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 Wallet™ (previously known as 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 Wallet—without compromising privacy.

Enter Ledger Sync, powered by Ledger’s Key Ring Protocol. It allows you to securely sync your Ledger Wallet 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 Wallet users to sync instances of Ledger Wallet across multiple devices. 

In other words, you can now activate the feature to synchronize the Ledger Wallet application on your desktop and the Ledger Wallet app on your mobile device every 10 seconds. This allows for a more user-friendly experience, perfect for those who use Ledger Wallet 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 Wallet (previously known as Ledger Live) on your new signer and connect your wallet to access your Ledger Wallet 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 signer, and it’s these keys that encrypt your Ledger Wallet 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 (Ledger signer™) 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 Wallet 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 signer 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 Wallet. Essentially, it allows separate instances of Ledger Wallet (for example, Ledger Wallet on your desktop and Ledger Wallet 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 Wallet data stays private and within your control.

Why Ledger Sync is Essential to Ledger Live

Ledger Wallet 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 signer so your private keys never leave the hardware.

Ledger Sync helps you keep real-time track of your transactions on your Ledger Wallet 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 signer. 

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 Wallet is more convenient than ever. No matter which device you use, either your smartphone or laptop, your Ledger Wallet 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 signer is good for you.

The Shift: From Ledger Live to Ledger Wallet

Crypto may have begun as a bold experiment, but adoption has grown as the technology and user experience have rapidly evolved; the language used to describe it, has however, stayed stuck in its infancy.

Ledger Live → Ledger Wallet app™

Ledger Live has evolved far beyond a simple portfolio tracker. It’s now the place where people buy, sell, stake, swap, send, and receive, across chains, with clarity and confidence. It’s where secure interactions meet meaningful opportunities.

But to make Ledger Wallet fully immersive we’ve added a key missing piece of the user journey. You can now effortlessly top-up with fiat from your bank, instantly converting to stablecoin, for free, no need for that extra CEX hurdle. 

• More Cost-Effective & Efficient Funding: Top up your crypto wallet directly, bypassing exchanges, so you can seamlessly buy, swap, and stake your digital assets.
• Effortless & Secure Access: Get started quickly with a simple, secure solution designed for your convenience.
• Make Ledger Wallet your go-to money app: Receive your paycheck & start earning or spending with your stablecoins.

This is the new era of digital ownership. Total control over your digital value.

That’s why we now call it Ledger Wallet. Because it’s not just a companion to your device. It’s the place where you connect, convert, transact, and step into everything that lives on-chain.

In short, Ledger Wallet offers the best software experience; but you still need a device that gives you the confidence and clarity to securely sign all the transactions with total peace of mind. You need a signer.
