虚假或“欺骗”ERC-20 代币转移在以太坊中并不是新鲜事。然而,去年区块链的广泛采用导致这些案例急剧上升。这是一个很常见的问题,我们在两个月前的时事通讯中提供了一个简短的回答,但越来越多的案例和最近的一个备受瞩目的案例需要进行更深入的研究。
在本文中,我们将介绍:

  • 这是什么“欺骗”?
  • 如何检测它?
  • 如何避免它?

想象一下,从大肆宣传的 DeFi 产品中听到即将进行代币空投的传言。你是完美的交易者,你会在区块链上搜索任何关于这种情况发生的迹象。
你瞧,你注意到一个名称和符号与这个 DeFi 产品非常相似的代币是新铸造的。更重要的是,你会看到它被发送到你私下标记为属于人脉广泛的鲸鱼/影响者的地址。
然后该地址将其传输。“这一定是它!”,你想要抢先其他人进入这个代币,你从刚刚创建的 Uniswap V2 流动性池中购买大量代币。一小时后,LP 耗尽所有 ETH,你意识到自己被玩了。
什么地方出了错?

这些代币实际上都不是由乌克兰加密捐赠地址发送的

这些 OpenSea 代币也不是由OpenSea: Registry地址转移的
你犯的错误是认为与你的受信任影响者进行的代币转移实际上是由该地址进行的。这种“欺骗”通过利用以下优势来欺骗毫无戒心的用户:
ERC-20 标准设计

  1. 区块浏览器透明数据展示

ERC-20 标准允许代币具有 transferFrom 功能,允许从与发起交易的地址不同的地址转移代币。
对于 ERC-20 代币传输,Etherscan 等区块浏览器会显示传输代币的地址,而不是发起者地址。由于区块浏览器的性质,默认情况下不会审查区块浏览器的数据。
在大多数情况下,损坏程度仅限于零价值的代币。但可能存在更危险的情况,例如带有还原错误消息的代币,指向钓鱼网站窃取用户私钥。ERC-721 和 ERC-1155 代币 (NFT) 也可能遇到同样的问题。
怎么可能检测到这一点?
答案相当简单。对于这些代币转移中的任何一个,请单击确切的交易哈希并检查其详细信息。发起交易的 From 地址显然与代币转移的 From 地址不同。
要深入挖掘,请在交易输入数据或合约源代码中查找被欺骗的 From 地址。它通常包含在任一位置。

伪造的 OpenSea 令牌看起来好像是由 OpenSea: Registry 在此交易中转移的。
一个关键的警告。并非所有由不同地址发起的代币转移都一定是假的或欺骗的。一个常见的例子是批量发送多个代币传输的 dApp。这些通常有一个由 Etherscan 团队添加的公共名称标签——如果有任何未标记的,请告诉我们
批量发送代币的交易
欺骗代币的近亲是垃圾邮件代币。虽然这些不会假装是由影响者的地址发送的,但它们会被大量发送到该地址,这使得阅读地址的代币标签成为一种悲惨的体验。

筛选Pranksy的代币转移并不好玩……其中许多代币显然也是假的!
可以做些什么来避免这种情况?
对于普通用户来说,没有必要做任何事情,因为这个问题不太可能对你产生太大影响。对于赌徒们来说,停下来问问自己,某件事是否好得令人难以置信,这是明智的。然后查看交易详情页面。
默认情况下,Etherscan 不会审查数据,但我们正在探索帮助缓解此问题的方法。第一步是扩展我们的Token Ignore List的功能。现在的特点:

  1. 自动隐藏 ERC-20、ERC-721 和 ERC-1155 选项卡中的代币转移,并将它们隐藏在地址余额和代币持有量中。
  2. 包括一个简单的选项,用户可以选择忽略所有被 Etherscan 团队标记为可疑或更糟糕的代币。

我们希望此扩展功能有助于保护用户免受欺骗,同时在网站上享受更清洁的用户体验。

The Semiconductor Industry's Most Obscure Chokepoint Material: It Has Multiplied in Price Unnoticed, and China Just Banned Its Export

