S&P Global Ratings confirmed on October 1 that the issuer credit rating of the stablecoin protocol Sky Protocol is B-, with a stable outlook. S&P stated that Sky is advancing the Prime Agent ecosystem (formerly Stars or subDAO), which includes strategies such as over-the-counter lending with a scale of approximately $1 billion, accounting for about 10% of the total assets supporting USDS and DAI; these semi-independent entities use the Sky balance sheet for specialized investments within the risk parameters set by governance, while increasing management and monitoring complexity.The total supply of USDS and DAI increased from $7.7 billion in August 2025 to $9.5 billion. As of September 17, 2026, reserves are approximately $92 million, with a target of $150 million. Robust assets USDC and tokenized money market funds backed by government bonds total approximately $4.92 billion, accounting for about 50% of circulating USDS and DAI, up from 36% in August 2025. On-chain crypto lending has decreased to about 25% of the balance sheet, while over-the-counter crypto lending has increased to approximately $1 billion. Newly included assets include RLUSD, PYUSD, and USDG totaling approximately $392 million, as well as a tokenized fund investing in AAA-rated CLO shares of about $500 million.As of September 2026, the four major Prime Agents account for approximately 65% of the combined assets, with Spark accounting for 36%, Grove for 24%, Obex for 4%, and Osero for 1%.

According to Decrypt, the European Union's law enforcement agency reported that Spanish police arrested a 16-year-old Romanian suspect in Alicante, suspected of being an administrator and main operator of the ransomware group KillSec.Two other suspects in their twenties were arrested in the UK and Romania, respectively; another developer who just turned 18 in August this year has been identified but has not been arrested due to some crimes occurring during their minor years.This operation, codenamed Operation KillSwitch, was led by the Hamburg State Criminal Police and the city's prosecution office, focusing on approximately 1,000 suspected attacks worldwide, with about 500 confirmed as successful intrusions.Law enforcement searched eight locations in Spain, Greece, Romania, and the UK, seized five central servers, and redirected related domain names to seizure announcement pages, while also confiscating at least 110 TB of stolen data.KillSec has been active since around 2024, exploiting software vulnerabilities and poorly secured cloud storage entry points to infiltrate corporate systems, copying internal data and naming victim organizations on dark web leak sites, threatening to publicly release documents to demand cryptocurrency ransoms, and if the target refuses to pay, they release the data for free.The Swiss Federal Police noted that the group also employed double extortion tactics, first encrypting servers and then applying pressure. U.S. prosecutors' charges indicate that a Dutch national residing in the UK, Fouad Eltibrizi (nicknamed Archduke), was indicted by a federal grand jury in Puerto Rico on September 16, subsequently arrested, and awaiting extradition, facing up to 10 years in prison. The European Cybercrime Centre, under the European Union Agency for Law Enforcement Cooperation, is assisting in tracing cryptocurrency funds and conducting digital forensics.

According to Cointelegraph, the Bitcoin Policy Institute (BPI) released a research report questioning the process by which MSCI established its latest index rules. MSCI had previously listed companies such as Strategy and Metaplanet as potential "non-operating companies," which could lead to their removal from the index.MSCI first proposed excluding digital asset treasury companies from global indices in 2025, but after facing opposition, it shelved the plan in January and opted for a broader review of "non-operating companies." On August 3, MSCI put forward a broader proposal that could still result in the exclusion of Strategy and Metaplanet. In a report titled "The Invisible Committee of Wall Street," BPI pointed out that metadata shows the presentation MSCI consulted is stored in an internal folder specifically for digital asset treasury companies.According to the proposal, MSCI will first assess whether a company has a significant amount of operational assets before applying five additional financial tests. Its own simulations indicate that Strategy, Metaplanet, and uranium investment company Yellow Cake would be excluded. In 2025, JPMorgan analysts estimated that if Strategy were excluded, it could face an outflow of approximately $2.8 billion. BPI also questioned MSCI's reliance on "operational assets," stating that the term is not a standardized balance sheet category under U.S. GAAP or IFRS. MSCI concluded its opinion collection on September 30 and is expected to announce results on or before October 16, with related changes set to take effect during the index review in November 2026.

