When people think of Ledger hardware wallets, they often focus on the secure storage of private keys. But there’s another critical component of security that’s often overlooked: the screen.

Why the screen matters

In the world of crypto, even the slightest mistake during a transaction can lead to irreversible loss of funds. If your computer or phone is infected with malware, hackers can tamper with transaction details shown on external apps — without you knowing.

That’s why Ledger ensures that all important transaction data is displayed directly on the device screen, allowing users to verify and approve with confidence and to prevent tampering by malware on connected devices. This concept is known as a Secure Screen.

What is Secure Screen?

Secure Screen is a feature that ensures transaction details — like the amount and recipient address — are shown only on the device itself, not just in the app. This prevents users from unknowingly approving malicious or manipulated transactions.

Enter E Ink® Technology – Featured in Ledger Stax

Ledger’s latest model, Ledger Stax, is equipped with an innovative E Ink® touchscreen, offering a sleek, smartphone-like experience while maintaining maximum security. This screen is energy-efficient, glare-resistant, and provides tamper-proof display of your transaction data.

Even if your device is connected to a compromised computer or phone, the information you see on your Ledger’s screen is fully secure and verifiable.

“What You See Is What You Sign”

This phrase is central to Ledger’s security philosophy. It means that whatever you see on your device screen is exactly what you’re approving. If anything looks off — like the recipient address or amount — you can cancel the transaction immediately, protecting your assets from potential scams or hacks.
