Ledger has unveiled Atom, a premium Android-based hardware device that combines everyday crypto applications with an isolated transaction-signing environment, positioning the product as a response to the tougher physical-security questions raised by an investigation into modified Ledger wallets sold through a third-party reseller.
Presented at Ledger’s Op3n event in Paris on Thursday, Atom is scheduled for initial deliveries in summer 2027, subject to certification. The limited Founder’s Edition costs $849, with customers required to place a fully refundable $100 deposit. Ledger said the device will cost $899 through regular orders after launch, placing it well above its existing hardware wallet range of $69 to $399.
Atom will be sold directly through Ledger’s website, according to Solana Mobile. Ledger did not disclose sales targets.
A smartphone-style device with separate signing controls
Atom runs the Android Open Source Project for applications while using Ledger OS and an EAL6+ certified secure element for sensitive cryptographic functions. EAL6+ is a high assurance level under the Common Criteria security certification framework, commonly used to evaluate resistance to sophisticated attacks on secure hardware.
Ledger said the device automatically changes between Standard Mode, where users can run applications, and Secure Mode, where they review and approve transactions. An FPGA, or field-programmable gate array, separates Android from the secure signing environment. That design aims to prevent an app operating in the Android layer from directly reaching private keys or altering the transaction details shown for approval.
The company is extending the concept of a hardware wallet beyond a single-purpose signing device. Atom is intended to run apps while preserving a dedicated area for key storage and transaction confirmation, a model that could appeal to users who currently rely on a phone for wallets, decentralized applications and messaging but want a more isolated method of authorizing transfers.
Ledger said Atom includes a physical switch that disconnects power from its cameras and microphone. Both components are also disabled whenever Secure Mode is active. The device is planned to support encrypted communication through GPG/OpenPGP and to use post-quantum cryptography compatible with standards developed by the U.S. National Institute of Standards and Technology.
Post-quantum cryptography refers to cryptographic systems designed to resist potential attacks from future quantum computers. Its inclusion gives Atom a longer-term security feature, although the immediate value for users will depend on which applications and communications functions ultimately adopt it.
Solana Mobile app and AI agent features are planned
Solana Mobile’s Seeker application is expected to be available on Atom. The app combines a wallet and decentralized-app store, while transaction approvals would take place through Atom’s Secure Mode rather than within the general Android environment.
Solana Mobile said it has sold more than 200,000 devices and recorded over $13 billion in transaction volume across 154 million transactions. In March, the company began making its mobile software available to other Android manufacturers, opening a path for Atom to use software originally developed for Solana-focused smartphones.
Ledger also plans to bring its Agent Intent system to Atom. The feature is designed for transactions proposed by AI agents, allowing a user to inspect and approve an intended action without giving the agent control over private keys. Ledger said Agent Intent will integrate with OpenClaw, and that the OpenClaw application will come preloaded on Atom.
The approach addresses a practical problem emerging around autonomous software: an AI agent may be able to find an opportunity, prepare a trade or interact with an application, but a human can retain final signing authority. The safeguards will depend on how clearly Atom presents the proposed transaction and whether users can identify malicious or misleading instructions before approval.
Ledger said Kraken is exploring support for Atom before launch. The work follows a collaboration between Ledger and Payward, Kraken’s parent company, announced in September to expand Ledger device support on the exchange. According to Ledger, the current evaluation includes whether Secure Mode can be used to approve actions on Kraken.
Tamper detection follows reseller investigation
The timing of Atom’s launch places its physical defenses under particular scrutiny. Ledger is investigating unauthorized modifications found in some existing hardware wallets connected to CryptoBilis, a reseller in Southeast Asia.
Ledger’s security team said an unauthorized implant could capture recovery phrases displayed during a device’s setup process and transmit them through a mobile network. Recovery phrases are the backup words that can restore access to a wallet, making their exposure potentially more damaging than the compromise of a single device session.
Onchain researchers have linked the incident to more than $86 million in suspected cryptocurrency losses. Ledger has not confirmed a total loss figure or said how the modified hardware was introduced into devices associated with the reseller.
In a Wednesday update, Ledger said it had inspected devices obtained from retailers and distributors across Germany and found no signs of tampering. The company also said it had not identified losses related to hardware implants in Europe. It has not said whether other resellers beyond CryptoBilis could have been affected.
Atom includes several features aimed at detecting physical interference before a device reaches or remains with a customer. Ledger said its secure element, microcontroller unit and FPGA are housed in a protected area monitored for drilling and forced-access attempts. The back cover is paired to the device, while tamper sensors can continue operating from a separate battery even when Atom is powered off.
Those measures target an attack category that conventional software updates cannot solve: a device altered before its owner begins using it. The reported CryptoBilis case involved alleged hardware capable of observing recovery words on-screen, meaning security depends on the integrity of manufacturing, distribution and the physical device itself, not solely on the wallet’s software.
Ledger’s direct-sales plan for Atom would give the company more control over its distribution path than a broad reseller model. Yet the device will not arrive for more than a year, leaving current Ledger users reliant on the company’s existing devices, secure setup practices and trusted purchase channels while the reseller investigation continues.
