Ledger Responds to Phasing Out Nano S: Limited Memory Makes It Challenging to Support New Features and Security Enhancements

BlockBeats News, June 27th, Ledger's Chief Technology Officer Charles Guillemet stated on the X platform that the Nano S currently has 320kb of memory, which makes it difficult to support new applications, feature submissions, and updates. Only LedgerOS, Bitcoin, Ethereum, and exchange applications almost fill up the memory, making it unable to support multi-application concurrency, Transparent Signature Improvements, transaction checks with Ledger Sync™, exchanges (such as interacting with THORChain), device language packs, and other new features and security enhancements. In a complex cryptographic environment, these features are crucial for improving clarity, usability, and security and require stronger hardware support.

Guillemet emphasized that existing Nano S users, if their device is functioning normally and their seed phrase is backed up, their assets will remain secure and accessible, and basic operations for BTC/ETH and other mainstream currencies (send/receive/transactions) will not be affected. However, upgrading to a new device will provide more comprehensive application support, future new features, and the best security experience.

In yesterday's news, Ledger's upcoming phase-out of the Nano S sparked user dissatisfaction, with questions raised about forcing users to purchase new devices.
