Ledger’s Next-Generation Devices: Ledger Stax vs Ledger Flex

Ledger has always been at the forefront of digital asset security, as the first-ever signer to implement the Secure Element chip, and then drive their screens directly with that chip. This proven security model contributed to Ledger solidifying its position as the most popular signer for the last decade. 

Remember—no Ledger signer has ever been hacked!

With the launch of Ledger Stax, we raised the bar, unveiling a new signer with a secure touchscreen: the first of its kind. But Ledger Stax is a premium signer, and secure touchscreens should be accessible to everyone. To address this issue, is the next signer in that secure touchscreen category: Ledger Flex. 

Put simply, Ledger Stax and Ledger Flex are two different signers in the secure touchscreen category. Ledger Stax offers a more premium option while Ledger Flex offers similar features at an attractive price point.  

But there’s a bit more to it than that. Let’s first dive into exactly what a next-generation signer is to see which features Ledger Stax and Ledger Flex share.

Ledger’s Next Generation Devices: Explained

Ledger’s next-generation signers, Ledger Flex and Ledger Stax build on the same proven security model as all Ledger signers: they feature a Secure Element chip, certified to be resistant to remote and physical hacking, a secure operating system (OS) that ensures your private keys stay encrypted, and a secure screen resistant to hacking since it’s driven directly by the secure element. 

While Ledger signers have protected private keys successfully for a decade, digital security is becoming more complex. To stay at the forefront of security, it’s necessary to evolve. Thus the key advancement of Ledger’s next-generation signers lies in their user experience and expansion beyond digital assets.

Let’s see how:

Bigger Display, Better UX

The first feature of Ledger’s next-generation signers includes their bigger display with an improved user experience. To explain, a large portion of crypto heists are carried out via malicious approvals or transactions. These attacks pose a significant threat when the screens of most hardware wallets are too small to review transaction details easily. The risk also intensifies the more complex the transaction is.

With a larger and clearer display, Ledger Stax and Ledger Flex let you read and review transaction details clearly, offering a more intuitive experience, akin to a smartphone. This more familiar user experience reduces the risk of errors or misunderstandings. 

The World’s First Secure Touchscreens

The issue with smartphones and laptops is that their screens are vulnerable to malware. The screen of your laptop or smartphone is built for performance, not security. Driving a screen with an insecure chip such as a general-purpose Microcontroller Unit (MCU) chip, leaves it vulnerable to spoofing. Simply, you can’t trust the details it shows.

Ledger Flex and Ledger Stax offer the world’s first-ever Secure E-Ink Touchscreens, driven directly by the Secure Element chip. The Secure Element chip, also used in bank cards and biometric passports, is tamper-proof: resistant to physical and remote attacks. 

This allows you to verify transaction details on your Ledger Flex or Ledger Stax signer’s secure touchscreen with confidence. This also allows you to avoid falling for malware on your internet-connected device. Verifying a transaction’s details are the same on both your Ledger signer and smartphone or laptop can help you verify a transaction’s details are authentic.

Expanding Your Digital Security Beyond Assets

As more of our lives center around the online sphere, it’s becoming increasingly important to take digital security seriously. Generating and managing passwords for your online accounts is not as simple as it seems. Your passwords must be strong enough that no attacker could guess them, and you must have a unique password for each account. Password managers have been the most convenient solution to this problem, but these services aren’t equipped to handle modern attacks and, today, data breaches are still common.

Instead of using password managers, you can do away with passwords by logging into your favorite platforms and apps using a security key. The Ledger Security Key app transforms your Ledger Stax and Ledger Flex into a Passkey, allowing you to do away with passwords and mitigate phishing risks. The app is compatible with countless apps and platforms, from Coinbase to Google, allowing you to log in with a simple tap via your Ledger Flex or Ledger Stax signer’s NFC. 

Moreover, the Ledger Security Key app allows you to use your Ledger signer for Two-Factor Authentication (2FA), reducing the risk of unauthorized access.

Meet Ledger’s Next Generation Devices

Ledger Stax: The World’s First Secure E Ink Touchscreen

Ledger Stax is a premium signer designed by Tony Fadell. It is a signer of multiple firsts—the world’s first secure touchscreen, the first-ever curved E Ink touchscreen, and the first organic TFT screen brought to mass production.

The curved E Ink touchscreen of Ledger Stax lets you personalize the lock screen with any image you like, such as your favorite NFT, meme, or photo—which will stay visible even on standby mode. The curved screen also allows you to name the spine, for easy identification if you have multiple signers. Ledger Stax signers also feature embedded magnets, making them stackable.

