OpenAI announced GPT-6 Astra, its most capable model for business work, featuring advanced reasoning, computer use, and stronger writing and design judgment. The rollout begins today with a limited set of organizations and will expand to all ChatGPT tiers, the OpenAI API, Microsoft Azure, and AWS Bedrock in the coming days.

This release signals a shift in enterprise AI from conversational chatbots toward models that autonomously operate computer interfaces and produce polished work output. It could reshape how organizations deploy AI for coding, writing, and repetitive interface tasks, intensifying competition among AI labs and their cloud partners.

The model is identified as gpt-6-astra with no shorter alias in OpenAI or EvoLink. GPT-6 Astra's computer-use capability lets it operate GUIs through code-driven actions or structured mouse and keyboard inputs; usage counts against existing subscription allowances, with extra credits available for purchase. An enterprise gated access program called Daybreak is also part of the rollout.

The U.S. government is backing a $300 million quantum computing hardware initiative, pushing Bitcoin and Ethereum to accelerate their quantum-resistant cryptography roadmaps. The move heightens urgency around the possibility that sufficiently powerful quantum machines could break the keys securing these networks.

Bitcoin and Ethereum rely on cryptographic assumptions that a large-scale quantum computer running Shor's algorithm could undermine, making this a systemic security issue for the entire crypto ecosystem. Government-funded hardware progress could shorten the timeline to that scenario, increasing pressure on networks to migrate before it arrives.

Current quantum computers remain far from the scale needed to break RSA, elliptic curve, or discrete logarithm cryptography, but migration to post-quantum algorithms takes years because of coordination and legacy systems. NIST released its first finalized post-quantum cryptography standards in 2024, and the industry is already debating how Bitcoin and Ethereum could adopt new signature schemes.

Anthropic released an interactive report titled 'Economic Scenarios for Transformative AI' (Working Paper No. 2026-02), with an accompanying web explorer that lets users examine possible economic outcomes as AI capabilities advance.

The report provides a structured framework for policymakers, researchers, and business leaders to reason about potential labor-market disruption, productivity growth, and societal adaptation. It adds a high-profile, forward-looking analysis to ongoing debates about how advanced AI could reshape the economy.

Based on the corresponding technical report by Korinek et al., the explorer is labeled version 1.0 and dated September 2026. It presents multiple scenarios rather than a single forecast, and is associated with the Anthropic Economic Index and the Anthropic Institute.

Trezor disclosed that its third-party email provider was breached, allowing attackers to send phishing emails from its legitimate domain. The fake alert claims a critical STM32 entropy vulnerability affects some devices and urges users to click a link; Trezor has taken down the malicious domain and is investigating.

Because Trezor is a leading hardware wallet maker, a compromised official email channel creates a credible phishing vector that could trick users into exposing recovery phrases or sending funds. The incident, which follows an earlier vendor breach and a recent Coldcard RNG exploit, underscores rising supply-chain and social-engineering risks in the crypto self-custody ecosystem.

The phishing email claims engineers found a 'critical hardware-level vulnerability' in STM32 microcontrollers and falsely estimates one in four devices could have weak recovery-phrase randomness. Trezor confirms that no wallets or private keys were exposed, while Casa's Nick Neuman and Jameson Lopp report that BitBox users received similar emails, suggesting the compromise may extend beyond a single provider.

Pump.fun opened token launches to quote assets beyond SOL and USDC on Wednesday, adding 93 pairs that include tokenized Nvidia, Tesla, and the S&P 500. The platform also directed half of the revenue from these new pairs into the PUMP buyback-and-burn contract.

This marks a prominent memecoin launchpad integrating tokenized traditional equities as quote assets, bridging TradFi and the memecoin economy. It could attract equity-focused traders to Solana DeFi while strengthening PUMP tokenomics through the buyback-and-burn revenue stream.

The new pairs coexist with Pump.fun's existing SOL- and USDC-quoted markets, and 50% of their revenue is routed to the PUMP buyback-and-burn contract. This builds on the platform's earlier burn of roughly $370 million of PUMP, about 36% of circulating supply, with cumulative buybacks and burns now reported at around $448 million across 164.13 billion tokens, representing roughly 16.4% of total supply.

Consensys Software Inc. announced on Wednesday that it will split into two independent companies by the end of 2026: MetaMask, the consumer self-custody and finance business, and a new institutional-focused Consensys that will house Ethereum protocols and infrastructure such as Linea, Besu, and Teku.

This restructures one of the most influential Ethereum software companies, separating the widely used MetaMask wallet from institutional blockchain infrastructure. The companies will now pursue different priorities, shaping the future of consumer self-custody and enterprise tokenization, with potential consequences for developers, financial institutions, and millions of wallets globally.

