Abstract:
Ledger releases Atom, a device that looks similar to a smartphone but is positioned as an encrypted asset signer and data terminal. It runs an enhanced version of the Android open source system and the independent Ledger OS: daily applications are run by the Android environment, and when sensitive operations such as private keys and transaction signatures are involved, it switches to the safe mode of Ledger OS. The device can connect to Wi-Fi or use 4G or 5G networks through a data-only eSIM, but it does not support cellular voice calls, text messages or emergency calls, so it cannot replace an ordinary mobile phone; Internet calls depend on third-party applications and network connections.
The design specifications announced by Ledger include a 6.8-inch, 60Hz AMOLED screen, a 50MP camera, support for 4K 60-frame video, a 4000 mAh battery, a body size of 78×164×9 mm, a weight of about 250 grams, and support for Wi-Fi, Bluetooth, NFC and USB-C. The device uses Qualcomm Dragonwing chip and is equipped with a fingerprint reader; Ledger claims that the security chip reaches the CC EAL6+ level and is ready for post-quantum cryptography technology. The company said it will provide five years of Android system updates, as well as spare parts supply for at least seven years after the last device was sold, and the battery will be user-replaceable.
Security architecture is the core selling point of Atom. Ledger stated that the Android environment and the Ledger OS security stack that saves seed phrases, private keys and signature operations are run by different chips; when a transaction is signed, the FPGA will cut off the Android system's control of the screen and touch input at the hardware layer, and the Ledger OS will independently display the transaction information and receive user confirmation. The device also has a physical privacy switch that cuts off power to the camera and microphone at the circuit level. Ledger claims that the area where the Secure Element, microcontroller and FPGA are located has an active anti-tampering mechanism. Unsealing the fuselage and removing the screen or back cover will trigger detection. The packaging is also designed to show whether it has been opened. These are design and protection claims disclosed by the manufacturer, which have yet to be verified by mass production and independent testing.
Ledger said that the device is also geared towards AI agent usage scenarios: agents can monitor the market, propose transactions or set permissions, but the final transfer still requires physical confirmation by the user through the device. Ledger plans to work with OpenClaw and emphasized that agents cannot gain direct access to wallets. The device supports encrypted communications, but the official website lists private messaging as "coming soon."
Atom is currently open for pre-order for the Founder’s Edition. US users need to pay a refundable deposit of US$100 in advance. The price of the Founder Edition is US$849, and the price will rise to US$899 after the official launch. Ledger's official website states that the device is expected to be shipped in the summer of 2027, and explains that the booking amount and final payment may change due to regional exchange rates. The company also lists benefits such as protective accessories, privacy screen protectors, Ledger Recovery Key, and $50 Bitcoin coupon for the Founder Edition.
The new product launch comes as Ledger investigates a supply chain hardware implant incident. Ledger confirmed that an unauthorized implanted circuit was found in a Signature device sold by Southeast Asian distributor CryptoBilis, which can read the 24-word recovery phrase displayed during initial setup and transmit it through LTE and eSIM. Ledger stated that it has been confirmed that the financial losses related to the incident involve equipment sold by CryptoBilis, but the number of people affected and the total loss have not yet been verified; the figure of more than 86 million US dollars cited by the media comes from third-party estimates, which Ledger has not yet confirmed. German retailers MediaMarkt and Ledger have also suspended store and online sales during the investigation. Ledger said that no financial losses have been reported in the device implant incident reported by the German customer.
