U.S. SEC Chairman Paul S. Atkins stated at the 2026 Reagan National Economic Forum that the U.S. Securities and Exchange Commission is advancing a "New Era SEC" regulatory reform, focusing on modernizing digital asset regulation, promoting on-chain capital market development, and supporting the U.S. in becoming a "global crypto hub."Paul Atkins criticized the SEC's previous "regulatory hostility" towards the digital asset industry, alleging that much crypto innovation was forced to relocate overseas. He stated that with the support of the Trump administration, the SEC has launched "Project Crypto" and is collaborating with the Commodity Futures Trading Commission to promote on-chain market infrastructure and harmonize crypto regulation. The SEC has recently clarified which digital assets are securities and which are not, and is advancing an innovative exemption mechanism for "tokenized listed securities," while studying how on-chain trading systems can fit within existing regulatory frameworks.Additionally, Paul Atkins emphasized that the SEC will reduce "over-disclosure" and regulatory burdens, promote "Make IPOs Great Again" reforms, including lowering compliance costs for listed companies, increasing IPO flexibility, and formally proposing to repeal the climate disclosure rules introduced under the previous administration. The future of U.S. capital markets should be built on a "free market and innovation-driven" foundation, where the regulator's role is to provide clear rules and legal certainty, not to suppress technological development.
: Sui announced on the X platform that its mainnet has resumed normal operations, and transaction flow has stabilized. The official confirmed that both network outages yesterday and today were caused by an interaction issue between the Address Balances feature introduced in version 1.72 and the Gas billing logic. The fix deployed yesterday was a temporary measure aimed at quickly restoring network functionality, but it had a known issue with a "low probability of triggering an outage." Today, a variant of that issue was triggered on the mainnet, causing the network to pause again.Currently, validators have completed the deployment of a long-term fix. The official stated that the known issue has been thoroughly resolved, and network activity has fully recovered. The Sui team said a more detailed post-mortem report will be released subsequently.

According to Forbes, Western Union will launch its stablecoin USDPT on the Solana blockchain in May 2026. Issued by Anchorage Digital Bank, USDPT will be accompanied by a digital asset network designed to connect crypto wallets and exchanges. Analysts note that this move represents Western Union’s deliberate disruption of its core profit model: traditionally, the company relies heavily on foreign exchange spreads in cross-border remittances, but near-instant settlement via stablecoins will render such spreads transparent and unsustainable. At the same time, Western Union must still bear substantial fixed costs associated with its extensive offline agent network—a burden absent from crypto-native remittance firms from day one. The company’s Q1 financial report already reflects mounting pressure, with net income halved year-on-year to $65 million.
private equity giants Apollo Global Management and Blackstone Group are bringing in more investors for a debt financing deal worth approximately $36 billion to help Anthropic build its artificial intelligence infrastructure.According to insiders, this debt financing will be used to purchase Google's custom TPU (Tensor Processing Unit) chips, which will then be leased by Anthropic. Broadcom, which assisted Google in developing the chip, will provide guarantees for the majority of this deal. This move is expected to become one of the largest private credit transactions in history and potentially the biggest debt financing deal for chips to date. The plan aims to leverage Broadcom's credit standing to provide computing power support for Anthropic.
Odaily News, the U.S. Commodity Futures Trading Commission (CFTC) Market Participants Division today issued an interpretive opinion and a "No-Action Letter" in response to an application from Coinbase Financial Markets, allowing it to offer trading services for certain digital commodity derivatives through its affiliated offshore trading platform, Deribit. CFTC staff confirmed that, based on the framework approved for Kalshi's BTCPERP contract on May 29, 2026, relevant crypto perpetual contracts can be classified as "foreign futures" as defined under Regulation 30.1.Simultaneously, under the fulfillment of specific conditions, the CFTC's Market Participants Division stated it does not recommend enforcement action against Coinbase Financial Markets. This allows Coinbase to transfer customer-held digital commodities and stablecoins, used as margin, to its affiliated offshore broker-dealer to support trading positions in foreign futures and options, even if the relevant offshore broker-dealer has the right to rehypothecate these assets.Analysts believe this statement further clarifies the classification path for crypto perpetual contracts within the U.S. regulatory framework and provides institutional space for compliant entities to access derivatives trading through offshore liquidity markets.
the U.S. Commodity Futures Trading Commission (CFTC) announced today that it has issued an approval order to KalshiEX, LLC, a designated contract market (DCM), allowing it to list the perpetual contract BTCPERP, which references the spot price of Bitcoin, for trading as a futures product. The contract was submitted for review on May 29, 2026, pursuant to CFTC Regulation 40.3.The CFTC reviewed the BTCPERP contract under Section 5c(c)(4) of the Commodity Exchange Act (CEA) and relevant regulations, confirming that it complies with the CEA and CFTC rules, including core principles applicable to DCMs. The approval order requires Kalshi to strictly adhere to the CEA and all relevant CFTC regulations when listing and maintaining the contract.The CFTC also noted that the perpetual contract structure is not suitable for all asset classes and encouraged market participants to voluntarily submit applications for perpetual contract approval under the 40.3 rulemaking for uncovered assets to ensure compliance and robust market development.
