Ledger Stax

The Ledger Stax is a battery-powered hardware wallet built around a 3.7-inch curved E Ink touchscreen. It has an ST33K1M5 secure element, connects over USB-C, Bluetooth and NFC, and charges over Qi wireless charging. Ledger announced it in 2022 and began shipping it to the first customers in 2024. It was listed at $399 on Ledger’s US shop on 14 October 2026, the highest price among the five Ledger models in our database. This page is a documentation-led review.

Ledger Stax review: who is it for?

On Ledger’s spec sheets, the main physical differences from the cheaper Ledger Flex are a larger curved screen, Qi charging, and a thinner, lighter body. The screens also differ in resolution and cover: Ledger’s comparison page lists Gorilla Glass for the Flex and lightweight durable plastic for the Stax. Security chip, battery rating, backup options and coin support are the same on both. So the Stax suits someone who values those differences enough to pay $150 more than the Flex’s $249 list price (both checked on 14 October 2026). Our Ledger Flex vs Stax page sets the two side by side.

It suits fewer people if you want:

• Fully open-source firmware. Ledger describes its code as only partly open.
• A Bitcoin-only build or Shamir (SLIP-39) backups. Ledger’s pages we checked mention neither for the Stax.
• A low price. The Nano Gen5, the lowest-priced touchscreen Ledger in our database, was listed at $179, and the USB-only Nano S Plus at $69, on the same day.

How big is the Ledger Stax screen?

Ledger lists a 3.7-inch curved E Ink touchscreen at 400 x 670 pixels with 16 levels of grey. By diagonal it is the largest screen of the five Ledger models we track; the Flex and Nano Gen5 both measure 2.8 inches. The body is 85 x 54 x 6 mm and weighs 45 g, so it is thinner and lighter than the Flex (7.7 mm, 58 g).

Ledger rates the battery at up to 10 hours of normal use or 150 transactions, the same as the Flex and Gen5. The Stax is the only one of the five that Ledger lists with Qi wireless charging, alongside USB-C.

How much does the Ledger Stax cost?

The Stax was listed at $399 on Ledger’s US shop on 14 October 2026. Ledger’s comparison page lists a Ledger Recovery Key card and a protective magnet shell in the box. Prices change, so check the maker’s shop on the day you buy.

Is the Ledger Stax secure?

The Stax keeps its keys in an ST33K1M5 secure element, the same chip part number Ledger lists for the Flex, Nano Gen5 and Nano S Plus. The Stax is a cold wallet: you prepare a transaction in an app on your phone or computer, then review and sign it on the Stax itself. Ledger’s product page says that what you see on the device screen is what you are approving.

Is the Ledger Stax open source? Partly. In a July 2024 post, Ledger says its operating system and software are “95% OpenSource and/or available” for review. That covers the companion app, the Secure SDK and the apps that run on the device. Ledger also says its agreement with STMicroelectronics legally prevents it from publishing the low-level code that talks to the secure element’s hardware. That low-level code is not publicly available for independent review.

Has the Ledger Stax had security problems? On 10 January 2025 Ledger’s security team published advisory LSB-021. It covered missing parameter validation during microcontroller firmware updates, a flaw that could permanently brick a device. The fix is in Stax firmware 1.6.2 and later, and Ledger states that client funds were never at risk.

The remaining entries in the security history below are company-level. They include a 2020 customer-data breach, the 2023 Connect Kit software supply-chain incident, and an exposure of order data through Global-e in January 2026. None of them was a seed extraction from a Ledger device. Ledger warned affected customers about phishing after the 2026 exposure. More context is in Is Ledger safe?.

How do you back up a Ledger Stax?

1. A 24-word recovery phrase. Ledger’s recovery phrase guide says its devices generate the phrase with the BIP39 standard, and that a phrase can be entered into another compatible wallet to restore access. Coin and derivation-path support on the receiving wallet still matters. See our seed phrase guide.
2. Ledger Recovery Key. Ledger’s comparison page lists it as included with the Stax. Ledger describes it as a PIN-protected backup card that stores the 24-word phrase in its own secure element chip. Ledger calls it a complement to the paper recovery sheet, not a replacement, and warns that wrong PIN attempts wipe the card’s contents.
3. Ledger Recover. This is a paid, optional subscription. It encrypts the seed’s entropy, splits it into three fragments, and gives one each to Coincover, Ledger and EscrowTech. Restoring requires identity verification with an ID document. Ledger’s Recover page says it works with the Stax through both the desktop and mobile versions of Ledger’s app.

Does the Ledger Stax support a passphrase? Yes. Ledger states that all its devices offer the passphrase option: an optional string of letters, numbers and signs that is combined with the 24 words to derive a different seed. Under BIP39 every passphrase produces a valid wallet, so a typo opens a different wallet rather than an error.

Does the Ledger Stax support Shamir backup? Ledger’s pages we checked do not state support for SLIP-39, the SatoshiLabs standard that splits a secret into shares and needs a set minimum of them to restore it.

What coins does the Ledger Stax support?

Ledger lists 500+ coins through its Ledger Wallet app, and thousands through third-party wallets. For Bitcoin multisig, Ledger says its signers have integrated multisig capabilities. That statement covers Ledger devices in general, and we did not find a list of coordinator apps confirmed for the Stax specifically.

What we could not verify

• SLIP-39 (Shamir) backup support: not stated on the Ledger pages we checked.
• A Bitcoin-only edition: none found.
• Which third-party multisig coordinators Ledger confirms for the Stax specifically.
• How the curved E Ink panel holds up over years of use: Ledger’s pages we checked give no durability rating.
• The countries Ledger ships the Stax to.
