Aztec Network has been hit by another $2 million hack, its second this week.

Following Sunday’s $2.2 million loss from Aztec Connect, Aztec’s Private Rollup Bridge has now been drained of a similar amount.

The firm stressed, in both cases, that the affected contracts are “immutable” and were “deprecated” in 2022 and 2023.

Today’s incident brings the tally of bridge-related exploits this year to 14, with over $340 million lost in total.

Security researcher Vishal Singh was first to flag the loss, which targeted the escapeHatch function of Aztec’s Private Rollup Bridge. The escapeHatch is an emergency measure which allows users to withdraw assets held on the rollup directly from Ethereum.

Yu Xian, founder of blockchain security firm SlowMist lists three suspicious transactions draining the Private Rollup Bridge. In all, around $2.15 million was drained as 1,158 ether, 150,000 DAI and 0.5 renBTC. 

He explains that, during the brief windows the hatch was “open,” anyone could trick the escapeHatch function into releasing the RollupProcessor-held funds by setting specific proofId and publicOutput parameters.

Double trouble

According to analysis from BlockSec, both Sunday’s and Thursday’s incidents, while not identical, were caused by “public input binding issues.”

The attack targeted Aztec’s RollupProcessorV3 contract, draining approximately $2.15 million of assorted crypto tokens.

DeFi protocols have faced a worrying tidal wave of attacks in recent months.

The hit rate appears to have dropped off somewhat in recent weeks, but the community braced itself for Anthropic’s Mythos release last week.

In the end, it turned out the model’s cybersecurity capabilities had been heavily “nerfed.”

Malta’s financial regulator is exploring how decentralized finance (DeFi) could fit within the European Union’s Markets in Crypto-Assets (MiCA) framework, focusing on governance, accountability and the meaning of “full decentralization.”

The Malta Financial Services Authority (MFSA) said that while MiCA excludes cryptocurrency services provided in a “fully decentralised manner without any intermediary,” many DeFi projects retain centralized features such as administrator keys, governance concentration, protocol upgrade rights and control over user-facing interfaces, in a discussion paper published Wednesday.

The regulator is seeking feedback on whether decentralization should be assessed as a spectrum rather than a binary concept and whether a standardized framework should be developed to determine when a protocol falls outside MiCA’s scope.

DeFi is something of a grey area under the EU’s framework for regulating crypto, as it excludes services provided in a fully decentralised manner, but lacks a clear description of when a protocol or platform meets that threshold.

MSFA’s paper also asks whether regulated crypto firms should be required to conduct smart-contract audits, governance reviews and risk assessments before integrating DeFi protocols into their services.

The upgrade marks a shift away from the protocol’s previous linear vesting model, in which tokens were auto-released to market regardless of demand, and it concluded earlier this year, in January 2026.

“Aster’s tokenomics upgrade puts the platform’s own activity to work,” the protocol noted, highlighting that the new rewards are settled on-chain with “no discretionary reserve.”

The token’s bullish price action, however, was short-lived as the Federal Reserve’s hawkish turn sent the dollar higher and weighed on risk assets, including cryptocurrencies.

As of writing, ASTER traded near 68 cents, down 5% on the day.

Key Takeaways

• Shares of Tesco declined more than 2% following Q1 UK like-for-like sales growth of only 1.8%, below market expectations
• Total group like-for-like sales reached £16.83 billion, with UK food sales advancing 2.6% and fresh food climbing 3.6%
• The Booker wholesale division struggled with like-for-like sales declining 3.2%, worse than the anticipated 2.4% drop
• Company reaffirmed full-year outlook: adjusted operating profit between £3–£3.3 billion and free cash flow of £1.5–£2 billion
• Chief Executive Ken Murphy attributed the weakness to challenging weather-related comparisons versus the prior year period

Shares of Tesco tumbled over 2% during Thursday’s trading session, hovering near 445p, following the release of first-quarter results that showed sales expansion trailing market forecasts for Britain’s leading grocery retailer.

Tesco PLC, TSCO.L

For the 13-week period concluding May 30, UK like-for-like sales advanced 1.8%. This figure fell at the lower boundary of consensus estimates and trailed Visible Alpha projections by approximately 50 basis points, representing a notable deceleration from the previous year’s growth trajectory.

Chief Executive Ken Murphy moved swiftly to downplay concerns. During a media briefing, he emphasized that weather patterns played a significant role in the outcome, noting that the comparison period from last year benefited from “outstanding” climatic conditions that unusually elevated performance.

“I wouldn’t be reading too much into it,” Murphy stated.

Overall group like-for-like sales similarly increased 1.8%, totaling £16.83 billion. Within the UK market, food sales posted a 2.6% gain, while fresh food categories delivered a stronger 3.6% uptick.

