Coinbase’s Base Unveils New Infrastructure For AI-Controlled Crypto Wallets

Only $1.1 million in transaction volume has passed through Coinbase’s x402 payment protocol in the past 30 days. That number tells a lot about where AI-driven crypto payments actually stand right now. A New Layer For Crypto Transactions Base, the Ethereum layer-2 network operated by Coinbase, has rolled out a tool that lets AI agents carry out blockchain operations directly from a chat interface. Called Base MCP, the system works with AI models including Anthropic’s Claude and OpenAI’s ChatGPT, allowing users to transfer funds, swap tokens, check balances, and pull up transaction history without leaving the conversation window. The tool also connects to a range of crypto apps, including Morpho, Moonwell, Uniswap, Aerodrome, Avantis, Bankr, and Virtuals. Users interact with these platforms through the AI agent, which proposes actions that must then be approved by the user through a separate wallet window. The agent has no access to private keys. Confirmation Required Before Funds Move Lincoln Murr, Coinbase’s head of AI Product, described Base MCP as a wrapper on top of existing APIs. He told Fortune that unlike standalone agentic wallets confined to a terminal, the Base account syncs across both in-agent and in-app activity, carrying a user’s trade history and portfolio wherever they go. Base said every proposed transaction goes through the same review process users see with standard Base account requests. Asset changes are simulated before the user confirms anything. No funds move without a deliberate approval step. The launch is also expected to drive more activity through x402, the agentic payment standard Coinbase introduced in May 2025. The protocol is designed to let AI agents make small crypto payments as part of a broader micro-transaction economy. Data shows that economy is still getting started — x402 has processed just $1.1 million in volume over the last 30 days, according to x402scan. Security Researchers Flag Risks Not everyone is convinced the infrastructure is ready for wider use. A research paper from Google and several universities concluded that AI agents should be treated as untrusted components within any system. The research warns that bad actors can manipulate agents by embedding hidden instructions inside data the agent processes. Those concerns are not purely theoretical. The developer platform Socket recently uncovered malware targeting crypto developers that worked by injecting concealed instructions into AI coding tools to redirect their behavior. Reports indicate that Base MCP supporters argue the confirmation step addresses the core risk, but researchers say the problem runs deeper than any single safeguard can fix.

Columbia Professor: Stellar, Not Ethereum, Is the Right Fit for Global Finance

BitcoinWorld Columbia Professor: Stellar, Not Ethereum, Is the Right Fit for Global Finance A Columbia Business School professor has cast doubt on Ethereum’s suitability as a global financial backbone, arguing that the Stellar network (XLM) is better aligned with the needs of mainstream finance. The commentary from Austin Campbell, an adjunct professor, follows a major announcement by the U.S. Depository Trust & Clearing Corporation (DTCC) to tokenize its custodial assets on the Stellar blockchain. Why Stellar Over Ethereum? In a series of posts on X (formerly Twitter), Campbell explained that the choice of Stellar for the DTCC project was not arbitrary. He stated that while Ethereum prioritizes censorship resistance, this very feature makes it incompatible with the requirements of regulated global finance. “Censorship-resistant money and the mainstream global financial system are fundamentally incompatible,” Campbell wrote. He elaborated that decentralization carries real operational costs that often outweigh its benefits for institutional use. Stellar, by contrast, offers open access while employing a trust-based consensus algorithm. This design allows financial institutions to select their transaction partners directly, a critical feature for compliance and risk management. Control Features in a Public Ledger Campbell highlighted that Stellar’s Layer 1 protocol supports essential control functions that are non-negotiable for large financial entities. These include the ability to freeze assets, seize funds, and maintain whitelists of approved participants. To become mainstream financial infrastructure, he argued, a ledger must be open for participation but also possess the capability to block malicious actors. This pragmatic approach contrasts sharply with the ethos of many public blockchains that prioritize absolute decentralization. The professor’s comments add a nuanced layer to the ongoing debate about the future of tokenized real-world assets (RWA). DTCC’s Tokenization Plans The DTCC, a critical backbone of U.S. capital markets, recently announced its intention to tokenize custodial assets on the Stellar network. The project has a target launch in the first half of 2027. This selection by such a central market infrastructure player gives significant weight to Campbell’s argument that Stellar’s design is more practical for institutional adoption. Implications for the Crypto Market This development signals a potential shift in how major financial institutions view blockchain technology. The preference for a network that balances openness with control suggests that the future of tokenized assets may not belong to the most decentralized networks, but to those that can most effectively bridge the gap between blockchain innovation and regulatory reality. For Ethereum, which has long been considered the default platform for decentralized finance (DeFi) and tokenization, Campbell’s critique represents a significant challenge. It raises questions about whether its core design principles are a strength or a liability when courting institutional capital. Conclusion The debate between idealistic decentralization and practical compliance is now playing out in real time with major financial players. Austin Campbell’s analysis, grounded in the DTCC’s concrete decision, provides a clear argument for why networks like Stellar may be better suited for the future of global finance. The coming years will reveal whether the market agrees with this vision. FAQs Q1: Why did the DTCC choose Stellar over Ethereum for tokenization? According to Professor Austin Campbell, Stellar was chosen because it offers open access while using a trust-based consensus algorithm that allows financial institutions to select partners directly. It also supports control functions like asset freezes and whitelisting, which are essential for regulatory compliance. Q2: What is the main criticism of Ethereum for global finance? The main criticism is that Ethereum’s core principle of censorship resistance is incompatible with the requirements of mainstream global finance, which needs the ability to block malicious actors and comply with regulations. Q3: When is the DTCC’s Stellar project expected to launch? The DTCC has announced a target launch for the first half of 2027 for tokenizing its custodial assets on the Stellar network.

