Ledger Sync: Sync Accounts Privately with Complete Security

Web2 apps which freely share user data across platforms can require manual steps like scanning QR codes etc, but decentralized apps (dapps) like Ledger Live prioritize privacy and security, making seamless synchronization more complex.

Think about how easy it is to pick up a playlist where you left off, check emails, or scroll through social media—your data is instantly available across devices. That’s thanks to centralized data sharing in Web2.

We wanted to bring that same convenience to Ledger Live—without compromising privacy.

Enter Ledger Sync, powered by Ledger’s Key Ring Protocol. It allows you to securely sync your Ledger Live data across devices, while keeping everything private and decentralized.

Let’s see how it works.

What is Ledger Sync? 

Ledger Sync is an add-on feature in the Ledger ecosystem that provides a simple and secure way for Ledger Live users to sync instances of Ledger Live across multiple devices. 

In other words, you can now activate the feature to synchronize the Ledger Live application on your desktop and the Ledger Live app on your mobile device every 10 seconds. This allows for a more user-friendly experience, perfect for those who use Ledger Live on multiple devices such as a smartphone and laptop.

Besides that, Ledger Sync also lets you backup account data. In fact, it’s the world’s first secure and private backup solution that doesn’t require an email and password! This offers peace of mind if your laptop or smartphone gets lost or damaged. Simply set up your Ledger Live on your new device and connect your wallet to access your Ledger Live data immediately.

How Ledger Sync Works

Maintaining privacy on decentralized networks is an inherent challenge. This is particularly apparent in the case of data sharing, which is necessary for a service like Ledger Sync to operate.

To combat this challenge, Ledger Sync uses the Ledger Key Ring Protocol to generate encryption keys from the security of your device, and it’s these keys that encrypt your Ledger Live data. Once the data is encrypted, it’s safe to be sent via public channels. Absolutely no one except the owner of the hardware wallet can encrypt that information — not even Ledger! 

The only way to restore the encryption keys—and the data they encrypt—is via a device set up with the same secret recovery phrase as the one you initiated the Sync from.

Note: Ledger Sync is designed to sync the Ledger Live app across your devices (like your phone and laptop)—not to sync or manage multiple Ledger hardware wallets. If you’re looking to manage multiple wallets, check out the different ways you can segregate your crypto assets—this article will help you get a lot of new ideas and ways to do so.

Ledger Key Ring Protocol: How it enables Ledger Sync

Ledger Key Ring protocol enables multiple applications or multiple instances of the same application to access shared information, using your Ledger hardware wallet as a central point for end-to-end encryption. It’s a protocol Ledger developed for use in multiple applications far beyond the Ledger Ecosystem. To learn more about Ledger Key Ring Protocol, make sure you read Ledger CTO Charles Guillemet’s blog post and the Ledger Key Ring Protocol whitepaper.

However, in the case of Ledger Sync, the Ledger Key Ring Protocol enables multiple instances of the same application: Ledger Live. Essentially, it allows separate instances of Ledger Live (for example, Ledger Live on your desktop and Ledger Live on your mobile device) to share data without revealing it to other parties—even when it’s shared over public networks. This means your Ledger Live data stays private and within your control.

Why Ledger Sync is Essential to Ledger Live

Ledger Live is your all-in-one crypto hub: it helps sync and recover accounts across every blockchain, buy or sell over 15,000+ cryptocurrencies via trusted partners, swap tokens at optimized rates (including cross-chain), schedule recurring buys, stake on networks like Ethereum and Cosmos, lend or borrow with integrated DeFi apps, access a curated dApp library, view and transfer NFTs (and actually display them on your Ledger Flex or Stax), track your portfolio with real-time charts, price alerts and full transaction history, and get push notifications—all secured by clear-signing on your Ledger device so your private keys never leave the hardware.

Ledger Sync helps you keep real-time track of your transactions on your Ledger Live app across devices. This means you don’t need to worry about losing track of which transactions you’ve signed or where you left off on another device. 

Whether you’re on desktop, mobile, or tablet, your account balances and history stay up to date everywhere. That way, you can pick up right where you left off—no manual exports, QR scans, or re-adding accounts required! 

Ledger Sync: An Improved User Experience for Ledger Live

Ledger Key Ring Protocol is a major development that promises increased functionality and ease of use, not just for Ledger users, but for Web3 users as a whole. And Ledger Sync is just the first service to benefit from that.

Thanks to Ledger Sync, Ledger Live is more convenient than ever. No matter which device you use, either your smartphone or laptop, your Ledger Live will show the same information, making it secure, efficient, and easy to use — without compromising your privacy.

So what are you waiting for? Join the Ledger ecosystem today and take advantage of everything that the world of secure crypto self-custody has to offer.

However, please note that the Ledger Sync service is not supported on Ledger Nano S devices. This is solely because it lacks the technical capacity to run advanced apps, including the Cardano app, and other more recent cryptographic functionalities. 

If you’re using a Nano S, you can still manually add your accounts one by one, but to access these new features, here’s a list of reasons why upgrading to a newer device is good for you.
