Jaredfromsubway.eth, a well-known MEV Bot address long active on the Ethereum network, was targeted in a highly specific on-chain attack on Saturday, resulting in losses exceeding $7.5 million.

Investigations by Blockaid and several on-chain analytics firms revealed that this incident was not a traditional phishing attack or smart contract exploit, but rather a "counter-MEV honeypot attack" specifically designed to exploit the operational logic of MEV Bots.

Over the preceding weeks, the attacker systematically deployed 66 counterfeit token contracts and fake liquidity pools. These assets were meticulously disguised on-chain as major stable assets like WETH, USDC, and USDT, creating seemingly genuine arbitrage trading pathways.

The attack chain unfolded as follows — fake liquidity pools generated signals of "exploitable price gaps"; the MEV bot automatically identified the arbitrage opportunity and executed a trade; during the transaction, the robot granted authorization to an auxiliary contract controlled by the attacker; this authorization was not revoked promptly, leading to persistent exposure of permissions; finally, the attacker triggered a pre-embedded backdoor logic in a single transaction, directly transferring assets such as ETH, USDC, and USDT held by the MEV bot's address.

On-chain data shows that the total scale of assets stolen from Jaredfromsubway.eth this time has exceeded $7.5 million. The attacker subsequently split and transferred some of the assets, further dispersing the fund flow through mixing tools.

Who is Jaredfromsubway.eth? The Most Notorious MEV Bot Address

The reason this attack is so notable now is that the victim, Jaredfromsubway.eth, is itself the most active, most profitable, and most notorious MEV Bot on the Ethereum network (perhaps without even needing 'one of').

"MEV attacks" are essentially a category of on-chain arbitrage behaviors centered around "transaction ordering rights." In the Ethereum network, transactions wait in the mempool to be included in a block before they are confirmed. Block builders or searchers can adjust transaction order, insert transactions, or rearrange transactions within a block to extract additional profits.

The most typical attack type is the "Sandwich Attack"— the attacker inserts a buy order before and a sell order after a user's transaction, profiting from price slippage within a short timeframe. This behavior is extremely common in high-liquidity DeFi trading pairs and constitutes one of the most fundamental profit models within the MEV ecosystem.

Jaredfromsubway.eth is precisely the most representative automated executor of this mechanism. Unlike traditional "single-point arbitrage bots," this MEV Bot operates more like a highly industrialized MEV execution system. It continuously monitors unconfirmed transactions in the mempool, identifies in real-time transaction paths vulnerable to sandwiching, and within an extremely short time window, completes transaction construction, gas bidding, and order insertion, systematically capturing slippage profits.

Data from Cointelegraph Research shows that between November 2024 and October 2025, approximately 60,000 to 90,000 sandwich attacks occurred monthly on the Ethereum network, with about 70% related to Jaredfromsubway.eth's strategy system.

In May this year, when Ethereum co-founder Vitalik Buterin exchanged 26,544 DigitalBits (XDB), his transaction was also precisely targeted and sandwiched by Jaredfromsubway.eth.

There is no official statistic on Jaredfromsubway.eth's historical revenue, but conservative estimates suggest that the address has accumulated tens of millions of dollars in MEV profits during its active periods. During some peak periods, its single-day profits could reach hundreds of thousands of dollars, and it consistently appeared at the top of Ethereum MEV rankings for a long time.

Crypto Security Threats Escalate: Even Top Predators Are Not Safe

While some may marvel at the "hunter finally getting hunted," the hacking of Jaredfromsubway.eth also rings an alarm bell for cryptocurrency risks once again.

In past perceptions, MEV Bots like Jaredfromsubway.eth belonged to the "predator" side of the on-chain ecosystem — they continuously capture slippage and arbitrage opportunities in user transactions through automated strategies, inherently occupying an advantageous position, and could even be considered a representative class of attackers in the crypto market.

But this time, it became the target of design, inducement, and eventual harvesting. Moreover, the attacker did not choose a traditional vulnerability exploitation path. Instead, they constructed a long-running "behavioral trap," allowing the MEV Bot's automated system to proceed step by step towards erroneous decisions while fully complying with its own rules.

It must be admitted that even participants like Jaredfromsubway.eth, who were once most adept at "exploiting the rules," are now exposed to more multidimensional attack surfaces.

It is also worth noting that after the Jaredfromsubway.eth hack, an unknown account on X with 94,000 followers changed its name to Jaredfromsubway.eth and falsely claimed it would "offer a $1 million bounty for the full return of all funds."

Several developers issued risk warnings regarding this, emphasizing that the account is not an official Jaredfromsubway.eth account (the MEV Bot team has no official account) and that it cannot be ruled out that this account might be used for scams in the future. Users are urged to remain highly vigilant.