Whale Address Tied to Shapeshift Founder Erik Voorhees Buys $1.35M in ETH

BitcoinWorld Whale Address Tied to Shapeshift Founder Erik Voorhees Buys $1.35M in ETH A cryptocurrency whale address suspected of being linked to early Bitcoin adopter and Shapeshift founder Erik Voorhees has made a significant purchase, acquiring 668 ETH valued at approximately $1.35 million within the past hour, according to blockchain tracking firm Onchain Lens. This latest transaction brings the address’s total Ethereum holdings to 139,882 ETH, worth an estimated $281.73 million at current market prices. Who is Behind the Whale Address? While the address has not been officially confirmed as belonging to Voorhees, blockchain analysts have long associated it with the Shapeshift founder and early cryptocurrency advocate. The address has been consistently active over the years, accumulating large amounts of Ethereum during various market cycles. The recent purchase adds to a pattern of accumulation that has drawn attention from the crypto community, particularly as it occurs amid broader market uncertainty. Implications for the Ethereum Market Large-scale purchases by known or suspected high-net-worth individuals often signal confidence in an asset’s long-term value. In this case, the acquisition of over $1.3 million in ETH during a period of fluctuating prices may indicate that influential market participants view current levels as attractive entry points. However, it is important to note that single whale transactions, while notable, do not necessarily predict broader market movements. Why This Matters to Crypto Investors For everyday investors and traders, monitoring whale activity can provide insight into market sentiment. Accumulation by large holders often precedes price stabilization or upward trends, though this is not a guaranteed outcome. The transparency of blockchain transactions allows for real-time tracking of such moves, offering a level of insight not available in traditional financial markets. Still, readers should avoid making investment decisions based solely on whale activity, as market dynamics remain highly volatile. Conclusion The purchase of 668 ETH by an address tied to Erik Voorhees adds to a growing narrative of high-profile accumulation within the Ethereum ecosystem. While the move reinforces confidence among some market participants, it also underscores the need for cautious analysis in a sector known for rapid price swings. As blockchain data continues to provide transparency, the actions of major holders will remain a key point of interest for the crypto community. FAQs Q1: Who is Erik Voorhees? Erik Voorhees is a well-known figure in the cryptocurrency space, best known as the founder of Shapeshift, a non-custodial cryptocurrency exchange. He is also an early Bitcoin adopter and outspoken advocate for decentralized finance. Q2: How was the whale address identified? The address was flagged by blockchain tracking firm Onchain Lens, which monitors large transactions and associates them with known entities based on historical activity and public blockchain data. The link to Voorhees is based on patterns and prior reporting, not official confirmation. Q3: Should I buy ETH because of this whale purchase? No. While whale activity can be informative, it should not be the sole basis for investment decisions. Cryptocurrency markets are highly volatile, and individual transactions by large holders do not guarantee future price movements. Always conduct your own research and consider your risk tolerance.

