported cases involving Ledger, Trezor and SafePal. Across the incidents described, the central concern is the handling of customer information by the broader purchase and communication systems surrounding hardware wallets.
With nearly 120,000 buyers' shipping addresses reportedly exposed in 2026, the cases show why protecting cryptocurrency assets and protecting the personal information of their owners are separate security challenges.
