Crypto trader Rune stated on platform X that the official documentation of PaperTrade has disclosed a "vulnerability" risk in the pricing mechanism at the protocol level. According to the screenshots of the displayed documentation, attackers can manipulate prices using the Best Bid and Offer (BBO) from the Hyperliquid order book. This risk involves unresolved price manipulation pathways, contract economic mechanisms, risk exposure control, as well as operational protective measures and permission management mechanisms.In addition, Rune also forwarded a tweet from community user boblob, which revealed that two wallets are suspected of actively exploiting "attacks" on the PaperTrade platform, causing a slight fluctuation of about 10-20 basis points in the ETH price on the Hyperliquid platform through trades totaling approximately 20 million dollars. Boblob further added that there are obvious issues with the current PaperTrade protocol that need to be fixed as soon as possible, or it may affect the long-term sustainability of the protocol.

According to BeInCrypto, Solana co-founder Anatoly Yakovenko posted on the X platform that he hopes to establish a giant routing on the mainstream trading aggregator Jupiter, converting tokenized Nvidia stocks into tokenized SpaceX (SPCX) via Fartcoin, and believes that this routing will become the national best bid and offer (NBBO) reference price for all brokers in the United States.Yakovenko pointed out that the Jupiter aggregator automatically selects the lowest-cost trading path, and meme coin pools typically have the deepest liquidity on the network, so the router may complete part of the stock trades through Fartcoin.

According to monitoring by Hyperinsight, during the continued pullback of BTC from its peak last night, the whale on Hyperliquid with address 0xc6c chose to go against the trend, going long on 109.7 BTC with 35x leverage, amounting to 8.8 million USD, at an average price of 82,000 USD, with a liquidation line at 80,650 USD.This morning, the downward trend of BTC continued, and the price briefly hovered near the liquidation line, with a price difference of less than 50 USD (about 0.06%). The whale may have given up on closing the position for the first time as most of the funds were already lost on paper. Later in the afternoon, BTC rebounded to around 81,680 USD, significantly recovering on paper, and the unrealized loss narrowed. However, the whale chose to remain inactive again. Ultimately, in the past 10 minutes, BTC faced a large-scale liquidation during a second drop, and then manually stopped out before the next round of liquidation, with the account balance dropping below 100,000 USD.

U.S. Treasury Secretary Scott Basset recently publicly criticized Coinbase on Fox News as a "stubborn participant" for opposing the CLARITY Act. Basset emphasized the necessity of passing the CLARITY Act multiple times during last week's Senate Banking Committee hearing, using strong language against the opponents.It is reported that the CLARITY Act aims to clarify the regulatory division of cryptocurrency assets, with the SEC and CFTC overseeing different areas. However, Coinbase is concerned that it may restrict business models such as stablecoin rewards, leading to divisions within the industry.

According to monitoring by Hyperinsight, the BTC main long address starting with 0x4b6 has continuously faced liquidations in the past two hours, with a total amount reaching 11.46 million USD, among which the largest single liquidation amount was 3.08 million USD, making it the second largest single liquidation scale on the entire network in the past 6 hours.Since opening a long position with a principal of 1.7 million USD on January 19, the address has been continuously "holding the position," and its account funds have now fallen below 100,000 USD. Currently, the 40x leveraged BTC long position has been liquidated by 158 BTC (approximately 11.22 million USD), leaving a remaining position size of only 3.98 million USD, with an unrealized loss of 490,000 USD, resulting in a loss rate of -492%, and it is only 0.54% away from the next liquidation price (70,574 USD). The 25x leveraged ETH long position it holds has also nearly gone to zero in this round of liquidation, with an unrealized loss previously reaching -1134%, equivalent to more than 11 times the principal of the position.

GoPlus Chinese community analyzes the principle of the attack on the decentralized options protocol Ribbon Finance in a social media post.The attacker upgraded the price oracle contract to a malicious implementation contract through the address 0x657CDE, and then set the expiration time of four tokens: stETH, Aave, PAXG, and LINK to December 12, 2025, 16:00:00 (UTC+8) and manipulated the expiration prices, profiting from the exploitation of the erroneous prices.It is noteworthy that when the project party's contract was created, the _transferOwnership status value of the attack address had already been set to true, allowing it to pass the contract security checks. Analysis shows that this attack address was likely one of the project party's management addresses, which was later controlled by hackers through social engineering attacks and other means to carry out this attack.

ChainCatcher news, SMBC Nikko Securities Chief Economist Joseph Lavorgna wrote that recent inflation and labor cost data have raised questions about the wisdom of the Federal Reserve's interest rate cut today.He pointed out that the data released today showed that unit labor costs increased by 3.4% over the past four quarters ending in September, while the core services inflation rate in the third quarter rose by 4.4% year-on-year, well above the Federal Reserve's overall inflation target of 2%. "This makes us wonder why the Federal Reserve is so bold in cutting rates this month," Lavorgna wrote. "Isn't it more prudent to wait and see how the labor market evolves after the hurricane and the Boeing workers' strike? What harm would there be in waiting for clearer data before making a rate cut at next month's meeting?" (Jin Shi)

ChainCatcher message, Federal Reserve Chairman Powell stated: "We have not set any fixed path for interest rates and will make decisions in a series of meetings.

ChainCatcher news, according to 4E Exchange observation, the year-on-year growth rate of the U.S. CPI in August fell to 2.5%, marking a decline for the fifth consecutive month, but the core CPI rose 0.3% month-on-month, exceeding expectations. The market has lowered its expectations for a 50 basis point rate cut by the Federal Reserve next week, with the likelihood of a 25 basis point cut rising to 85%.After the data was released, U.S. stocks experienced a V-shaped rebound following an initial drop at the open, with all three major indices closing higher. The Dow Jones increased slightly by 0.31%, the Nasdaq rose by 2.17%, and the S&P 500 index gained 1.07%. Tech stocks led the rebound, with Nvidia rising over 8%. In the foreign exchange and commodities markets, the U.S. dollar index surged, putting pressure on non-U.S. currencies, while gold experienced significant volatility.CPI data indicates that the Federal Reserve is approaching its 2% target, a change that will support future rate cuts, benefiting risk assets and supporting the long-term rise of U.S. stocks and cryptocurrency assets like Bitcoin. However, the Fed's focus on core inflation may lead to a more cautious monetary policy, limiting the short-term upside potential for the market.4E Exchange is a financial trading platform supporting assets such as cryptocurrencies, stock indices, commodity gold, and foreign exchange, and is a platinum sponsor for Token2049 in 2024. 4E reminds you to be aware of market volatility risks and to allocate assets wisely.
