Ledger unveils Atom, an $899 Android signer with Solana Mobile integration

Ledger announced Atom on October 15, a touchscreen Android device the company bills as a signer rather than a hardware wallet, with Solana Mobile integration and controls for AI agents, at its Op3n event in Paris. The company said in a post on X that Atom combines hardware security, everyday apps and control over AI tools in one device.

One device, two operating systems

Atom runs Android Open Source Project software alongside Ledger OS on a secure element rated EAL6+. An FPGA chip separates the Android environment from Secure Mode, the isolated space where transactions are signed. A physical switch cuts power to the camera and microphone, and both shut off automatically whenever the device enters Secure Mode. The hardware carries a 6.77-inch OLED display, a rear camera, a 4,000mAh battery and a Qualcomm Dragonwing chip with a data-only eSIM.

Solana Mobile named Ledger its first hardware expansion partner, and the Seeker app plus the Solana dApp Store, which lists more than 1,500 dApps, will ship preinstalled on Atom, with signing handled by Secure Mode. Solana Mobile said it has sold over 200,000 devices and processed more than $13 billion in transaction volume across 154 million transactions.

Pricing and delivery

The limited Founder's Edition costs $849 with a $100 fully refundable deposit to reserve one. Regular orders will cost $899 after launch, Ledger said, and the device will be sold only through Ledger's website. Deliveries are expected to begin in summer 2027, pending certification. That sits far above the company's current wallet lineup, which spans $69 to $399.

Atom's encryption will incorporate post-quantum cryptography compatible with standards from the U.S. National Institute of Standards and Technology, the company says on its announcement page. Kraken is exploring support for Atom and whether customers could use Secure Mode to approve actions on the exchange, building on a September collaboration between Payward, Kraken's parent, and Ledger.

Launched mid-investigation

The announcement lands days into Ledger's probe of unauthorized implants in wallets sold through the Southeast Asian reseller CryptoBilis. Ledger's security team said the implant can capture recovery phrases shown on screen during setup and transmit them over a mobile network. Onchain researchers have tied the incident to suspected losses of more than $86 million, a figure Ledger has not confirmed and which varies between estimates. Ledger asked resellers in six Southeast Asian countries and Hong Kong to pull devices from shelves on October 13, and said on October 14 that inspections across Germany found no tampering, with no implant-related losses reported in Europe.

Ledger says Atom's tamper sensors sit on a separate battery and work while the device is off, and that the Core Protection feature will block the screen-reader implants from the recent incident. The Core Protection feature will explicitly block the screen reader implants from this weekend's incident," a Ledger spokesperson said. The claim has not been independently tested. Ledger declined to disclose sales targets.