The Jacobian Conjecture that plagued Yitang Zhang for 7 years was overturned and disproven by Fable 5 overnight

**Summary:** The mathematical community was shocked when the longstanding **Jacobi Conjecture**—a core problem in polynomial mapping that had remained open for 87 years—was reportedly **disproven** by **Fable 5** (an AI model from Anthropic). The conjecture, first posed in 1939, asks whether a polynomial map with a constant, non-zero Jacobian determinant must have a polynomial inverse. Despite seeming intuitive, it had resisted numerous proof attempts by leading mathematicians. The breakthrough came when a researcher, Levent Alpoge, shared a succinct counterexample generated by Fable 5: a specific polynomial map from ℂ³ to ℂ³ whose Jacobian is the constant -2, yet which is not injective (mapping three distinct points to the same image). This elegantly falsifies the conjecture in its general form for dimensions ≥3. The counterexample is simple enough to be verified by hand or with tools like Wolfram Alpha. The event sparked intense discussion, with other AI models like GPT-5.6 quickly analyzing the result and even proposing a refined conjecture. It demonstrated AI's emerging capacity for genuine mathematical creativity, not just pattern matching. The story carries a poignant human dimension: renowned mathematician **Yitang Zhang** had devoted seven years of his early career to this problem under his PhD advisor, using a flawed lemma provided by the advisor. This setback contributed to Zhang leaving academia for years, including a period working at Subway, before his later breakthrough on the Twin Prime Conjecture. The AI's swift resolution underscores the tragic waste of his early effort on a conjecture now shown to be false in higher dimensions. It's important to note the disproof specifically targets the generalized (n-dimensional, n≥3) conjecture. The 2-dimensional case, which Zhang worked on, remains open and is considered mathematically distinct and even more challenging. Nonetheless, the event marks a significant moment, prompting reflections on AI's future role in mathematical discovery.

Bought Bitcoin at $117,000, Sold at $62,000 in Tears: This Company’s Faith Only Lasted a Year

Wall Street's once-hot trend of corporate "Bitcoin hoarding" has hit a painful reality check. Empery Digital, formerly an electric motorcycle company, pivoted to Bitcoin in July 2025, accumulating over 4,000 BTC at an average cost of approximately $117,600 each. As Bitcoin's price plummeted, the company faced massive paper losses exceeding its total market value by early 2026, triggering internal conflict with a major shareholder demanding a sale. In a stark reversal from its earlier refusal to sell, Empery Digital recently sold 1,400 BTC at an average price of $62,000, locking in a significant loss of roughly $77 million on just those coins. The proceeds were used to pay down $10 million in debt, prepare for legal fees related to shareholder lawsuits, and, most notably, fund a new strategic shift: a $65 million investment for a 25% stake in an AI data center facility. This move completes a cycle of chasing market trends—from electric vehicles to Bitcoin treasury and now to AI infrastructure. Empery's case exposes the leveraged nature of the corporate "treasury model," where buying Bitcoin with borrowed money works only while prices rise. Once the asset fell below its cost basis, the company was forced to sell at a loss to service debt and pivot to the next opportunity. The company's remaining assets are 1,514 BTC and its ambitions in AI, demonstrating that its stated "long-term belief" in Bitcoin had a clear price tag: a 50% discount.

Visa Joins the Stablecoin Arena: Not to Eliminate Stablecoins, but to 'Collect Rent' from Them

Visa is entering the stablecoin arena by launching a stablecoin platform, aiming not to eliminate existing stablecoins but to facilitate and profit from their broader adoption. The platform will enable banks, financial institutions, and fintech companies to more easily issue, manage, and integrate stablecoins into Visa's existing global payment network, which spans over 200 million merchants and 15,000 financial institutions. This move is expected to expand the overall stablecoin market by creating more use cases. For USDC (Circle), it presents a short-term benefit due to likely direct integration and its compliance advantages, though long-term competition may increase from bank-issued or consortium stablecoins. For USDT (Tether), the impact could be more significant in traditional payment and settlement areas, as Visa's platform may favor more transparent, compliant options, though USDT is expected to remain strong in pure crypto trading contexts. Regarding Ethereum, Visa's initiative is seen as neutral to slightly positive. It could drive more traditional capital into the Ethereum ecosystem in the form of stablecoins, increasing network activity and demand for Ethereum as a settlement layer, especially with Layer-2 scaling solutions. While the platform will support multiple blockchains, Ethereum's maturity and decentralization make it a likely primary choice for compliant stablecoins. In essence, Visa's strategy is to embrace stablecoins, collect fees from increased transaction volume on its network, and grow the overall market, rather than displace major incumbents like USDC and USDT directly.
