What is the storage capacity of the Ledger Nano X?

The Ledger Nano X has 2 MB of internal storage, which is significantly more than its predecessor, the Ledger Nano S.

Device Specifications and Storage Overview

1. The Ledger Nano X features 2 MB of secure flash memory, allowing users to install up to 100 different cryptocurrency apps simultaneously.

2. This storage capacity supports a wide range of blockchain applications, including Bitcoin, Ethereum, Litecoin, and various ERC-20 tokens.
3. Unlike traditional storage devices, the memory is optimized for security rather than volume, prioritizing encrypted key management over data size.
4. Applications are stored in an isolated environment through Secure Element (SE) technology, ensuring private keys never leave the protected chip.
5. Firmware updates are designed to be lightweight, preserving available space while enhancing functionality and security protocols.

User Experience with Multi-Currency Management

1. Users can switch between installed apps directly on the device without needing to uninstall and reinstall others, thanks to efficient memory allocation.

2. The companion application, Ledger Live, allows seamless management of installed crypto apps and helps monitor storage usage in real time.
3. When the storage limit approaches, users receive notifications prompting them to remove less frequently used apps to make room for new ones.
4. Each app varies in size depending on complexity; for example, Bitcoin and Ethereum take up more space compared to smaller token integrations.
5. The Bluetooth connectivity enables mobile interaction without compromising the air-gapped security model during transaction signing.

Security Architecture and Memory Protection

1. The 2 MB storage is partitioned into secured zones managed by the STMicroelectronics ST33 secure element, resistant to physical and software attacks.

2. All sensitive data, including private keys and recovery phrases, are stored exclusively within the secure element and never exposed to external systems.
3. Memory access is tightly controlled by the BOLOS operating system, which enforces strict isolation between apps to prevent cross-contamination.
4. Even if malware infects a connected computer, the hardware firewall prevents unauthorized access to stored cryptographic assets.
5. Firmware integrity checks occur at every boot, ensuring no tampering has occurred with the stored code or memory layout.

Frequently Asked Questions

How many cryptocurrency apps can be installed on the Ledger Nano X?The Ledger Nano X supports installation of approximately 100 cryptocurrency apps at once, depending on the individual size of each app. Larger blockchains like Ethereum require more space than simpler token interfaces.

Can I expand the storage of the Ledger Nano X?No, the device does not support external storage expansion. Its 2 MB of internal memory is fixed and cannot be upgraded. Users must manage app installations manually through Ledger Live.

Is the storage used for storing transaction history?Transaction history is not stored on the device. The Ledger Nano X only stores public and private key information securely. Transaction records are retrieved from blockchain explorers via connected wallets like Ledger Live.

What happens when the device runs out of storage space?When storage is full, users must delete existing apps to install new ones. This process is managed through the Ledger Live interface, which provides a clear overview of current app usage and available space.
