WALLET-LEDGER stores your private keys in an isolated chip and signs transactions offline. Even a compromised computer can't reach them.
Every transaction is signed inside the device — the private key can never physically leave the chip.
A 24-word recovery phrase is created by a random number generator inside the secure element and never leaves the device.
Transaction details appear on the device's own screen. Confirmation is a physical button press, not a click in a browser.
The companion app broadcasts the already-signed transaction. The private key stays exactly where it was.
None of them rely on "trust" — only on physics and cryptography.
The same class of chip used in passports and bank cards. Physically hardened against tampering and analysis.
The key never leaves the chip, even during signing — the operation happens entirely inside an isolated environment.
The recipient address and amount are shown on the device's screen — malware on your computer can't swap them unnoticed.
Firmware code is public and verifiable by independent auditors — no hidden backdoors.
The recovery phrase is generated and displayed exclusively on the WALLET-LEDGER screen — it never passes through a computer, app, or server.
