Do firmware updates or derivation paths change which address my hardware wallet owns

07 September 2026

No, a firmware update does not change which addresses your hardware wallet controls. A derivation path change does, but only because you are then asking the device to manage a different set of keys.

The address your hardware wallet "owns" is determined by a single seed phrase, which is generated once during initial setup and stored in the device's secure element. Firmware updates modify the software that runs on the device - fixing bugs, adding coin support, or changing the user interface - but they never alter the seed. The seed is isolated from the firmware by the hardware's architecture. Updating firmware is like reinstalling the operating system on a computer without touching the files on the hard drive. Your addresses remain exactly the same after an update.

Derivation paths are a different matter. A hardware wallet does not control a single address; it controls an entire tree of addresses, each derived from the seed via a specific path. The path is a set of numbers that tells the wallet which branch of the tree to walk down. Change the path, and you walk down a different branch. The keys on that branch are still derived from the same seed, but the addresses are different. For example, the path m/44'/0'/0'/0/0 yields a different address than m/44'/0'/1'/0/0. Both are owned by the same hardware wallet - both can be signed for with the same device - but they are distinct addresses.

This matters in practice because many software wallets and exchange interfaces let you choose a derivation path. If you select a non-standard path, your hardware wallet will still sign for that address, but other wallets may not recognize it as belonging to your device. The address is still yours; it is just hidden from view unless you know the path.

A firmware update does not reset or scramble the derivation path. The device continues to use whatever path the software instructs it to use. If you used path A before the update, you will use path A after the update, unless you manually change the path in the wallet software.

If you are moving assets from a hardware wallet - for instance, during a swap that involves Monero - you need to be sure you are sending from the correct address. A firmware update will not cause you to lose access to that address. A mistaken derivation path can. The safest practice is to verify the address on the device screen before sending any transaction. That verification confirms the address belongs to the seed in that specific device, regardless of what path was used to derive it.

The hub page for this set covers how to swap Monero from a Ledger without exposing the view key. That process relies on knowing exactly which addresses your device controls. Understanding that firmware updates are harmless and derivation paths are deliberate choices is prerequisite to executing such a swap safely. If you are unsure which path your wallet uses, check the wallet's settings before starting the swap. Changing the path mid-swap would send funds to an address your device controls but that your wallet software may no longer display.

In short: firmware updates are safe. Derivation paths are not dangerous, but they are specific. If you pick the wrong path, the address still belongs to your device - you just have to know the path to find it again.
