Arm approved a one-time engineering fee at the end of August for the development of the next-generation edge AI SoC chip and officially started the project with Samsung Electronics.The project adopts a collaborative model where Arm provides core technology, and Samsung Electronics integrates and implements it, aiming to jointly develop customized chips for end customers.

The International Monetary Fund (IMF) announced that it has reached a staff-level agreement with the authorities of El Salvador on the second and third combined reviews under the Extended Fund Facility arrangement. If approved by the IMF Executive Board, El Salvador will receive approximately $140 million (101.96 million SDR).Regarding Bitcoin-related arrangements, the IMF confirmed several key facts: the Chivo electronic wallet has essentially withdrawn from public participation, with majority ownership and operational control transferred to private operators; the increase in Bitcoin holdings since the first review has been verified as coming from private donations, with no public resources utilized; El Salvador has committed that there will be no further increases in Bitcoin holdings beyond the recorded private donations. The two parties also reached an understanding on modernizing the legal, regulatory, and supervisory framework for digital assets, as well as strengthening governance and risk management arrangements for public sector cryptocurrency holdings.

According to lawyer Ariel Givner, cryptocurrency hardware wallet manufacturer Ledger is facing a class-action lawsuit in the United States due to a security incident in 2023. The plaintiffs claim that the incident led to the leakage of personal identification information such as customer names, email addresses, and phone numbers, and that Ledger failed to timely and adequately disclose the relevant situation.The lawsuit also points out that hackers subsequently used this contact information to impersonate Ledger, tricking users into approving fraudulent transactions and stealing cryptocurrency assets.

Venture capitalist Tomasz Tunguz posted on X that the cutting-edge AI market is splitting into closed camps, with labs choosing partners, cutting off competitors, and rationing access to the strongest models. Salesforce selected Anthropic as its dedicated AI partner, making Claude the default model for the world's largest CRM and Slack.OpenAI cut off its API access on November 12 after SpaceX acquired Cursor. Z.ai placed its flagship model under a security review after cumulative revenue exceeded $10 billion. Anthropic rationed Mythos 5 through Project Glasswing and restricted Fable to inference only in the United States. OpenAI first launched the GPT-5.6 variant to trusted partners.Nvidia is investing in an open ecosystem, including $13 billion for Hugging Face, $7 billion for Poolside, and a $26 billion commitment to Nemotron. Tunguz stated that access, rather than price, has become the new scarcity at the forefront.

Ayo Akinyele, Senior Director of Engineering at Ripple, stated that the company is developing a four-phase quantum-resistant migration plan for the XRP Ledger, aiming to complete the transition before quantum computers become a real threat. The plan includes assessing the network's exposure, testing quantum-resistant cryptographic solutions, running existing security systems in parallel with quantum-resistant alternatives, and preparing emergency response pathways for scenarios where quantum computing advances exceed expectations.Akinyele emphasized that migration is not just about replacing a cryptographic algorithm, but requires more flexible infrastructure, stronger key management, and clearer upgrade paths. The XRP Ledger has supported changing the keys that control accounts without altering the accounts themselves, a feature that is expected to reduce the difficulty of future migrations, but independent validators on the network still need to coordinate any broader rule changes.Meanwhile, Anthropic's model last month reduced the workload required to break leading post-quantum signature candidates by 67 million times, and Bitcoin and Ethereum developers also released their respective migration plans this week. Akinyele pointed out that AI and quantum computing are different technologies, but they are driving financial infrastructure to evolve in the same direction, as AI agents begin to trade and pay autonomously, raising new requirements for payment infrastructure that is always online and natively internet-based.

The security team of the open-source wallet provider OneKey successfully replicated the exploitation of a vulnerability in the old version of the Ledger Ethereum application in a laboratory environment. OneKey's founder and CEO Wang Yishi stated that they executed a "transaction replacement attack" on Ledger Ethereum application version 1.22.1 by exploiting a previously patched vulnerability, allowing attackers to overwrite pending transactions while users review legitimate transactions.Ledger responded that exploiting this vulnerability requires controlling the communication between the device and the host, such as through malware, compromised wallet software, or malicious web pages. Ledger has added application layer protections in the Ethereum application version 1.22.2 released on August 13 and fixed the underlying issue in Secure SDK 26.6.1 on August 21. Ledger emphasized that no users were hacked as a result; this was merely a replication of the vulnerability in a laboratory environment.This security test occurred after the Coldcard vulnerability incident. Previously, the Coldcard wallet had a firmware vulnerability that posed security risks to some mnemonic phrase generation, but Ledger stated that its devices were not affected by this vulnerability because recovery phrases are generated by a certified random source built into the device's secure chip. The vulnerability replicated by OneKey is unrelated to mnemonic phrase generation but affects the way transactions are processed during the signing process.