Analysts at Bernstein echoed Murphy’s assessment, characterizing the deceleration as likely seasonal and transitory. The firm identified moderating food price inflation, more difficult year-over-year comparisons, and weaker non-food category demand as primary drivers — rather than any fundamental deterioration in Tesco’s market standing.

Wholesale Division Struggles

The Booker wholesale operation emerged as an additional area of concern. Like-for-like sales in this segment contracted 3.2%, falling short of analyst projections for a 2.4% decrease.

Core retail sales within Booker declined 1.5%, partially attributable to the loss of a significant national customer account. The catering segment experienced a 3.3% downturn, which management linked to adverse weather conditions and Easter calendar timing.

Notwithstanding the top-line shortfall, Tesco maintained its full-year financial guidance. The company continues to project adjusted operating profit in the £3 billion to £3.3 billion range, alongside free cash flow between £1.5 billion and £2 billion for fiscal 2026/27.

Positive Developments Emerge

Beyond UK borders, Tesco’s Republic of Ireland operations delivered like-for-like growth of 3.3%, surpassing analyst expectations. Central European markets contributed 0.8% growth. Digital sales throughout international markets surged 17.4%.

Customer sentiment indicators also showed improvement. Tesco’s UK net promoter score advanced six points on a year-over-year basis. The retailer expanded its Aldi Price Match program into convenience store locations as part of its value-focused competitive strategy.

Management noted that Middle East geopolitical tensions have not materially impacted operations to date, though acknowledged the situation could potentially contribute to inflationary headwinds in subsequent quarters.

Regarding capital allocation, Tesco has executed £341 million in share repurchases since initiating its £750 million buyback program in April.

Anthropic’s AI models have lost another major banking user group in Hong Kong after JPMorgan restricted employee access to Claude under the company’s licensing terms.

The Financial Times reported that JPMorgan Chase employees in Hong Kong can no longer select Anthropic’s Claude models from the bank’s internal list of approved large language models. 

Three people familiar with the matter told the publication that the restriction stems from language in Anthropic’s licensing agreement. One person familiar with the decision said JPMorgan based the move on terms governing where the models can be used.

The development follows a similar decision by Goldman Sachs earlier this year. The Financial Times previously reported that Goldman blocked bankers in Hong Kong from using Anthropic models after determining that Anthropic’s terms of service exclude usage across Greater China, including Hong Kong.

Anthropic has not issued an official statement, but the company has previously told The Financial Times that Claude had never been officially supported in Hong Kong. JPMorgan declined to comment.

Hong Kong access faces new constraints

Western AI companies have generally restricted direct access to their most advanced models in mainland China. OpenAI’s ChatGPT and Anthropic’s Claude are unavailable there because of a combination of company policies and China’s internet controls.

Hong Kong has historically operated with fewer internet restrictions than mainland China. International firms have often obtained access to frontier AI models through global enterprise agreements and infrastructure hosted outside China.

The Financial Times reported that access limitations at major financial institutions have renewed concerns about Hong Kong’s ability to remain competitive as AI tools become more deeply integrated into software development, research, and financial services workflows.

Anthropic’s approach to geographic restrictions comes as U.S. AI companies face increasing scrutiny over how advanced models are used outside the United States. Industry observers and policymakers have expressed concerns that foreign users could employ frontier systems to accelerate domestic AI development through a process commonly known as model distillation.

Anthropic navigates multiple challenges

The banking restrictions arrive less than a week after Anthropic suspended access to its newly released Fable 5 and Mythos 5 models.

Anthropic announced on June 13 that it had disabled both systems after receiving a U.S. government export-control directive. The company said authorities instructed it to block access to the models for all foreign nationals, including foreign-national employees working within the United States.

Anthropic stated at the time that officials were concerned about a potential jailbreak technique that could allow the models to identify or repair software vulnerabilities. The company disputed the significance of the reported issue and said it believed the government action may have resulted from a misunderstanding.

Only two days later, Anthropic became the target of a proposed class-action lawsuit filed in the U.S. District Court for the Northern District of California. The complaint alleges that subscribers to the company’s $100-per-month Max 5x and $200-per-month Max 20x Claude plans received substantially less usage than marketing materials led customers to expect.

Plaintiff Karl Kahn seeks class-action status on behalf of customers who paid for Anthropic’s premium Claude subscriptions since April 2024. The filing argues that usage limits imposed on subscribers did not match the multipliers promoted for the plans.

Those disputes emerged shortly after Anthropic publicly called for stronger regulation of frontier AI systems. In its June 11 “Policy on the AI Exponential” proposal, the company urged governments to establish testing requirements, independent evaluations, cybersecurity standards, and enforcement mechanisms for the most advanced AI models.

Anthropic argued in that proposal that frontier systems can introduce biological, cybersecurity, and operational risks that require closer oversight as AI capabilities continue to advance.