According to CoinDesk, the U.S. Securities and Exchange Commission (SEC) proposed a significant update to the transfer agent rules on September 1, the first since the 1970s. Chairman Paul Atkins explicitly stated that the rules should cover the application of blockchain technology in securities issuance and equity transfer.Joris Delanoue, co-founder of Fairmint, pointed out that if ownership data is scattered among token wrapping layers, SPVs, broker-dealer internal ledgers, and off-chain databases, it will replay the historical "paperwork crisis" of the late 1960s. He emphasized that the tokens themselves should serve as the official ledger required by Section 17A of the Securities Exchange Act, rather than as off-chain securities wrapping substitutes. The article calls for the industry to integrate ownership data around unified open standards and suggests that the SEC distinguish between native on-chain registration and third-party wrapping models in Form TA-2, allow the use of cryptographic credentials and other modern identifiers, and incorporate pre-trade restrictions on smart contracts into compliance enforcement mechanisms.

Cryptocurrency payment company MoonPay announced the establishment of MoonPay Korea and is collaborating with South Korea's digital bank KakaoBank, commercial bank Woori Bank, and KB Financial Group to expand stablecoin payments and digital asset services in South Korea. MoonPay Korea will be responsible for local service development and will serve as the company's base for expansion in Asia. MoonPay's Asia-Pacific head Bugeon Lee stated that the stablecoin backed by the Korean won is expected to expand the coverage of South Korean financial institutions and provide new cross-border transaction methods for businesses, as the company hopes to build relevant infrastructure in South Korea with banking partners.The collaboration with KakaoBank focuses on blockchain-based overseas remittances, cross-border payments, and multi-currency stablecoin services. The two parties plan to initially conduct a proof of concept aimed at international students, testing the complete process of initiating transfers from South Korea, transferring via stablecoin, and converting to US dollars for deposit into a US bank account. The collaboration also covers the issuance and distribution of won-pegged stablecoins, payment settlements, as well as trading, custody, and conversion of stablecoins denominated in won, US dollars, yen, and others, with access to MoonPay's global distribution and payment network supported by assets and regions.MoonPay will collaborate with Woori Bank to provide global distribution for future won-pegged stablecoins and validate the cross-border payment settlement model for local businesses based on stablecoins. The partnership with KB Financial Group will explore card payments, global remittances, wallet custody, and stablecoin usage for individuals, institutions, and foreigners in South Korea.

According to CoinDesk, Zcash developers are integrating part of the proposed scaling upgrade code, Tachyon, into the software already in use to prepare for a large number of privacy transactions in the future. This component is named Udon, originally developed as part of Project Tachyon.According to Sean Bowe, the head of Project Tachyon, Udon was released on Monday to Zakura Common, which is a cryptographic library shared by Zakura and other Zcash projects. Common is responsible for handling some of the heavy mathematical computations behind creating and verifying privacy transactions, with Zakura being jointly developed by Bowe's team and Dev Ojha's Valar Group.Zcash wallets need to prove the validity of a privacy payment without disclosing the payer, payee, or amount, and the computers running the network subsequently verify that proof. According to CoinDesk's report in August, previous improvements to Common have reduced the time to create a privacy transaction from over 3 seconds to under 200 milliseconds in some tests.If privacy payments become more common, these computers will need to handle more data. Udon brings some of the computational requirements for the proposed scaling upgrade of Tachyon into Common, allowing developers to continue building on the already accelerated code. Udon has been released as software, but the upgrade has not yet been activated on Zcash.Bowe and Ojha's long-term goal is to exceed 50,000 payments per second. At this rate, they estimate that current cryptography will allow each Zcash node to receive over 500 MB of data per second.
