The letter uses Ledger's official branding elements and mentions German financial regulators, while also including a QR code that directs users to a so-called mandatory registration process.The user believes that addresses exposed in a previous data breach are being used for targeted attacks on Ledger users. In the same week, Ledger coordinated with MediaMarktSaturn to suspend the sale of its hardware wallets in a European retail network covering 11 countries and over 1,000 stores.Earlier reports indicated that malicious spy implants were found inside Ledger devices purchased from European retailers.

Ledger has not confirmed any breaches of devices in Europe. Ledger users are currently facing physical supply chain tampering and targeted phishing attacks initiated using home addresses. Do not scan suspicious QR codes or enter recovery phrases.

The institutional settlement network Lynq, aimed at the digital asset market, and the stablecoin clearinghouse The Better Money Company (TBMC) announced the completion of a real-time proof of concept, demonstrating that institutional settlements can be completed in minutes. This proof of concept is part of the first phase of collaboration between the two parties, utilizing a pre-funded process to complete stablecoin settlements on Lynq.In the proof of concept, TBMC converted assets deposited by clients on Lynq into RLUSD, with settlements completed in minutes. The validation used real production accounts and real institutional counterparties, bypassing traditional banking windows during the settlement process. Interest continued to accrue on the assets during the settlement holding period, calculated using Tassat's Yield in Transit feature, determining accrued interest based on the duration of asset holdings.TBMC founder and CEO Sam Broner stated: "For stablecoins to become meaningful institutional infrastructure, they need to enter real settlement processes; this validation shows that stablecoin fragmentation can be handled through on-chain collateral transfer without relying on credit and traditional banking settlements for connection." Lynq CEO Jerald David remarked: "Institutions are not lacking in capital; what they lack is the ability to move funds to the right place in the right form when needed; this validation was intentionally kept small in scale, but it shows that digital dollars can settle between institutions in minutes, without substituting speed with credit convenience." Lynq stated that the platform's native stablecoin support is currently targeted for the end of 2026.