Grayscale Adds Staking Feature to Its Hyperliquid ETF Filing

BitcoinWorld Grayscale Adds Staking Feature to Its Hyperliquid ETF Filing Grayscale Investments has taken a notable step in the evolving cryptocurrency exchange-traded fund (ETF) landscape by amending its proposed Hyperliquid ETF to include a staking component. The firm filed a Form 8-A with the U.S. Securities and Exchange Commission (SEC) on May 27, formally registering securities for the newly renamed Grayscale Hyperliquid Staking ETF. Background and Filing Timeline The move follows an earlier Form S-1 prospectus submitted to the SEC on May 21, which outlined the fund’s initial structure. By transitioning to a staking ETF, Grayscale is positioning the product to generate yield from the Hyperliquid blockchain’s proof-of-stake mechanism, a feature that could appeal to investors seeking passive income from their crypto holdings. The Form 8-A is a standard step for registering securities under the Securities Exchange Act of 1934, signaling that Grayscale is preparing for a potential public listing. Implications for the Crypto ETF Market Staking ETFs represent a relatively new frontier in regulated crypto investment products. Unlike traditional ETFs that simply track asset prices, staking funds can earn additional tokens by participating in network validation, potentially offering higher returns but also introducing additional risks related to network slashing and validator performance. Grayscale’s decision to rename and refile its Hyperliquid product suggests a strategic bet that the SEC may be more receptive to staking features in ETFs, especially after recent approvals of spot Bitcoin and Ethereum funds. What This Means for Investors For retail and institutional investors, the Grayscale Hyperliquid Staking ETF could provide a regulated avenue to gain exposure to Hyperliquid (HYPE) while earning staking rewards without the technical complexity of running a validator node. However, the fund’s ultimate approval remains uncertain, as the SEC has historically scrutinized staking-related products over concerns about securities classification and investor protection. The filing also reflects a broader trend of asset managers integrating blockchain-native features into traditional financial vehicles. Conclusion Grayscale’s filing for a staking-enabled Hyperliquid ETF marks a significant development in the convergence of decentralized finance and regulated investment products. While the path to SEC approval is unclear, the move underscores growing demand for yield-generating crypto funds and could set a precedent for similar filings in the future. Investors should monitor regulatory updates closely as the review process unfolds. FAQs Q1: What is the Grayscale Hyperliquid Staking ETF? A: It is a proposed exchange-traded fund by Grayscale that would invest in Hyperliquid (HYPE) tokens and generate additional returns through staking rewards from the Hyperliquid blockchain’s proof-of-stake network. Q2: Why did Grayscale rename its ETF to include staking? A: The renaming reflects the addition of a staking feature, which allows the fund to earn yield by participating in network validation. This could differentiate the product from standard crypto ETFs and attract investors seeking income. Q3: What is the current status of the SEC filing? A: Grayscale submitted a Form 8-A on May 27 for securities registration, following an earlier Form S-1 prospectus on May 21. The SEC has not yet approved or denied the fund, and the review process is ongoing. This post Grayscale Adds Staking Feature to Its Hyperliquid ETF Filing first appeared on BitcoinWorld .

