Ledger Concludes Software Updates for Nano S Wallet: Technical Constraints Cited
Ledger has officially announced the cessation of software updates for its pioneering Nano S hardware wallet, a decision driven by technical constraints that limit further advancements. Introduced in 2016, the Nano S will continue to support fundamental operations, but users should not anticipate any new updates or features.
The Transition from a Legacy Device
This move signifies a complete shift from a device that was once central to Ledger’s consumer hardware offerings. In a series of posts on X, Charles Guillemet, Ledger’s Chief Technology Officer, elaborated on the reasons for this decision. According to Guillemet, the Nano S’s constrained memory capacity of 320 KB has become a significant obstacle, impeding support for contemporary applications and security enhancements.

The current memory allocation is predominantly occupied by critical components such as LedgerOS and the existing Bitcoin and Ethereum applications, leaving little room for additional functionalities.
Modern Innovations Surpass Legacy Hardware
Although Ledger officially phased out the Nano S in 2022, they continued with minimal updates for nearly two years. Guillemet highlighted that recent technological advancements in crypto wallet software, including multi-application runtimes, improved clear-signing, on-device swaps, and the Ledger Sync transaction verification, demand more memory than the Nano S can accommodate.
Despite the discontinuation of updates, Nano S users can still undertake basic tasks like sending, receiving, and swapping cryptocurrencies via key apps like Bitcoin and Ethereum. Crucially, private keys retain full portability. Ledger reassured users that they could restore their assets on newer devices by importing their 24-word recovery phrase, which is compatible with all BIP-39-compliant wallets.
In response to this transition, the company is advocating for users to migrate to the Nano S Plus, launched in 2022. This model offers enhanced memory and compatibility with the latest application features, supporting multi-app usage and adhering to evolving security standards that are now prevalent in the crypto industry.
Varied Reactions from the Cryptocurrency Community
The announcement has elicited a spectrum of reactions on X. Some users have criticized Ledger for what they perceive as planned obsolescence, suggesting that the push for upgrades pressures existing users into making new purchases. Others have voiced concerns about the potential risks associated with transferring seed phrases to new devices, particularly the threat of exposure to phishing or cyberattacks during the migration process.
However, not all industry insiders share this skepticism. Marc Zeller, a contributor to Aave, remarked that the phase-out of outdated hardware is standard practice within the technology sector. Nonetheless, he noted that Ledger could have ceased sales of the Nano S earlier to avoid confusion and set more transparent expectations for users.
“I’m not a fan of Ledger as a company, but they are decommissioning the Nano S, the older device from a decade ago, not the Nano S Plus they currently offer. Chips have a natural lifespan, and it is customary to end software maintenance of obsolete hardware after more than half a decade.”
