Nano S devices already in use will still function, but future compatibility with apps and protocols is not guaranteed.
Ledger has advised all Nano S owners to ensure they have securely backed up their 24-word Secret Recovery Phrase.
The decision to discontinue the Nano S hardware wallet has been met with serious criticism.

In a move that has stirred debate across the crypto community, Ledger has announced it will discontinue its long-standing Nano S hardware wallet.

The announcement, made as part of Ledger’s Spring 2025 update, marks the end of an era for one of the most widely used crypto security devices launched in 2016.

Nano S has reached its technical limits

Ledger stated that the Nano S hardware has reached its technical limits, making it increasingly difficult to support modern blockchain applications and advanced security features.

According to the company, the device’s limited flash memory and RAM have become a major constraint in today’s evolving crypto environment.

The Nano S was originally equipped with a Secure Element chip (ST31H320) offering 320 KB of flash memory, which was sufficient at the time of release.

However, Ledger now says that memory is no longer enough to support features such as Clear Signing, Ledger Recover, NFT transfers, swaps through THORChain and Uniswap, or even multiple apps running simultaneously.

The company emphasised that while the Nano S is still usable, it will no longer receive firmware updates, security patches, or new app support.

Ledger wants Nano S users to upgrade

Ledger is urging its customers to transition to newer models such as the Nano S Plus, Nano X, Ledger Stax, or the recently introduced Ledger Flex.

The company maintains that upgraded devices come with more storage, enhanced usability, and compatibility with upcoming blockchain technologies.

Ledger also introduced the Ledger Recovery Key, a new offline tool for private key recovery that works without internet or cloud services.

This innovation allows users to store their keys securely on a smart card protected by a PIN and accessible via NFC, while avoiding the identity verification process that drew criticism for its predecessor, Ledger Recover.

Despite these additions, the transition away from Nano S has not been smooth in the eyes of many long-time users.

Backlash over the forced migration

Numerous crypto users have expressed disappointment and anger over what they describe as an abrupt and unnecessary discontinuation.

On platforms like X (formerly Twitter), users argue that the Nano S remains functional and accuse Ledger of pushing forced upgrades that compromise trust.

One user, @BAYC5511, called Ledger “absolutely worthless,” criticising the company for disregarding customers who bought Nano S devices during the 2021–2023 bull run.

What in the fuck is this @Ledger why are you discontinuing support for the nano s? Im pretty sure a large amount of the 2021-2023 people use this device as their primary hardware wallet. Absolutely worthless company, will never buy another ledger product again. https://t.co/cOAjuY0n3l

Another user, @STRYED0R, pointed out that the memory limitations have always existed and are not a valid reason for ending support now.

“the hardware has reached the limits of what it can support. The device’s memory capacity restricts the number of apps that can be installed at once, which makes it difficult to manage multiple assets or blockchains.”
THIS HAS ALWAYS BEEN THE CASE!

NOT A PROPER REASON.

These sentiments reflect a broader concern that Ledger is abandoning backward compatibility, thereby risking the trust it spent years building.

Ledger has defended its decision

In response to the backlash, Ledger has reiterated that the Nano S reached end-of-life status back in 2022, and this final phase-out was part of a long-communicated transition.

The company clarified that the Nano S Plus, which retains the same form factor but includes more memory and ongoing support, remains fully operational.

To ease the shift, Ledger is offering a 20% discount for users upgrading from the Nano S to a newer device.

Despite this gesture, many users have called for free replacements, claiming that security should not come at an extra cost for early adopters.
