Abstract

MoonPay has launched PayBox, a non-custodial payment wallet and storage service that enables users to make transactions directly within AI chatbot dialogues, such as ChatGPT and Claude. To use PayBox, users connect it to an AI model via a connector on the official website. The service then allows for a range of actions, including booking flights, swapping crypto assets, staking, and online shopping—essentially any payment supporting Coinbase's x402 protocol. Upon a user's request, the chatbot constructs the transaction for user confirmation, a process that can be automated with pre-set limits. Support for Gemini and Grok AI models is expected within a month. MoonPay emphasizes security as a top priority, stating that AI agents never have access to user wallet keys, card details, or funds. Keys are secured using Multi-Party Computation (MPC) combined with Trusted Execution Environments (TEE), preventing MoonPay or the AI from independently signing transactions. The service is built on the infrastructure of Sodot, a company acquired by MoonPay in 2026, which secures over $50 billion in assets. PayBox is designed to address common fraud vectors in agent-based payments, such as key theft, card number leaks, and systemic vulnerabilities, by closing each potential attack path individually.

The MoonPay project team has introduced PayBox, a payment vault and non-custodial wallet. The service allows users to conduct transactions without leaving the chatbot dialog window.

To utilize PayBox's features, a user needs to connect it to an AI model via a special connector on the official website. After that, the user will be able to make transactions using the dialog window.

Available functions include booking airline tickets, swapping crypto assets, staking, online purchases, and much more. PayBox enables payments in all services that support the Coinbase exchange's x402 protocol.

Upon receiving a corresponding request, the chatbot forms a transaction, which the user then confirms. Information on the official website suggests this process can be automated by pre-setting limits.

Currently, only ChatGPT and Claude are supported. Support for Gemini and Grok is expected within a month.

According to Neeraj Prasad, Lead Engineer at MoonPay Labs, PayBox provides users with something they haven't had before. If previously agents could suggest, for example, product options, now that list includes the payment itself.

Security is the Key Priority

The project team emphasized that within the service, the AI never has access to wallet keys, card data, or client funds.

Keys, in particular, are protected using multi-party computation (MPC) combined with trusted execution environments (TEE). Neither MoonPay nor the AI agent can access the code or independently sign a transaction.

The service is based on the infrastructure of Sodot, a company acquired by MoonPay in 2026. It secures over $50 billion in assets and more than 10 million wallets for leading crypto companies.

As explained by MoonPay, fraud in the field of agent payments typically occurs under one of three scenarios: theft of keys, leakage of card numbers, or vulnerabilities in the overall system that allow it to be 'broken' entirely.

PayBox is designed to close each of these attack vectors individually, MoonPay stressed.

After R&D Investment Catches Up with the U.S., Is the Sino-U.S. Chip Competition Still Just About Money?

The article examines the significance of recent data showing China's total R&D expenditure, measured by purchasing power parity (PPP), catching up to or slightly surpassing that of the United States in 2024. It argues that while this milestone reflects China's immense capacity to mobilize research resources, the competition in semiconductors now extends far beyond sheer financial input. The analysis highlights key differences: China's R&D is heavily skewed towards experimental development (over 80%), focusing on product engineering and industrialization, whereas the U.S. allocates a proportionally larger share (about 15%) to basic research. Furthermore, leading U.S. semiconductor firms reinvest a significant portion of their substantial global sales revenue into R&D, creating a sustainable commercial innovation cycle that is difficult to replicate. The article emphasizes that semiconductor progress depends on converting R&D into commercially viable products that pass rigorous customer validation and achieve repeat orders, not just on spending levels. It concludes that as China enters the top tier of R&D spenders, the critical challenges shift to improving resource allocation efficiency, fostering long-term basic research, and building effective mechanisms to bridge the gap between laboratory discoveries and reliable, market-ready industrial capabilities.

