- Ledger has officially ended software support for its popular Nano S hardware wallet, citing memory limitations that prevent modern crypto apps and security upgrades.
- Users are divided, with some accusing Ledger of forcing upgrades, while others accept the phase-out as standard practice in tech.
PARIS, (MarketsXplora) – Ledger, the French-based hardware wallet manufacturer, is officially ending software support and updates for its long-standing Nano S device, a move that has stirred a mix of frustration, concern, and resignation among users across the cryptocurrency community.
Originally launched in 2016, the Ledger Nano S became the company’s first breakout success in the consumer crypto market. However, the device’s limited 320 KB memory has become a constraint in the face of rapidly evolving blockchain technology. Ledger’s Chief Technology Officer Charles Guillemet took to social media platform X to explain that the device could no longer accommodate modern crypto apps or essential security enhancements.
“LedgerOS, Bitcoin, Ethereum, and exchange apps already consume nearly all available space,” Guillemet said. “There is very little room for anything else.” He added that this limitation prevents the Nano S from supporting key features like multi-app runtimes, advanced clear-signing, Ledger Sync transaction verification, and on-device swaps via protocols such as Uniswap.
Is Ledger Nano S Still Safe to Use Without Updates?
While the Nano S remains technically functional for core crypto activities—including sending, receiving, and swapping Bitcoin and Ethereum—Ledger warned users that the lack of ongoing updates means the device may soon fall behind contemporary standards of usability and, more critically, security.
Ledger had formally retired the Nano S in 2022, but continued to provide limited software support—until now. In its Spring 2025 update, the company confirmed it has halted manufacturing and will no longer accept new app submissions or updates for the device.
Ledger is urging users and developers to transition to more capable models like the Nano S Plus, introduced in April 2022, or the higher-end Nano X.
“We recommend you begin planning for this transition now to ensure continuity for the users,” Ledger stated in its developer communication. The message was clear: while the Nano S had served its purpose, its limitations now pose a barrier to innovation and user safety.
Not everyone views the decision as unreasonable. Aave contributor Marc Zeller commented that hardware deprecation is a standard practice in tech, noting that “chips have a natural lifespan.” However, he suggested that Ledger could have acted sooner to halt sales of the Nano S to better manage user expectations.
Community Divided Over Transition
Despite Ledger’s technical reasoning, the decision ignited backlash on platforms like X, where users accused the company of coercing them into hardware upgrades.
“Very uncool Ledger – you effectively force anyone to buy and enter the seed into a new device,” wrote a user under the handle Pcaversaccio, who identified as working within the Ethereum ecosystem. He added that while he understood the business rationale, he urged Ledger not to compromise backward compatibility, warning that many still rely on the Nano S as a trusted cold wallet.
Other users echoed the sentiment, with some expressing hope that open-source developers would create alternatives to keep the Nano S functional. “Am I reading this right? Ledger is just gonna deprecate people’s existing devices and force them to buy the new one? WTF?” one user asked.
The debate also touched on security concerns. Some users questioned whether the Nano S would remain safe to use without further updates. “It will probably still work,” commented Beau, a safety project manager for Pudgy Penguins. “But the device won’t be receiving updates, meaning it’s more likely to break or have a security issue.”
Still, some, like Tornado Cash developer Roman Semenov, downplayed the need for regular updates.
“I stopped updating my Ledger years ago when they started to roll out their cloud backup firmware feature,” he said. “It doesn’t really need any updates to work.”
Coinciding with the end-of-support announcement, Ledger introduced a physical Recovery Key for its users—an emergency tool designed to help quickly regain access to wallets in case of device loss or failure. The rollout underscores Ledger’s shift toward more modern and robust wallet infrastructure, reinforcing the message that continued reliance on older devices like the Nano S may no longer be sustainable.
