KEY TAKEAWAYS:
  • Decentralized applications are secure due to their lack of third-party control. However, they face challenges when required to securely share data with other applications or other instances of the same application.
  • Due to that, the only way to Sync your Ledger Live™ applications on both your smartphone and your laptop previously, was to scan a QR code—an inconvenient method for our increasingly digital lives.
  • Ledger Sync, an optional feature built upon Ledger Key Ring Protocol, allows you to effortlessly sync your accounts in Ledger Live—safely, securely, and with complete privacy.

There’s a good chance that you already use a few online applications with account synchronization. Whether it’s for listening to your favorite music streamer, logging onto social media, or answering your emails, the experience of using all our favorite applications on all our different devices is one we’ve come to take for granted

While the data sharing that makes this account synchronization possible is commonplace in Web2 applications, implementing a similar solution for decentralized apps while maintaining the same privacy is more challenging. 

This is also true for Ledger Live, meaning synchronization of your data on both your phone and laptop was previously inconvenient. 

But we solved the problem!

Thanks to Ledger Sync, a feature that relies on Ledger Key Ring Protocol, Ledger Live users can enjoy a seamless experience, with easy access to all their Ledger Live data across multiple devices. 

With Ledger Sync you can effortlessly sync your accounts in Ledger Live—safely, securely, and with complete privacy.

Let’s see how it works.

What is Ledger Sync

Ledger Sync is an optional service 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. 

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.

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.

The foundation's participation as a sponsor at Consensus 2025 in Toronto and Digital Assets Week in New York demonstrates its commitment to engaging with builders, investors, and institutional leaders across the blockchain space.

These events serve as crucial networking opportunities and platforms for showcasing innovative projects within the Stellar ecosystem. Recent Meridian events have highlighted creative projects like Skyhitz and HoneyCoin, illustrating the collaborative spirit and diverse applications being built on the platform.

Real-World Impact in Emerging Markets

Perhaps most importantly, Stellar's growth isn't just about technical metrics—it's about real-world impact. The platform's focus on emerging markets addresses genuine financial inclusion challenges, providing efficient payment rails and access to digital financial services where traditional banking infrastructure may be limited.

This practical approach to blockchain implementation sets Stellar apart from projects that focus primarily on speculative trading or theoretical use cases. By solving actual problems for real users, Stellar is building sustainable demand for its technology.

Looking Ahead: Enterprise-Grade Infrastructure

Stellar positions itself as offering enterprise-grade asset tokenization alongside its DeFi capabilities and payment infrastructure. This comprehensive approach makes it attractive to institutions looking for a single platform that can handle multiple blockchain use cases.

The combination of fast transactions, low costs, smart contract capabilities, and regulatory-conscious development creates a compelling value proposition for enterprises considering blockchain adoption.

The Road Forward

As 2025 progresses, Stellar's ecosystem appears well-positioned for continued growth. The technical infrastructure improvements, developer-focused enhancements, and real-world adoption initiatives create a strong foundation for expanding use cases and user adoption.

The blockchain industry has seen many projects promise revolutionary capabilities, but Stellar's focus on delivering measurable performance improvements and practical solutions suggests a mature approach to blockchain development. With transaction speeds that rival traditional payment systems and growing institutional adoption, Stellar is demonstrating that blockchain technology can move beyond experimental phases into mainstream utility.

For developers, institutions, and users looking for blockchain solutions that prioritize both performance and practical applicability, Stellar's 2025 developments represent significant progress toward a more accessible and useful decentralized financial ecosystem.

What's New in 2025: Enhanced Audit Support for Soroban Builders

Teams building financial protocols, high-dependency data services, high-traction dApps funded by the Stellar Community Fund are able to request an audit and will typically be matched with a reputable audit firm within two weeks. We recently restructured the program for this year to enhance audit efficiency and incentivize accountability, and rapid and complete vulnerability remediation:

  • Complimentary Initial Audit: Projects will need to contribute 5% of the audit cost upfront, but this co-payment amount is eligible for a full refund, provided that critical, high, and medium vulnerabilities identified are swiftly remediated within 20 business days of receiving the initial audit report (learn more).
  • Incentivized Security at Key Traction Milestones: Complimentary, extensive follow-up audits are available as projects achieve critical traction milestones (e.g., $10M and $100M TVL). These audits include deeper assessments such as formal verification or competitive audits, significantly boosting project security at pivotal stages.
  • Advanced Security Tooling: Projects can enhance their security self-serve through complimentary or discounted access to specialized tooling, which provide vulnerability detection and formal verification capabilities (see full list of available tooling). These tools are encouraged to capture ‘easy-to-spot’ issues prior to audit as well as a final check post-audit to increase the effectiveness and thoroughness of audits.
  • Enhanced Audit Readiness Support: Projects receive structured preparation support, including the implementation of best practices and security standards based on the STRIDE threat modeling framework. This ensures project teams are thoroughly prepared, optimizing audit efficiency and minimizing delays.

Santander mulls stablecoin, crypto offering

Bloomberg reported that Banco Santander is mulling introducing euro and dollar stablecoins, or potentially making a third party coin available to clients, citing sources. This move aligns with broader crypto ambitions, as its digital bank, Openbank, has reportedly applied for a European cryptocurrency license under the Mica Regulations and may enable retail access to digital assets.

Systemically important banks embrace stablecoins?

Major banks are now moving from observers to participants in this expanding market. Should Santander confirm plans to launch a stablecoin, it will be the fourth global systemically important bank (G-SIB) to do so. Societe Generale’s FORGE subsidiary launched the EURCV euro coin in 2023. Deutsche Bank is a partner in ALLUnity, another stablecoin initiative with plans to launch this year, subject to regulatory approval. And Standard Chartered is part of a joint venture in Hong Kong that intends to introduce a stablecoin.

Santander’s involvement could extend beyond an individual initiative. The bank is a shareholder in The Clearing House, where the Wall Street Journal reported that US banks are exploring the potential to create a joint stablecoin. If a US initiative took that route it could involve nine more G-SIBs including Bank of America, Barclays, BMO, BNY Mellon, Citi, HSBC, JP Morgan, TD Bank and Wells Fargo.

Apart from these initiatives, our research shows that more than 20 other banks have been involved in stablecoin projects.

Until recently stablecoins were mainly used to settle cryptocurrency transactions and by residents in countries with volatile domestic currencies. During the last year stablecoin infrastructure has been expanding, especially for mainstream cross border payments. Plus, President Trump issued an executive order prioritizing stablecoins. One of the administration’s motivations is this increases demand for US Treasuries, lowering the interest rate the government pays on the Treasury bills.

Santander as an early digital assets mover

Santander’s stablecoin consideration builds on years of blockchain experience. The bank was an early Ripple investor and previously used Ripple’s permissioned network for payments (not XRP), while also embracing permissionless blockchain activities including issuing a digital bond on Ethereum in 2019. This dual approach led to collaborations with other major players – alongside Societe Generale FORGE and Goldman Sachs, Santander participated in the European Investment Bank’s first digital bond, also on Ethereum. Currently, the bank’s most significant digital money initiative involves Fnality, the wholesale blockchain-based settlement network, where Santander ranks among 20 institutional backers and is part of the early adopter group alongside Lloyds Bank and UBS.
