Introduction
The Ledger Hardware Wallet is the cornerstone of cryptocurrency security. Designed for both individuals and developers, Ledger devices such as the Ledger Nano X and Ledger Nano S Plus provide hardware-based protection for your private keys. With the Ledger Live app, users can manage, buy, exchange, and grow their crypto securely from one interface.
Ledger hardware wallets utilize a certified secure chip (CC EAL5+) and proprietary BOLOS operating system, ensuring that sensitive information never leaves the device. Developers can use the Ledger Developer Portal to integrate with apps and extend Ledger’s ecosystem.
Why Choose Ledger Hardware Wallet?
The Ledger Hardware Wallet is trusted by millions of users worldwide. It offers advanced encryption, physical confirmation for all transactions, and secure offline storage. Unlike software wallets, Ledger ensures private keys are never exposed to the internet, eliminating the biggest attack vector for hackers.
The Ledger ecosystem integrates with hundreds of third-party apps, exchanges, and DeFi protocols. Whether you are trading on Binance, exploring NFTs, or developing your dApp, Ledger’s infrastructure supports your needs.

Security Architecture
Ledger uses a dual-chip design — a secure element chip (SE) and a microcontroller — to separate sensitive operations from external communications. BOLOS, Ledger’s proprietary OS, isolates applications and enforces strict data protection policies. This architecture is designed to prevent malware attacks, unauthorized access, and tampering.

Integration for Developers
Developers can integrate Ledger wallets into their blockchain apps using the LedgerJS SDK. The SDK allows signing transactions, managing accounts, and supporting custom coins. Ledger provides a comprehensive API and documentation through the Ledger Developer Portal.
import TransportWebUSB from "@ledgerhq/hw-transport-webusb";
import AppEth from "@ledgerhq/hw-app-eth";
const transport = await TransportWebUSB.create();
const appEth = new AppEth(transport);
const { address } = await appEth.getAddress("44'/60'/0'/0/0");
console.log(address);