MetaMask reports over 100 million downloads across roughly 190 countries and has facilitated trillions of dollars in transaction volume. The new Consensys, led by CEO Mike Kriak and President David Cunningham, will focus on Ethereum infrastructure and institutional services such as tokenization, stablecoins, and onchain finance, while MetaMask, with Joe Lubin as chairman and CEO, expands beyond crypto into payments, savings, investing, and tokenized traditional assets.

U.S. Bank, the fifth-largest U.S. commercial bank, has successfully executed a live cross-border payment using its proprietary, U.S. dollar-backed stablecoin USBDC on the Stellar blockchain. The pilot moved funds between the bank's North American and European entities and tested minting, redemption, freezing, and clawback functions.

This marks one of the first instances of a major U.S. bank using its own stablecoin on a public blockchain for a real cross-border payment, signaling deeper institutional adoption of digital assets. It also highlights how banks are integrating compliance controls such as freeze and clawback into public-chain stablecoins, a design that diverges from censorship-resistant ideals but may satisfy regulators.

The transaction was part of U.S. Bank's internally developed Digital Asset Platform, which connects tokenized assets with its traditional banking infrastructure and integrates with risk, compliance, and operations systems. The bank had been testing stablecoin issuance on Stellar since at least November 2025, working with PwC and the Stellar Development Foundation; the latest announcement frames this as a launch of USBDC, though it remains a pilot rather than a large-scale rollout.

Tether and Fasanara Capital have launched StableFund, an evergreen private credit fund anchored by $400 million in co-investment from both sponsors and targeting up to $3 billion from institutional investors. The fund will use Tether's USDT as settlement infrastructure for short-duration, asset-backed lending through fintech platforms in more than 60 countries.

This marks the largest stablecoin issuer's formal entry into private credit, diversifying Tether's capital deployment beyond its stablecoin reserves and linking crypto settlement infrastructure to real-economy lending. It signals growing institutional adoption of stablecoin rails and could strengthen the connection between digital asset liquidity and traditional credit markets.

Fasanara, a London-based asset manager with over $6 billion under management, will manage the fund's investments, while Tether will source USDT-linked financing opportunities and provide on- and off-chain fund movement infrastructure. The fund will focus on small and medium-sized business and consumer lending, including trade receivables and supply chain finance.

PayPal has launched a platform that lets businesses issue and manage their own custom tokens on its stablecoin infrastructure. This expansion moves PayPal beyond processing payments into enterprise tokenization services.

This marks another step in institutional adoption of blockchain payments, giving mainstream companies a regulated route to create branded tokens. If adopted, it could significantly broaden stablecoin use cases beyond trading and remittances, while strengthening PayPal's position in the emerging tokenization economy.

The platform targets enterprises rather than individual consumers, enabling them to create and manage tokens on PayPal's existing stablecoin rails. Businesses can leverage PayPal's regulatory compliance framework and distribution network when issuing their own tokens.

BitMart passed its self-imposed Sept. 9 deadline without publishing the restructuring and business resumption roadmap it had promised; on Wednesday it instead appointed Alvarez & Marsal as financial adviser to evaluate its assets, financial position, and possible paths forward. The exchange also said it will launch a dedicated user-feedback web portal within five working days.

This is a material development for users with funds on BitMart, because a missed deadline combined with a restructuring adviser appointment signals deeper financial distress than prior statements suggested. It also affects confidence in centralized exchanges, as asset figures and a withdrawal timetable still have not been provided.

Alvarez & Marsal will work with BitMart's legal advisers to evaluate the exchange's assets, financial position, stakeholder issues, and possible paths forward, including proposals from unidentified third parties. Echo Base, which organized an ad hoc committee of BitMart claimholders, called the appointment 'the most encouraging step BitMart has taken since July,' while noting the absence of a reserve position, asset inventory, recovery estimate, or withdrawal timetable.

Tether froze more than $45 million in USDT across at least 22 wallets linked to Xinbi Guarantee, a marketplace serving Southeast Asian scam operations. Blockchain analytics firm Bitrace reported the action on Sept. 9, and Xinbi responded by telling users it would accept deposits only in USDD, a stablecoin built without address-level blacklisting capability.

This is a notable escalation in stablecoin-based law enforcement because a sanctioned entity is responding by migrating to infrastructure that is deliberately 'unfreezable,' potentially complicating sanctions enforcement and anti-money-laundering efforts. It also sharpens the policy debate over centralized versus decentralized stablecoin design and how regulators should treat tokens with no blacklist mechanism.

According to Bitrace, the freezes hit deposit, intermediary, and withdrawal addresses, including hot wallets for Xinbi's Xpay service and third-party OTC operators with financial ties to the marketplace. Replacement USDT wallets were frozen again within roughly 12 hours, and USDD — which has about $1.5 billion in circulation on Tron and Ethereum — documents itself as incapable of being frozen.