Yesterday, Ledger disclosed details of the LSB 023 security vulnerability on its official website. Some applications built on the Ledger Secure SDK may still receive new APDU commands during the user screen confirmation, leading to inconsistencies between the parameters displayed on the screen and the final signature parameters.In cases where the attacker controls the APDU communication between the device and the host, after the user confirms the operation shown on the screen, the device may generate a signature with different parameters. Ledger stated that it has fixed the issue through application-level checks and the SDK layer, and released Ledger Secure SDK v26.6.1 on August 21. The relevant applications have been rebuilt and released. Users need to update the applications through Ledger Live; merely updating the device firmware is insufficient to complete the fix. However, Ledger claims there is currently no evidence that the vulnerability has been exploited.

Ledger's Chief Technology Officer Charles Guillemet stated that there has recently been "FUD" targeting Ledger in the market, as a smart contract security company claimed to have discovered vulnerabilities in the Ledger Ethereum application. Guillemet mentioned that there indeed were vulnerabilities related to certain Clear Signing processes in the Ledger Ethereum application, but these vulnerabilities were discovered by Ledger's security research team Donjon using AI-driven vulnerability research tools, and the fixes were completed and deployed two weeks ago. Users can obtain protection by timely updating their Ledger device firmware and applications.The relevant security company contacted Ledger's bug bounty program only after the fixes were completed, did not follow responsible disclosure processes, and did not communicate with the bug bounty team, yet implied in subsequent content that the issue had not been resolved. This approach is not true security research but rather a way to create panic for attention. AI is changing the cybersecurity landscape, and both attackers and defenders can enhance efficiency with AI, but AI-driven security research can only truly enhance the security of the entire ecosystem when basic security principles such as responsible disclosure and pre-release verification are followed.Guillemet finally reminded Ledger users to keep their device firmware, Ledger applications, and related software up to date to automatically receive the latest security fixes and research results. Users should not be influenced by the related "FUD" and should timely update their software and maintain safe habits.

Data shows that the total issuance of RLUSD is currently around $2 billion, with approximately $963 million deployed on the XRP Ledger and about $1.1 billion issued on the Ethereum network.Ripple previously stated that RLUSD will combine with its global payment network to provide more efficient on-chain liquidity solutions for businesses and financial institutions.

According to Cointelegraph, digital asset infrastructure provider Taurus has integrated its tokenization and custody platform with Swift's blockchain-based ledger. Taurus stated in the announcement that its clients can make payments on this ledger using bank-issued tokenized deposits through the existing digital asset infrastructure.The first batch of client integrations is expected to go live in a few days, with the first distributed ledger transactions completed through the Taurus platform anticipated to occur within weeks. Swift announced in July this year that the ledger is available for preliminary use, with 17 banks from six continents preparing to pilot real-time transactions using tokenized deposits.Previously, Standard Chartered Bank and HSBC completed the first real-time cross-border transaction through this ledger, connecting their respective independent tokenized deposit systems. Swift's ledger acts as a coordinating layer, supporting 24/7 cross-border payments for tokenized deposits on participating banks' balance sheets and coordinating inter-institutional transfers through existing mechanisms (including real-time gross settlement systems) before final settlement.

Cryptocurrency investment firm RockawayX announced the acquisition of the crypto hedge fund Relayer Capital to incorporate long-short strategies into its existing platform and expand its business footprint in the United States. RockawayX manages approximately $2 billion in assets, and Relayer will be renamed RockawayX Liquid Opportunities Fund, focusing on uncovering "undervalued liquidity tokens and crypto-related stocks." After the acquisition is completed, Relayer founder Austin Barack will serve as the chief investment officer of the fund, with Forbes citing informed sources that the company plans to raise $150 million for the fund.According to the announcement, Relayer's liquidity strategy has achieved approximately 70% net returns this year, outperforming a weighted basket of Bitcoin, Ethereum, and Solana by 86% as of August 21. The strategy expresses fundamental views on crypto tokens through long and short positions and pairs trading, while reducing overall market exposure at appropriate times. RockawayX CEO Viktor Fischer stated that now is the "right time" to implement this strategy, as there are crypto companies with real revenue and strong fundamentals emerging in the market, but inefficiencies and mispricing still exist, providing good opportunities for active investors.This transaction occurs amid a recent rebound in the crypto market, with Bitcoin recording its largest weekly dollar gain in history last week, dropping 1.68% to $79,064 in the past 24 hours after briefly reaching a high of around $81,000.
