Ledger Discontinues Software Support for Nano S Hardware Wallet

Why did Ledger decide to discontinue software support for the Nano S?

Ledger explained that the Nano S, which was launched in 2016, only has 320KB of memory, which is not enough to meet the technical requirements of modern blockchain applications and advanced security features. According to CTO Charles Guillemet, the LedgerOS operating system and core applications such as Bitcoin, Ethereum, and exchange applications take up most of the space, leaving little room for new features such as running multiple applications simultaneously, improving clear signing, verifying transactions via Ledger Sync, or integrating DeFi protocols such as Uniswap and THORChain.

These features are seen as essential to ensure security and usability in an increasingly complex cryptocurrency ecosystem. The decision reflects a rapidly evolving technology trend where legacy devices cannot meet the needs of new applications.

Blockchain protocols are becoming increasingly complex, with the advent of DeFi applications, NFTs, and stablecoins requiring more processing power. For example, features like running multiple applications simultaneously or supporting protocols like Cardano, Polkadot, and Avalanche require much more memory than the Nano S can handle.

Additionally, security requirements have become more stringent, with features such as transparent signatures and on-device transaction verification protecting users from increasingly sophisticated cyberattacks. These changes have rendered the once-pioneering Nano S technologically obsolete.

Nano S users should note

Nano S users can still use basic functions like sending, receiving, and exchanging major cryptocurrencies like Bitcoin and Ethereum, as long as the device is still powered on and they have backed up their 24-word secret recovery phrase.

However, the lack of software updates and new app support could make the device incompatible with future blockchain protocols, limiting its ability to manage a diversified portfolio. Some users are concerned that continuing to use the Nano S without security updates will increase the risk of attacks or software bugs.

Ledger recommends that users move to newer models like the Nano S Plus, Nano X, Ledger Stax, or Ledger Flex, which have more memory and support modern features. To help with the transition, Ledger is offering a 20% upgrade discount, but this is still a disappointment for many users, especially those who invested in the Nano S early on.

Ledger stresses that Nano S users should back up their 24-word recovery phrase in a safe place, as it is the key to accessing assets on the blockchain even if the device is damaged or no longer supported. Users are encouraged to consider upgrading to newer models like the Nano S Plus or Nano X, which support more than 5,500 cryptocurrencies and are capable of running multiple applications simultaneously.

Evaluation and Conclusion

Ledger’s decision to discontinue software support for the Nano S wallet was a natural step in the rapidly evolving blockchain landscape, but it also posed significant challenges for users and the company’s reputation. With limited memory capacity, the Nano S cannot meet modern security and feature requirements, forcing Ledger to move toward newer devices. However, the negative reaction from the community highlights the need for greater transparency and support from Ledger during the transition. For Nano S users, proactively backing up recovery phrases and considering upgrades are essential to ensuring the safety of digital assets. This event not only marks the end of an era for the Nano S, but also highlights the importance of adapting to innovation in the cryptocurrency industry.
