Introduction

Harmony (ONE) is a high-speed, sharded blockchain designed for decentralized applications and cross-chain interoperability. While Ledger Live does not natively support Harmony (ONE), you can securely store and manage your ONE tokens by connecting your Ledger hardware wallet to the Harmony Wallet Chrome Extension or Math Wallet.

This guide will walk you through the steps to safely store, stake, send, and receive ONE using your Ledger device.
