Important Update for Device App Developers:
Transitioning from Ledger Nano S™ Support
[UPDATED ON 26 JUNE, 2025]
Since its launch in 2016, the Ledger Nano S™ has been the cornerstone of self-custody and digital asset security. As the crypto landscape rapidly advances, Ledger is evolving our hardware platform to meet the demands of this dynamic ecosystem.
To ensure our users benefit from the latest features, security enhancements, and the ever-expanding crypto ecosystem, we are gradually transitioning our focus from the Ledger Nano S™. With this in mind, we’re no longer able to accept new application submissions, feature enhancements, or app updates for the Ledger Nano S™. We’re here to work with you through this transition.
Ledger Nano S™ still supports essential actions like sending, receiving, buying, selling, and swapping for BTC, ETH, and other major apps, which will remain functional for the foreseeable future. However, due to its primary memory constraint (320kb) it cannot support new applications, feature submissions, or app updates. This limitation also prevents it from storing a larger amount of applications simultaneously or supporting newer features like Clear Signing improvements, Transaction Check, Ledger Sync™, more advanced swaps (e.g., with THORChain, Uniswap, TON, ADA, NEAR, AVAX, DOT), or Device Language Packs.
What This Means for Device App Developers:
We urge you to begin planning for this transition now to ensure continuity for your users. We recommend you:
-
Inform Your Community: Proactively communicate that while their Ledger Nano S™ still works for core functionalities, due to its hardware limitations and the official retirement in 2022, continued full support for your blockchain app/wallet/service on the Nano S™ may not be guaranteed
-
Encourage Upgrades: Advise your community to consider upgrading to a newer Ledger signer (such as the Ledger Nano S Plus™, Ledger Nano X™, or Ledger Stax™) for a seamless and future-proof experience. We’re even offering 20% off to help you make the switch
- Upgrade here. -
Stress Secret Recovery Phrase Importance: Remind your users to always verify they have securely backed up their 24-word Secret Recovery Phrase. This remains the ultimate key to accessing their digital assets, regardless of their device.
-
While Ledger will no longer deploy new or updated Nano S™ apps in the Ledger Live App Catalog, developing on the Ledger Nano S™ remains technically possible using the resources available on our developer portal, which will remain up-to-date.
Ledger’s Commitment to Developers:
We are committed to supporting our developer community through this transition. Ledger will provide updated documentation, tools, and resources to help you smoothly phase out Ledger Nano S™ compatibility and optimize your applications for our latest devices. Please note that Nano S Plus remains fully supported
Important Reminder: As the developer of Device Apps, you assume complete responsibility for the functioning of your Device App and any potential damage it may cause to end-users.
