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.

⚠️ More Secret Than The Atomic Bomb ⚠️

⚠️ More Secret Than The Atomic Bomb ⚠️

A deep dive into the triangular UAP seen throughout the United States and the world for decades. With the Immaculate Constellation report, at least SOME equilateral and isosceles triangle craft have been identified as reproduction and Alien Reproduction Vehicles.

Numerous sightings and whistleblower testimony have lent evidence to the thesis DOD and private contractors have operated reverse-engineered triangular craft out of key military bases since at least the 1980s. Key testimonies here include: Edgar Fouche and the TR-3b reverse-engineered triangle, US sightings from 1980-2000, and a strange illustration of a triangular craft called the XF-131 Super Sentinel.

Was Edgar Fouche's testimony of TR-3B and Area 51 programs true? How many prototype and operational triangle ARVs have been constructed? Why did the X-Files contract the work of an allegedly real triangle ARV out of Lockheed Martin's Helendale Plant?

🚨David Grusch on The Megyn Kelly Show🚨

Earlier this week, UFO/UAP whistleblower David Grusch appeared on The Megyn Kelly Show for a brief but revealing interview. During the conversation, Grusch named individuals he claimed were involved in managing the alleged UFO/UAP Legacy crash retrieval program, statements that immediately drew attention across the disclosure community.

Most notably, Grusch asserted that former Vice President Dick Cheney played a central role in overseeing the program. Cheney’s name has circulated within UFO/UAP research circles for years, but this marks the first time it has been spoken publicly by a former intelligence official who claims direct knowledge of the issue. It is also notable that just weeks ago, journalist Ross Coulthart independently referenced Cheney in a similar context, lending additional weight to the consistency of these claims.

Grusch also named former Director of National Intelligence James Clapper, stating that Clapper was not only aware of the crash retrieval issue, but managed it and helped place individuals into key roles, both publicly and behind the scenes. These are serious assertions that warrant scrutiny and further investigation, given their potential implications for disclosure.

Please watch the full interview and consider its significance within the broader context of the disclosure conversation. Please note that the interview concludes with a paid promotional pitch, and Grusch does not provide any additional comments after the pitch.

Stellar CEO Reveals Where Real Opportunity Lies in Crypto Market: Details

In a recent tweet, Stellar Development Foundation (SDF) CEO and Executive Director Denelle Dixon defines what "real opportunity" is in blockchain as a new financial future beckons.

The SDF CEO was reacting to a recent Bloomberg report on Bank of New York Mellon Corp (BNY), Nasdaq, S&P Global and iCapital participation in a new $50 million investment round by Digital Asset Holdings. This comes as some of Wall Street’s biggest names embrace the technology that underpins cryptocurrencies to handle traditional assets.

Reacting to this development, Stellar Foundation CEO Denelle Dixon stated that every blockchain investment is a bet on a different financial future. Dixon added that seeing banks explore blockchain technology validates what has been known over the years.

Real opportunity defined

While Wall Street’s biggest names betting on blockchain might be one of the most significant adoption milestones in the digital asset market, Dixon defines what real opportunity is and what it is not.

According to the SDF executive director, real opportunity is not replicating old systems on new rails but rather building open networks that fundamentally expand global finance participation.

"But the real opportunity isn’t replicating old systems on new rails—it’s building open networks that fundamentally expand who gets to participate in global finance. That’s the opportunity," Dixon tweeted.

At the Meridian 2025 event, Stellar outlined its long-term privacy strategy, committing to investing in critical privacy infrastructure and building foundational cryptographic capabilities.

Stellar eyes privacy upgrade

A new protocol upgrade is on the horizon for the Stellar network: X-Ray, which lays the groundwork for developers to build privacy applications on Stellar using zero-knowledge (ZK) cryptography.

The protocol timeline testnet vote is anticipated for Jan. 7, 2026, while the mainnet vote is expected for Jan. 22, 2026.

XDC Network's acquisition of Contour Network

XDC Network's acquisition of Contour Network marks a silent shift to connect the digital trade infrastructure to real-time, tokenized settlement rails.

In a world where cross-border payments still take days and trap trillions in idle liquidity, integrating Contour’s trade workflows with XDC Network Blockchains' ISO 20022 financial messaging standard to bridge TradFi and Web3 in Trade Finance.

The Current State of Cross-Border Trade Settlements

Cross-border payments remain one of the most inefficient parts of global finance. For decades, companies have inter-dependency with banks and their correspondent banks across the world, forcing them to maintain trillions of dollars in pre-funded nostro and vostro balances — the capital that sits idle while transactions crawl across borders.

Traditional settlement is slow, often 1–5 days, and often with ~2-3% in FX and conversion fees. For every hour a corporation can’t access its own cash increases the cost of financing, tightens liquidity that could be used for other purposes, which in turn slows economic activity.

Before SWIFT, payments were fully manual. Intermediary banks maintained ledgers, and reconciliation across multiple institutions limited speed and volume.

SWIFT reshaped global payments by introducing a secure, standardized messaging infrastructure through ISO 20022 - which quickly became the language of money for 11,000+ institutions in 200 countries.

But SWIFT only fixed the messaging — not the movement. Actual value still moves through slow, capital-intensive correspondent chains.

Regulated and Compliant Stablecoin such as USDC (Circle) solves the part SWIFT never could: instant, on-chain settlement.

Stablecoin Settlement revamping Trade and Tokenization

Stablecoin such as USDC is a digital token pegged to the US Dollar, still the most widely used currency for trade, enabling the movement of funds instantly 24*7 globally - transparently, instantly, and without the need for any intermediaries and the need to lock in trillions of dollars of idle cash.

Tokenized settlement replaces multi-day reconciliation with on-chain finality, reducing:

  • Dependency on intermediaries
  • Operational friction
  • Trillions locked in idle liquidity

For corporates trapped in long working capital cycles, this is transformative.

Digital dollars like USDC make the process simple:

Fiat → Stablecoin → On-Chain Transfer → Fiat

This hybrid model is already widely used across remittances, payouts, and treasury flows.

But one critical piece of global commerce is still lagging:

👉 Trade finance.

The Missing link is still Trade Finance Infrastructure.

While payments innovation has raced ahead, trade finance infrastructure hasn’t kept up. Document flows, letters of credit, and supply-chain financing remain siloed, paper-heavy, and operationally outdated.

This is exactly where the next breakthrough will happen - and why the recent XDC Network acquisition of Contour is a silent revolution.

It transforms to a new era of trade-driven liquidity through an end-to-end digital trade from shipping docs to payment confirmation – one infrastructure that powers all.

The breakthrough won’t come from payments alone — it will come from connecting trade finance to real-time settlement rails.

The XDC + Contour Shift: A Silent Revolution

  • Contour already connects global banks and corporates through digital LCs and digitized trade workflows.
  • XDC Blockchain brings a settlement layer built for speed, tokenization, and institutional-grade interoperability and ISO 20022 messaging compatibility

Contour’s digital letter of credit workflows will be integrated with XDC’s blockchain network to streamline trade documentation and settlement.

Together, they form the first end-to-end digital trade finance network linking:

Documentation → Validation → Settlement all under a single infrastructure.

XDC Ventures (XVC.TECH) is launching a Stable-Coin Lab to work with financial institutions on regulated stablecoin pilots for trade to deepen institutional trade-finance integration through launch of pilots with banks and corporates for regulated stable-coin issuance and settlement.

The Bottom Line

Payments alone won’t transform Global Trade Finance — Trade finance + Tokenized Settlement will.

This is the shift happening underway XDC Network's acquisition of Contour is the quiet catalyst.
