Aztec Network Suffers Attack, Loses Over $2.15 Million, Root Cause Linked to ZK Proof-L1 Settlement Mismatch

2026.06.15 13:26:42

June 15: Per analysis from BlockSec Phalcon (@Phalcon_xyz), Aztec Network’s RollupProcessorV3 contract suffered an exploit resulting in losses exceeding $2.15 million. The root cause lies in numRealTxs not being properly linked to the transaction set enforced by the ZK proof, creating a mismatch between the proof verification process and how L1 settlement logic interprets the transaction list. The attacker exploited this vulnerability to shift valid deposits to slots unprocessed by settlement logic, bypassing the decreasePendingDepositBalance() function to generate unsecured private balances out of nothing, then extracted these funds via standard settlement procedures—with a total of seven assets involved in the incident.

CZ: Supports all meme coins, may trade some meme coins in the coming weeks to test new things.

CZ stated in a post that he did not communicate with the Giggle Academy team about the recent sale of donated tokens, nor does he personally manage the relevant addresses. However, Giggle Academy typically converts or sells most of the donated tokens it receives into BNB at the end of each month. Without a prior agreement or contract, when sending or donating tokens to another party’s address, senders should not expect recipients to handle the tokens according to their wishes—for example, burning them. If you want to interact with another party by sending tokens, you should also be prepared for the possibility that the recipient will sell the tokens. Since the tokens are labeled as donations, recipients should be allowed to use them; one cannot later claim they originally expected the tokens to be burned. Tokens donated to Giggle Academy will be sold, with the proceeds used to provide free education for children worldwide. The project has benefited over 1 million children in less than two years. CZ added that he supports all meme coins and may buy or sell one or two meme coins in the coming weeks to test new initiatives.

European Union Launches AI Super Factory Initiative, Unlocking Over €30 Billion in Investment.

Today, the European Union launched a tender to build up to seven artificial intelligence (AI) super factories across Europe, a key initiative in the bloc’s latest drive to advance European technological autonomy and realize its “AI continent” ambition. Led by industry, the plan is backed by up to €100 billion in funding from the EU and its member states, and is projected to unlock at least €200 billion in private investment across the bloc. The initiative will expand Europe’s AI computing capacity, providing infrastructure for training, inference, and fine-tuning of cutting-edge AI models for startups, growth-stage enterprises, small and medium-sized enterprises (SMEs), industrial players, academic institutions, and public sector bodies. The AI super factories will integrate advanced AI processors, software and cloud technology stacks, high-speed connectivity networks, and energy-efficient data centers. The plan will be combined with Europe’s existing network of 19 AI factories, further strengthening the bloc’s technological leadership, resilience, and strategic autonomy. (Jinshi)

South Korea's NH Investment & Securities maintains a "Buy" rating on SK Hynix, but cuts its target price to 3.4 million Korean won.

South Korea's NH Investment & Securities maintained a "Buy" rating on SK Hynix, but cut its target price from 4.1 million won to 3.4 million won. Citing the HBM4 shipment timeline and faster-than-expected adoption of long-term agreements (LTAs), the firm took a cautious stance and slightly lowered its 2027-2028 earnings forecasts. Even so, the focus remains on the sustainable supply-demand and profit levels brought by LTA implementation, rather than industry downturn cycles. Currently, the market still has high skepticism about the effectiveness of LTAs, so more time is needed for validation. Once the LTA's effectiveness is confirmed by the market, it is expected to drive a re-rating of the company's valuation. Meanwhile, although the company's cash generation capacity has improved significantly, the lack of a clear shareholder return framework remains disappointing. If the company clarifies its capital allocation guidelines, this will serve as a key catalyst for stock price gains. Given the company's still-solid fundamentals, the recent stock pullback has been excessive. SK Hynix reported 79.3 trillion won in sales for Q2 2026, up 256.8% year-over-year (YoY) and 50.9% quarter-over-quarter (QoQ); operating profit stood at 60.5 trillion won, surging 557.2% YoY and 61.0% QoQ. The company's results slightly missed market expectations due to product mix adjustments and the initial implementation of LTAs. Looking ahead to Q3 2026, with HBM4 shipments accelerating, bit growth for DRAM and NAND is projected to rise 10.0% and 1.3% QoQ respectively, while combined average selling prices (ASPs) are expected to increase 16.5% and 7.0% QoQ. SK Hynix is forecast to post an operating profit of 76.2 trillion won in Q3 2026, up 569.6% YoY and 25.9% QoQ.

SK Hynix exited a new $120 million position, with long funding rates rising 37.5% month-over-month.

According to Hyperinsight monitoring, SKHX is currently trading at $921.3, down around 8% intraday, with a 24-hour trading volume of approximately $1.523 billion. Despite the price continuing to decline, capital has not exited; instead, the value of open interest (OI) has risen to about $571 million. Yesterday, SKHX’s OI increased from $443 million to $564 million, a daily rise of roughly $120 million, marking a 27.2% growth. After the price dropped further today, open interest continues to expand, and long position crowding has risen simultaneously. SKHX’s current funding rate is approximately +0.0431% per hour, with a 24-hour cumulative rate of around +0.3948%, a 37.5% sequential increase from the prior 24 hours, further pushing up the cost of long positions. Among whales holding over $1 million in positions, the long-short ratio stands at about 1.24:1, with long positions outpacing short positions by roughly $282 million, meaning both the number and value of positions lean toward longs. However, the closer to top addresses, the weaker the willingness to buy the dip. The overall long-short ratio of all holding addresses is around 4.02:1, but among the top 10 addresses with the largest positions, only 3 are long and 7 are short, bringing the long-short ratio down to 0.43. The top 10 addresses hold a total of about $172 million in positions, accounting for 30.5% of total OI. Currently, SKHX’s dip-buying power is mainly concentrated in long-tail funds.
