The cryptocurrency industry organization BlockchainAssn has submitted an amicus brief in support of Custodia Bank's application to the U.S. Supreme Court, urging the Court to review whether regional Federal Reserve Banks have the authority to deny access to master accounts for qualified state-chartered banks. The organization warns that lower court support for the Federal Reserve's ruling grants the central bank broad powers to disqualify industries or companies it does not recognize from receiving banking services, effectively vetoing which state-chartered banks can operate.Meanwhile, the Kansas City Federal Reserve Bank has been granted an extension until September 11 to respond to Custodia's application.

Web3 security company CertiK released the report "Intel3D: PSAV and Brazil's New Security Standards." The article points out that as the deadline for authorization applications set by the Central Bank of Brazil (October 30 of this year) approaches, local virtual asset service providers (PSAV) are facing a round of concentrated compliance adjustments, and compliance and security certifications issued by independent third parties are transitioning from industry best practices to important requirements for market access.According to the report, CertiK is currently conducting independent external audits based on the Central Bank of Brazil's Normative Instruction No. 701. As one of the markets with the highest adoption of crypto assets globally, the impact of this regulatory transformation in Brazil may far exceed the local market. The report shows that Brazil currently ranks fifth in the world for actual crypto asset adoption rates. From June 2024 to June 2025, the on-chain asset value received by Brazil reached $318.8 billion, accounting for nearly one-third of on-chain activity in South America during the same period. Stablecoins have become an important infrastructure in the local digital asset market, accounting for about 80% of the trading volume in crypto asset transactions reported to the Federal Revenue of Brazil.

Circle's Senior Director of Strategy and Policy, Patrick Hansen, stated that after the comprehensive implementation of the EU's Markets in Crypto-Assets Regulation (MiCA), licenses have been issued for 35 electronic currency tokens from 21 issuers, and local issuers are making good progress. Patrick Hansen pointed out that the strict regulations of MiCA have made it impossible for most major stablecoin issuers, including Tether, to meet operational requirements. Currently, only USDG, USDC, and EURC comply with the framework requirements, while other stablecoins fall outside the regulatory scope of MiCA, leaving EU users unprotected or unable to access services.He believes that the upcoming review of MiCA should address this issue and provide a more pragmatic operational pathway for foreign issuers. The EU's Directorate-General for Financial Stability, Financial Services, and Capital Markets Union launched a public consultation on May 20 to assess whether the current framework is still applicable, with the consultation continuing until September 30.

World Chain will launch a complete block access list on the mainnet on August 17, enabling this feature through a runtime flag without coordinating a hard fork across the network. The network claims it will be the first production-level L2 network to stream EIP-7928 access list data within each flashblock.This feature transmits access list data every 200 milliseconds, allowing validators to verify transactions in parallel during the block construction process. World Chain states that the upgrade aims to achieve a maximum throughput of 1 gigagas per second without increasing the hardware requirements for validators. EIP-7928 is an Ethereum upgrade proposal that introduces block-level access lists to record accounts and storage slots accessed during block execution. Internal testing by World Chain shows that when throughput rises to 1 gigagas per second on standard cloud infrastructure, validation latency remains stable.

Gate Research Institute released a thematic report on Robinhood Chain. The report points out that Robinhood Chain aims for tokenized stocks, ETFs, and other RWAs as its long-term direction, but in the early stages of the mainnet launch, growth is primarily driven by Meme, Launchpad, and Uniswap trading, forming a structure where RWA serves as a long-term asset endpoint and Meme acts as a short-term liquidity engine. The high turnover of popular tokens such as CASHCAT and PONS reflects that the market is pricing around the Robinhood brand, on-chain retail trading culture, and launch platform traffic.The report also believes that Gate DEX's comprehensive access to Robinhood Chain supplements the ecosystem's external multi-chain entry points. In the early development stage of Robinhood Chain, AMMs like Uniswap mainly undertake price discovery and liquidity formation for on-chain assets, while Gate DEX complements the inflow paths for external funds and users through asset discovery, trading entry, and cross-chain capabilities. Gate Alpha supports the discovery and trading of ecosystem assets and multiple launch platforms, while Gate Wallet, Swap, professional trading, and market modules simultaneously cover this network; relying on Across and LayerZero, users can conduct cross-chain exchanges between BSC, Ethereum, Base, and Robinhood Chain. Overall, Gate DEX mainly undertakes asset distribution and fund routing functions within the ecosystem, helping Robinhood Chain connect with a broader multi-chain user base by lowering the operational threshold for users to discover assets, enter cross-chain, and participate in trading.

According to GMGN data, the market capitalization of the SOL Meme coin CATE briefly surged past $9.5 million, with an intraday increase of over 230 times, currently reported at $7.09 million. The market enthusiasm for CATE stems from a new rescue kitten video released by DOGE owner @kabosumama.Subsequently, community user @HimothyGoggins retweeted and speculated that the cat was named "Hiromi," but this claim has not been confirmed by Kabosu's owner. Afterward, @thedevrrrrrrr suggested "running CATE like DOGE," and the token was quickly created on Pump.fun, attracting community attention.It is important to note that there is currently no evidence that this cat is named Hiromi, nor has it been officially confirmed to be named CATE. The name CATE comes from the previous "Cate" cat meme, which has been repurposed by the community for the dissemination of this event. CATE is not an official token of Kabosu's owner, nor is it named after the actual name of the cat, but rather a community meme coin formed by combining real events with existing internet memes. According to market news, meme coin prices are highly volatile, so please be aware of market risks.

Enterprise users can obtain up to a 40% cost discount through this model, making it easier to flexibly balance performance and budget expenditures based on actual business loads. Developers can log in to the B.AI official platform starting today to experience the exceptional capabilities of Claude Opus 5 first-hand.

Anthropic upgrades Claude's voice mode. Paid users can now choose Opus, Sonnet, and Haiku, no longer limited to the faster but less capable Haiku.Users can switch models during conversations and can also switch to text at any time. Claude defaults to the model selected in the last text chat and calls the fastest version in that series. The voice mode can also access Gmail, Google Calendar, Google Docs, and Slack. Users can have Claude check emails, change schedules, or draft replies, and will request authorization before executing.The new version is now available for testing on mobile, desktop, and web. Free users can only use Haiku and one connection tool. Voice now supports multiple languages including English, Japanese, and Korean, but does not include Chinese at this time. This upgrade mainly enhances model reasoning and tool invocation capabilities. Anthropic has not changed the voice model, so the naturalness of speech and interruption experience may not show significant changes.
