NIGHTPreço de Midnight

Wanchain's Cardano-BNB Bridge was exploited due to a cryptographic vulnerability in its TreasuryCheck validator, known as non-injective signed-message encoding. This flaw allowed multiple withdrawal requests to generate the same encrypted message, enabling an attacker to reuse a legitimate signature to authorize fraudulent transactions. As a result, approximately 515 million NIGHT tokens, valued at $9 million, were drained from the bridge's treasury. The stolen tokens were subsequently laundered into ADA on the Cardano network. Wanchain has since halted the bridge and confirmed the incident was isolated, not affecting Midnight's network or Cardano's core blockchain. This exploit is part of a series of recent attacks on cross-chain protocols, though overall crypto losses have reportedly declined year-over-year.

Midnight's NIGHT token plummeted roughly 30% following a $13.2 million exploit on a Wanchain cross-chain bridge. The attacker drained 515 million NIGHT tokens by exploiting a signature reuse flaw in the bridge's infrastructure, not the core Cardano or Midnight networks. This incident highlights the persistent vulnerability of cross-chain bridges, which are critical for asset transfers but introduce complex security risks. While the underlying blockchains remained secure, the token's price suffered due to liquidity disruption and lost market confidence. The response from Wanchain, including pausing the affected bridge and providing clear communication on recovery efforts, will be crucial for stabilizing the situation. The event serves as a reminder for traders to factor in bridge-related risks when evaluating tokens reliant on cross-chain liquidity.

**Crypto & Stock Market Wrap: Bitcoin Tests Resistance, Stocks Retreat After AI Surge** Bitcoin consolidates around $66,000, facing key resistance near $68,000—an area seen as a major psychological and technical hurdle where previous rallies have failed. Analysts note the cryptocurrency is caught between its 200-week moving average (~$63,333) and 200-week EMA (~$68,328). A clear break above $68k is needed to signal a stronger bullish trend, while a rejection could lead to a retest of $63k support. Market sentiment remains cautious, with low futures open interest pointing to a low-liquidity rebound rather than a full bull market. Bitcoin spot ETFs saw another $203 million inflow. US stock futures pointed lower after a strong Tuesday session led by a massive rebound in semiconductors and memory stocks. The rally was fueled by renewed optimism about AI-driven hardware demand, with Micron, SanDisk, and SK Hynix surging. However, those gains reversed in pre-market trading. Super Micro Computer (SMCI) soared over 20% after hours on strong guidance and a record backlog. Other standouts included Rocket Lab and nuclear energy plays Oklo and X-Energy. Rising oil prices (Brent above $91) and climbing Treasury yields (10-year near 4.64%), however, are reigniting inflation concerns and acting as a headwind for equities. In Asia, markets were mixed. South Korea's KOSPI pared early gains to close slightly higher as semiconductor stocks like SK Hynix gave back initial surges. Japan's Nikkei edged lower as the yen hit a fresh 38-year low against the dollar, raising fears of potential market intervention. Key events to watch include the Samsung Galaxy launch, AMD's AI event, and a slew of major tech earnings from Alphabet, Tesla, and IBM after the close on Wednesday, followed by the ECB meeting and Intel's earnings on Thursday.

A "whale" is repeatedly causing interest rate spikes on Aave's USDC pool by temporarily withdrawing nearly $190 million in liquidity every night around 23:30 UTC and returning it within an hour. This action, tracked to a specific Ethereum address, spikes the pool's utilization above its 92% target, sharply increasing variable borrowing rates for all users in the pool during that window. Analysis suggests this is likely a fund performing a daily compliance ritual—withdrawing funds to prove ownership for a snapshot before redepositing them. While the time window for these withdrawals has tightened from June to July, the practice imposes a significant cost. Calculations show this activity costs borrowers in the pool an extra $1.7 million per year. For context, a single $1 million loan incurs about $3,280 in extra annual interest. The transparency of DeFi exposes how traditional financial compliance processes can create a hidden tax for decentralized finance users, highlighting a need for adapted regulatory frameworks.

The Federal Reserve held interest rates steady at 3.50%-3.75% on July 29, marking the fifth consecutive pause since late 2026. While the decision was widely expected, it revealed a significant internal rift. Three FOMC voting members—Hammack, Kashkari, and Logan—dissented, advocating for a 25-basis-point hike. This level of opposition, the first of its kind since 2016, signals persistent hawkish pressure. Chairman Wash, in a post-meeting press conference, delivered a firm message, emphasizing an unwavering commitment to the 2% inflation target and stating the Fed "would not hesitate to act." He announced a substantial shift away from forward guidance, urging markets to interpret economic data independently. Wash also highlighted AI-related capital spending as a key variable, noting its potential dual impact on boosting productivity while potentially pushing up certain prices. Market reaction was pronounced. Stocks fell sharply, with the Dow dropping over 2% for its worst day in 15 months. Long-term Treasury yields surged, with the 30-year yield hitting its highest since 2007, while the dollar weakened and gold briefly rose above $4,100. The combination of internal policy dissent and a shift toward data-dependent communication introduced significant uncertainty into the market outlook.
