" Ledger Nano S is a secure Bitcoin and Ethereum hardware wallet. It connects to any computer through USB and embeds a built-in OLED display to double-check and confirm each transaction with a single tap on its buttons.
MULTI-CURRENCY
Nano S supports Bitcoin and Ethereum blockchains: hold different assets and spend them from the same hardware wallet.
SECURE DISPLAY
Check transactions on the OLED display and confirm using the physical buttons (anti-malware second factor).
SECURITY
Your private keys are secured inside a strongly isolated environment locked by a PIN code, and are never exposed.
SIMPLICITY
Get started in few minutes: simply connect your Ledger Nano S to any computer, and you are ready to use it.
MULTI-APPS
In addition to Ethereum and Bitcoin wallets, use third party apps such as FIDO U2F, GPG, SSH or build your own.
BACKUP & RESTORATION
Your Nano S accounts are backed up on a paper wallet. Easy recovery on any Ledger device or compatible wallet (BIP39/BIP44).
Security
SECURE ELEMENT
Ledger Nano S is based on a dual chip architecture (ST31/STM32). The firmware integrity is guaranteed by cryptographic attestation.
PIN CODE
Ledger Nano S ensures only you can access your accounts by requiring a 4 digit PIN code each time it is plugged to your computer.
MALWARE PROOF
Even on a compromised computer, you can initialize your Nano S and confirm each transaction on the built-in display, protecting your assets against malware, theft or viruses.
PRIVACY
Your private keys are never held or known by Ledger or a third party: they are hard locked in the Secure Element. With Ledger Nano S, your wallet remains decentralized, you are your own bank. "