Walsh: 2% Inflation Target Unwavering, Maintain Independence, Focus on AI Transformation (Full Text Attached)

Fed Chair Warsh emphasized an unwavering commitment to the 2% inflation target, stating there is "no soft target" and that the FOMC is united on this goal. He indicated that if high inflation persists, interest rate hikes would likely be part of the solution. The Fed voted 9-3 to maintain the benchmark rate at 3.5%-3.75%. Warsh announced a significant shift in policy communication, moving away from forward guidance. He noted that market rates have risen between meetings, reflecting a tightening of financial conditions as participants now react more to direct economic data rather than Fed signals. On AI, Warsh highlighted a nearly 20% annual growth rate in high-tech capital expenditures related to artificial intelligence. He acknowledged its potential to boost productivity and supply but also its role in driving up prices for certain sectors like chips and AI infrastructure. The Fed is assessing whether these price pressures will remain sector-specific or spread more broadly. Warsh stressed the Fed's independence, asserting it will not deviate from its mandate due to external pressures. He framed the current decision not as a "pause" but as a period of rigorous review of economic conditions, with future actions to be data-dependent.

Top 10% of American Households Capture 88% of Wealth, How Is the AI Era Cake Divided?

AI Worsens Wealth Inequality as Top 10% of US Families Garner 88% of Stock Gains (2019-2026) A report from the China Finance 40 Forum highlights that the AI boom is significantly widening wealth inequality in the United States. From 2019 to Q1 2026, wealth from directly held stocks by US households nearly doubled from $29 trillion to approximately $55 trillion, with rapid growth concentrated post-2023, coinciding with the AI-driven stock market surge. The distribution of these gains has been starkly uneven. Between 2022 and Q1 2026, the wealth increase of about $21 trillion was captured almost entirely by the wealthiest families: the top 10% secured roughly 88% ($18.5 trillion), while the bottom 50% received only about 1% ($0.2 trillion). This has contributed to a growing disparity in disposable income shares. The report, referencing economic historian Robert Allen, draws parallels to historical technological shifts like the "Engels' Pause" during the First Industrial Revolution, where worker wages stagnated despite productivity gains. It suggests AI could induce a similar period where capital收益 outpace labor income, exacerbating inequality. Huang Yiping of Peking University identifies four mechanisms through which AI impacts income distribution: capital-bias (reducing labor's income share), task polarization (hollowing out middle-skill jobs), skill-based digital divides, and wealth amplification through assets. He warns that if this trend continues, strong supply growth driven by AI could be undermined by persistently weak consumer demand, threatening sustainable economic growth. To address these challenges, the report proposes a three-pronged strategy: 1) Defensive measures like strengthening social safety nets and antitrust enforcement; 2) Empowering workers through education reform and lifelong learning to collaborate with AI; and 3) Rebalancing via policies such as potential taxes on AI超额收益 and mechanisms for broader sharing of technology's benefits, ensuring AI's红利 are more equitably distributed.

Finland to "cut" cables: Russian operators will have to look for new internet routes

Finland will cut the optical fiber communication cables attached to its power transmission line pylons along the border with Russia by 2027, according to its energy company Fingrid. This follows the 2022 halt of electricity imports from Russia, making the infrastructure economically unviable to maintain solely for telecom needs. Currently, about 60-70% of Russia's international internet traffic transits through Finland, with up to 30% of these lines running along the power lines in question. Russian telecom operators are negotiating with Finnish counterparts for alternative routes. Potential backups include lines through Belarus, Baltic states, and submarine cables in the Baltic Sea. While no major impact on user traffic is expected, potential effects include rerouting, reduced network redundancy, and increased latency, especially for users in northwestern and European Russia. An AI analysis notes that shifting to submarine cables introduces new risks, as they are vulnerable to anchor damage and lengthy repairs. This technical move occurs alongside broader trends toward digital autonomy in Russia, raising questions about the future reliability of external internet channels.