Coinbase has announced it has become the first and currently the only Futures Commission Merchant (FCM) regulated by the U.S. Commodity Futures Trading Commission (CFTC), providing U.S. clients with access to the global crypto derivatives market, including crypto perpetual contracts and options. Previously, U.S. institutions could only trade crypto products derived from domestic futures exchanges, lacking access to global markets.Previously, U.S. clients were unable to participate in such global markets through compliant channels and had to establish offshore entities to access liquidity, resulting in increased counterparty risk and duplicated infrastructure costs. Through a single CFTC-regulated FCM, Coinbase Financial Markets is opening compliant access to global crypto options and perpetual contracts for U.S. institutional clients, including connectivity to platforms like Deribit, whose Bitcoin options open interest exceeds $31 billion, accounting for the vast majority of the global options market.Institutional clients can begin onboarding immediately. Deribit options are now available via Coinbase Financial Markets, with perpetual contracts and additional collateral types to be rolled out gradually. Broader access for retail clients is also in the pipeline.This move means that U.S. clients can finally participate in the world's largest and most liquid crypto derivatives market through a single, regulated channel, providing institutional investors with a more complete and compliant trading environment while reducing cross-border operations and complexity.
Binance has posted a teaser on X platform, announcing that it will reveal a new product on June 1.
According to CoinDesk, the U.S. Commodity Futures Trading Commission (CFTC) approved, for the first time on May 29 local time, a regulated exchange to list and trade Bitcoin perpetual futures contracts (“Perps”), marking the first such case in U.S. regulatory history. CFTC Chair Mike Selig characterized this move as a “significant milestone,” stating that perpetual contracts serve as foundational risk-management and price-discovery tools in global crypto-asset markets, and that the CFTC will provide an actionable regulatory framework for such contracts while restricting excessive leverage and systemic risk. Previously, perpetual contract trading had long migrated to non-U.S. jurisdictions due to the absence of regulatory oversight. The CFTC has not yet disclosed the names of the first batch of approved exchanges, and this policy has not yet been elevated to the level of formal regulation—meaning it remains subject to potential reversal in the future.
the U.S. Commodity Futures Trading Commission (CFTC) departments, including Market Oversight, Clearing and Risk, jointly issued staff guidance outlining regulatory expectations and compliance requirements for the growing 24/7 trading, clearing, and settlement model in the markets, encouraging market innovation while ensuring compliance.The guidance emphasizes that regulated trading platforms, swap execution facilities, derivatives clearing organizations, and futures commission merchants must comply with the Commodity Exchange Act (CEA) and relevant regulatory rules when expanding to 24/7 trading, and must proactively assess risk management and operational arrangements.The CFTC noted that different asset classes have varying suitability for 24/7 trading. Derivatives related to crypto assets, due to their digital infrastructure and global continuous trading characteristics, are more suitable for around-the-clock trading and clearing. In contrast, traditional commodity derivatives such as agricultural products, due to their regional and trading structure characteristics, may not be fully suited for 24/7 operations.CFTC staff stated that relevant institutions should ensure they meet the regulatory framework and risk control requirements while promoting continuous market evolution, in order to support "responsible market innovation."
: The Zcash Foundation has released version 4.5.0 of its node client, Zebra. This update includes multiple security fixes, addressing a critical consensus vulnerability and several high-severity Denial of Service (DoS) issues. All node operators are strongly urged to upgrade immediately.Key fixes in this release include a sigop counting error in P2SH script parsing (which could cause a consensus fork with zcashd), a logic flaw in NU5 block validation caching, a crash risk related to transparent address balance overflow, along with multiple crash and resource exhaustion vulnerabilities in RPC interfaces and mempool processing. The Foundation stated that some vulnerabilities could be exploited by malicious nodes, leading to node stalls, restart loops, or even permanent stoppage.Additionally, this version adds support for ZIP-213 (enabling shielded coinbase outputs to Sapling) and optimizes network performance and security boundaries. This includes limiting resource allocation during the pre-handshake phase, fixing risks related to multi-threaded queue abuse, and enhancing the misbehavior scoring mechanism.The Zcash Foundation stated that this update addresses over 80 security reports from the ZCG Vulnerability Disclosure Program (spanning April to May 2026), covering multiple layers including consensus security, memory management, RPC processing, and the P2P network attack surface. Officials emphasized that there is no alternative to this upgrade; upgrading is the only way to ensure nodes do not experience a chain split and remain secure.