Google engineer allegedly had a cheat code for Polymarket and turned it into $1.2M

Federal prosecutors have charged a Google software engineer in a case involving alleged insider-style trading on the blockchain prediction platform Polymarket. According to federal prosecutors, 36-year-old Michele Spagnuolo knew the results months before anyone else. He was arrested on May 27, 2026. The US Attorney’s Office for the Southern District of New York released a criminal complaint that charges him with commodities fraud, wire fraud, and money laundering. Google holds an annual “Year in Search” campaign, where it reveals the most-searched people, events, and topics, and people usually bet on the results before they come out. What is Polymarket, and how does someone make money on it? Polymarket is an online prediction market where people bet on the occurrence of real-world events . It uses a simple yes-or-no system in which each “YES” and each “NO” is priced between 0 and 1 dollar. The price changes depending on what other traders think the odds are. For example, if there is a 90% chance that Donald Trump will NOT be the top-searched person, then the “NO” share for Trump trades around 90 cents. That means if Trump is indeed not the top result, and you had bought that share, you would make 10 cents per share, as each share pays out a full dollar. It is a guessing game for many traders because the system relies on assumptions, but Spagnuolo allegedly already knew the answer. What is Google’s Year in Search, and why are the results hidden? The “Year in Search” is a list of the people, events, topics, and questions that trended most on Google’s search engine during that year. The company has released the list since at least the early 2000s. According to the criminal complaint filed by FBI Special Agent Brandon Racz, the campaign has many benefits for Google. It drives millions of people to Google’s platforms and generates significant media coverage for the organization. It also reinforces Google’s status as the “authoritative barometer of public interest and cultural trends,” and gives Google a high-profile showcase to demonstrate its reach to advertisers. Google keeps the results a secret, even to most of its employees. If the results leaked early, the media buzz would disappear, advertisers would lose interest in the launch moment, and the entire marketing campaign would be undercut. Google treats this information as highly confidential and restricts the data to a small number of employees. Spagnuolo has access to the data. Which bets did Spagnuolo make? Polymarket opened two markets for the 2025 Year in Search on October 14 and 20. The first market listed about 24 people and asked which of them would be the most-searched person on Google for 2025. The second market asked whether those same people would be in the top five. The payout depended on the results that Google would publish on the Year in Search website. Spagnuolo allegedly accessed Google’s internal Year in Search tool and used an anonymous account named AlphaRaccoon to place a $403 on Kendrick Lamar as the top-searched person. The odds for that were 3%, and Google’s internal Year in Search tool already has Lamar’s name. He also bet $10,807 that Pope Leo XIV would NOT be number one, just as the list indicated. The market gave Pope Leo XIV a 50/50 chance. Spagnuolo checked the internal tool again on November 27 and saw that a musician named d4vd had replaced Kendrick Lamar as the number-one trending person for 2025. He AlphaRaccoon bet $381.12 that d4vd would be in Google’s top 5, with a market outcome of only 18% because most traders had no idea who d4vd was in the first place. The Italian also bet $5 bet that d4vd would be the single top-searched person. The market assigned a near-zero probability to that outcome, so it was basically free money for him. But the biggest bets were $937,688 that Bianca Censori, $613,587 that Pope Leo XIV, and $509,149 that Donald Trump would NOT be number one. He also added $171,612 that Donald Trump would NOT be in the top five. AlphaRaccoon risked about $2.75 million on about 25 outcome bets. Google published the results on December 4, and d4vd, Kendrick Lamar, Jimmy Kimmel, Tyler Robinson, and Pope Leo XIV made the Global Top 5. How did the FBI find Spagnuolo? Spagnuolo tried to hide all traces of the money by converting his winnings into different cryptocurrencies and running them through a service designed to erase transaction history on the public blockchain. However, the FBI traced each address and found that the same wallet belonging to AlphaRaccoon was responsible for these transactions. Here is what the US criminal complaint, Southern District of New York, stated in May 2026, “Unlike the counterparties to his trades, Spagnuolo knew the outcome of these wagers before the trading public did because he had accessed Google’s confidential, commercially valuable internal data.” How did Google respond? A spokesperson at Google published a statement after Spagnuolo’s arrest and said, “We’re working with law enforcement on their investigation. The employee accessed our marketing material using a tool available to all employees, but using such confidential information to place bets is a serious breach of our policies. We’ve placed the employee on leave and will take the appropriate action.” However, the statement contradicts the complaint. Google says the tool was available to all employees, but the criminal complaint states that Year in Search data is restricted “to only a limited number of employees” even within the company. This is the second major insider-trading incident connected to Polymarket in 2026, which is putting serious pressure on the market regarding this kind of abuse.
