Ledger Nano X

Ledger Nano X offers Bluetooth signing from compatible iOS and Android phones and USB-C access from a desktop computer. Users review transactions on its monochrome OLED screen and confirm them with physical buttons. The self-custody wallet keeps signing keys on the hardware while Ledger Wallet (formerly Ledger Live) manages accounts for assets such as Bitcoin, Ethereum, and Solana on the connected phone or computer.

Overview

Ledger Nano X combines a compact form factor with a certified secure element and Ledger OS. Transactions are prepared in Ledger Wallet or compatible third-party applications and must be confirmed directly on the device. This separation between transaction creation on a connected device and transaction approval on the hardware wallet is intended to provide key isolation from the connected phone or computer.

History and Background

Nano X is part of Ledger’s Nano series and was introduced to support a more mobile-first workflow than USB-only devices. Its Bluetooth capability is designed for users who prefer managing accounts from a smartphone while retaining hardware-based signing. Over time, Ledger has continued updating its software and firmware environment, including renaming its companion app to Ledger Wallet.

Core Products and Services

• Private keys are generated and stored on the device and used to sign transactions locally.
• Ledger Wallet provides portfolio visibility and account management. It also handles firmware updates and supported services.
• Nano X supports cryptocurrencies and tokens, with NFT access through compatible apps. Third-party wallet integrations expand asset coverage.
• Bluetooth connects the Nano X to iOS and Android devices. USB-C supports desktop use.

Technology and Features

Ledger Nano X is built around a secure element chip and Ledger OS. The device uses a monochrome OLED display and physical buttons for navigation and approvals, which helps ensure transaction confirmations happen on the trusted hardware interface rather than solely on the host device.

• The Nano X uses Ledger OS and an ST33J2M0 Secure Element with CC EAL5+ certification.
• The display is monochrome OLED, 128 × 64 px.
• Nano X connects to smartphones through Bluetooth (BLE 5.2). USB-C supports desktop and Android use.
• The Nano X measures 72 mm × 18.6 mm × 11.7 mm and weighs 34 g.
• The wallet is designed for use with Ledger Wallet on desktop and mobile, and with third-party wallets for broader asset and dApp coverage.

In practice, functionality can vary depending on whether an asset is handled directly in Ledger Wallet or through a supported third-party application, particularly for advanced token and NFT workflows.

Use Cases and Market Position

Ledger Nano X supports long-term self-custody and regular signing with hardware approvals. Typical use cases include storing a diversified portfolio, using the device as a signer for on-chain activity, and pairing it with third-party wallets for specialized ecosystems. The combination of Bluetooth and USB-C makes it relevant to users who want flexibility between mobile and desktop environments.

Risks and Considerations

• Hardware wallets do not eliminate self-custody risk. Users must securely store recovery materials. Loss can make funds unrecoverable, and exposure can enable theft.
• A hardware wallet protects keys, but users can still approve harmful transactions if they interact with phishing sites or malicious dApps. On-device review remains critical.
• Some assets and advanced features may require third-party wallets. Users should confirm compatibility for specific chains, tokens, and NFT standards.
• Firmware updates and companion app integrity matter. Users should follow official setup guidance and verify they are using legitimate software sources.