Ledger Stax also supports Bluetooth and NFC, providing versatile connectivity options for both desktop and mobile platforms. Moreover, the Ledger Stax comes with wireless Qi charging.

Ledger Flex: The New Standard for Ledger Devices

Ledger Flex represents the new standard for Ledger signers. Ledger Flex features a secure E Ink touchscreen and intuitive user experience—just like Ledger Stax—but at an attractive price point. 

Its 2.8” E Ink touchscreen, which is flat rather than curved, benefits from the secure touchscreen technology introduced with Ledger Stax. The screen of Ledger Flex allows you to read transaction details clearly and offers a comparable user experience to Ledger Stax. It also supports both Bluetooth and NFC, enabling seamless connectivity with a range of signers, including desktops, smartphones, and tablets.

Ledger Flex also allows you to customize its E Ink touchscreen, with the choice to set the lock screen to whichever image, NFT, or digital art piece you like. Put simply, secure touchscreens should be accessible to everyone, and Ledger Flex is the entry-level signer in Ledger’s new secure touchscreen category.

Ledger Stax Vs Ledger Flex: Ledger: Which Device Should I Choose?

Whether you choose Ledger Flex or Ledger Stax, you’ll benefit from Ledger’s proven security model, plus the UX improvements of the next generation of devices including their secure touchscreens, bigger and better screens, and Ledger Security Key app capabilities. Plus, both Ledger Flex and Ledger Stax offer Bluetooth, and customizable lock screens, allowing you to display your favorite image or NFT.

However, there are some key differences to note. 

The 3.7”, curved E Ink touchscreen of Ledger Stax allows you to customize the spine as well as the lock screen. It’s the signer for users who want to manage multiple signers, as it lets you stack multiple Ledger Stax signers with its in-built magnets. Ledger Stax is a premium signer that offers Wireless Qi charging, retailing at $399.

The secure E Ink touchscreen of Ledger Flex is smaller than the one on Ledger Stax (at 2.8”) and is flat rather than curved, meaning only its lock screen is customizable. The built-in magnets of Ledger Flex also have a different role, reserved for attaching handy screen protectors and accessories rather than stacking multiple signers. Unlike Ledger Stax, it doesn’t offer Wireless Qi charging. The final difference lies in the price, as Ledger Flex retails at $249.

Ledger: This Is What Security Feels Like.

No matter which signer you choose Ledger Stax or Ledger Flex—or even a Ledger Nano X or Ledger Nano S Plus, you can rest assured you benefit from Ledger’s proven security model. 

Ledger’s next-generation signers, Ledger Flex and Ledger Stax represent the new standard of hardware security, offering secure touchscreens that you can trust and a more familiar user experience than ever before. 

So what are you waiting for? Protect your digital assets and accounts from online threats and get peace of mind. Get a secure touchscreen signer!

The Shift: From Hardware Wallet to signer 

Crypto may have begun as a bold experiment, but adoption has grown as the technology and user experience have rapidly evolved; the language used to describe it, has however, stayed stuck in its infancy.

We called our devices “hardware wallets,” mislabelling the role of secure hardware, and obfuscating the role of software (Ledger Live). Along the way, users were left behind.

People believed:

• That value was stored on the device (it isn’t).
• That if you lose the device, you lose your assets (you don’t).
• That the device itself was the endgame (it’s not).
• That those 24 words were a burden only tech-savvy users could manage (not true anymore).

These are more than misconceptions. They are adoption blockers. So at Ledger, we believe that clarity is essential for the next stage of adoption

We’re changing how we speak about our products. And by doing so, we’re changing how people understand digital ownership itself.

Hardware wallets  → signers

Ledger devices don’t store value. They sign transactions. They prove intent. They verify identity. They’re not vaults, they’re the secure bridge between who you are and what you do online. They don’t just hold keys. They empower you to trust yourself.

We call them signers now, because that’s what they truly are.

In a world where AI grows more powerful every day, proof of humanity matters more than ever. A signer is more than a security device, it’s your cryptographic proof of you. It gives you a secure foundation to own, authorize, and protect your digital life without relying on anyone else. From sending a transaction to signing a contract or verifying your credentials, your signer  ensures you, and only, can provide digital consent – proof of you.Together, signer and Ledger Wallet redefine what digital ownership looks like, clear, secure, and free from compromise.