Tether is winding down Alloy by Tether and its gold-backed, overcollateralized aUSDT stablecoin after a short run of about two years. In a statement posted Wednesday, the stablecoin issuer said the move follows an internal review of user activity, market demand, and the company’s “broader priorities,” adding that it wants to concentrate resources where it sees stronger demand and more enduring opportunities.

The shutdown is designed to be gradual. Tether will immediately stop new Alloy positions by preventing fresh aUSDT minting, and it is giving existing users a window to unwind their exposure by returning aUSDT and reclaiming the underlying XAUT by a cutoff date of Sept. 17.

Key takeaways

• Alloy by Tether is being phased out after Tether says demand and strategic fit are weaker than for other products.
• Tether is blocking new aUSDT minting immediately and sets Sept. 17 as the deadline for users to unwind their positions.
• aUSDT was built as an overcollateralized derivative of XAUT, using Ethereum smart contracts.
• XAUT remains active and is described by Tether as substantially larger in market capitalization than Alloy.
• 2025 also saw Tether discontinue CNHT (yuan) and EURT (euro) stablecoins, while it has continued to push tokenized real-world assets such as XAUT.

Why Alloy is shutting down now

Alloy by Tether was positioned as a bridge between gold exposure and dollar-like liquidity. According to Tether, it allows users to deposit XAUT—Tether’s gold-backed token—as collateral in order to mint or borrow against aUSDT. The design aims to keep the value of XAUT locked higher than the value of aUSDT issued, reflecting the overcollateralization model typical of collateralized synthetic assets.

In its announcement of “strategic changes,” Tether said it would focus on “stronger user demand, deeper liquidity and broader long-term market opportunity,” while continuing work across its broader ecosystem. The company explicitly pointed to XAUT—along with other core products—as areas it expects to be more central to its roadmap.

For users, the practical implication is that one of the most straightforward ways to convert gold token exposure into aUSDT liquidity will no longer be available. Traders and DeFi participants who used Alloy to avoid selling XAUT outright will now have to exit through Tether’s wind-down process rather than rolling positions forward.

How the wind-down works for aUSDT holders

Tether said the process will unfold in phases. The first phase begins immediately: users will not be able to open new positions and will be unable to mint additional aUSDT. Existing users will then have time to redeem their aUSDT and retrieve their XAUT.

Tether’s timeline gives users three months to return their aUSDT and reclaim their XAUT before the cut-off on Sept. 17. After that point, Alloy’s function as a collateral-to-aUSDT minting and borrowing mechanism will effectively be closed.

The key uncertainty for remaining participants is how smoothly the redemption process will be operationally handled at the cutoff. While Tether’s statement outlines the deadline and the general redemption mechanism, it does not provide additional details in the supplied text about any operational steps beyond users returning aUSDT to reclaim XAUT.

XAUT stays in focus as tokenized gold appears to drive demand

Even as Alloy is being wound down, Tether says its underlying gold token, XAUT, continues to attract users. In Tether’s framing, XAUT is “popular,” with market capitalization of about $3 billion and physical backing of 22,169 kilograms of gold, according to the company.

By contrast, Tether said Alloy by Tether currently has a market capitalization of $1.2 million and is backed by 14.73 kilograms of gold worth around $2.2 million, based on Tether information from Alloy’s site. That disparity helps explain the stated rationale: while stablecoins remain Tether’s core business, the company is reallocating resources toward products it sees as attracting more liquidity and sustained participation.

Tether has also been leaning into tokenized gold strategically. Earlier this year, Cointelegraph reported that the market capitalization of tether’s gold token surged when gold hit record highs of a little over $5,300 per ounce, and that the token later pulled back after that peak. Tether also bought a 12% stake in precious metals platform Gold.com for $150 million in February, with plans to integrate XAUT into the platform.

Broader pullback: CNHT and EURT discontinued

Alloy’s wind-down is part of a broader pattern in 2025: Tether has shelved multiple stablecoin products. In February, the company announced it would discontinue its Chinese yuan stablecoin, CNHT, citing “evolving market conditions, low interest in the product, and limited sustained community demand” relative to other supported assets.

Later in the year, Tether wound down its euro stablecoin, EURT, pointing to European regulatory issues and stating that it wanted to direct attention toward other initiatives such as Hadron, its asset tokenization platform launched in 2024.

At the same time, Tether has not entirely stepped away from fiat-linked tokens. In May, it announced plans to launch a Georgian lari stablecoin (GELT) in cooperation with the government of Georgia.

Taken together, the discontinuations suggest Tether is actively pruning products that do not meet internal benchmarks for sustained adoption or regulatory certainty, even if stablecoins remain the company’s core business. Alloy’s wind-down reinforces this approach by removing a specialized collateralized derivative product with comparatively small scale.

Going forward, investors and users should watch whether XAUT’s traction continues to translate into new demand for liquidity tooling around tokenized real-world assets—and whether Tether’s future stablecoin or tokenization launches similarly emphasize regulatory clarity and long-term liquidity, rather than short-lived product experiments.