"Helium: The Silent Choke Point in Semiconductors" Helium, despite being the universe's second most abundant element, is critically scarce on Earth. It cannot be synthesized artificially and escapes Earth's gravity once released, making it a non-renewable resource. Yet, it is indispensable for advanced semiconductor manufacturing, requiring ultra-high purity (99.9999%) for processes like wafer etching, leak detection, and thermal management in lithography tools, with no viable substitutes. This low-profile resource, whose price has doubled unnoticed, suddenly gained attention when China imposed an export ban on July 10th. The ban is a response to a severe global shortage triggered months earlier. In March, missile attacks damaged the world's largest helium production hub in Qatar's Ras Laffan, halting a third of global supply with repairs expected to take 3-5 years. Concurrently, Russia tightened export controls, and the US sold off its federal helium reserve. Approximately 200 specialized transport containers, each worth ~$1 million, were stranded with perishable cargo. Global spot prices skyrocketed, and chipmakers like TSMC warned of potential impacts. China, which imports over 84% of its helium (primarily from Qatar and Russia), faces a severe squeeze. Despite being helium-poor, China has developed domestic extraction technology over five years, processing byproduct gases from LNG plants to produce ultra-pure helium. Domestic output, while still only covering less than 20% of demand, enabled the recent export ban aimed at securing domestic supply for its own expanding chip industry. The industry now faces "Helium Shortage 5.0." With key global sources constrained for years, this invisible gas—once wasted on party balloons—has become a critical, geopolitically charged bottleneck for chips, healthcare (MRI machines), and beyond, forcing the world to finally treat it as the finite strategic resource it is.

Early Investor of Unitree Bets on a Brain-Computer Interface Company

"Wabo Technologies, a brain-computer interface (BCI) startup, has secured new funding from Vertex Ventures (under Temasek), Hongtai Fund, Chengdu Future Industry Fund, and Huifengda Capital. Vertex Ventures is known for its early bet on Unitree Robotics. Inspired by the sci-fi film "Avatar," founder Zhang Xingzhi has pursued human-machine interaction for over a decade. He established Wabo in late 2025, coinciding with China's push for BCI as a future industry. Unlike companies focused solely on medical hardware, Wabo positions itself as a model company. Its core mission is to develop a "Human Neural Intent Model" that decodes EEG, EMG, and behavioral signals to understand a user's goals, confirmations, corrections, and stop intentions before physical action, translating them into standardized control signals for machines, robots, or smart devices. The young, full-stack team, backed by academic collaborators from Tianjin University and Fudan University, quickly attracted investors. The company had previously raised a seed round from Ceyuan Capital. Investors were impressed by Wabo's systematic capabilities in data collection, signal processing, and engineering, seeing potential beyond a single hardware product toward a reusable layer of human intent interpretation. Applications span medical rehabilitation, smart homes, embodied AI, and even space exploration, with Wabo partnering with Tianjin University on pioneering "space BCI" research. Wabo plans a dual-headquarters strategy, with Shanghai focusing on high-end R&D and model development, and Chengdu handling hardware, product development, and supply chain. The BCI sector in China is heating up, with over 30 financing deals in early 2026. Zhang believes future competition will center on who can build a sustainable data-model-scenario loop. He predicts industry consolidation within three years, with only companies that master this闭环 surviving. The vision from "Avatar" is inching closer to reality."

ChangXin Technology: A Cyclical Stock Standing Atop the Cycle Peak

Changxin Technology: A Cyclical Stock at the Peak On July 27, 2026, Changxin Technology topped the A-share market with a market capitalization of 3.28 trillion yuan, surging 465% on its first trading day. The company, which lost 16.3 billion yuan in 2023, reported an estimated net profit of 50-57 billion yuan for the first half of 2026. Its dramatic reversal mirrors the volatile DRAM (Dynamic Random Access Memory) cycle. The DRAM industry is inherently cyclical, with booms and busts every 3-4 years. This is due to product standardization and a significant time lag in supply adjustment. When prices rise, manufacturers expand capacity, but new production takes 2-3 years to come online, often leading to oversupply and price crashes when demand cools. Changxin's performance perfectly tracks this cycle. It recorded deep losses in 2023-2024 during the industry downturn, turned its first annual profit in 2025, and saw profits skyrocket in Q1 2026. This surge is primarily price-driven. The AI boom has led major players like Samsung and SK Hynix to shift 70-80% of new capacity to high-margin HBM (High Bandwidth Memory), creating a severe shortage and price explosion in general-purpose DRAM markets where Changxin competes. However, a massive global capacity expansion is underway. The top three manufacturers have announced nearly $70 billion in capital expenditure for 2026. Changxin itself plans to expand from three to seven 12-inch wafer fabs. This investment will translate into significant new supply in 2-3 years. While DRAM prices are expected to remain high through 2026-2027, price growth is already slowing, and a potential downturn is forecast for around 2028 as new capacity ramps up. A key challenge for Changxin is catching up in the critical HBM segment. While it has delivered HBM3 samples, leaders are already mass-producing more advanced HBM3E. Success in HBM is crucial for gaining true cyclical resilience. In conclusion, Changxin is a commendable company that has broken foreign monopolies in DRAM. Its long-term growth narrative—driven by import substitution and AI—is valid. Yet, its current valuation of 5-6x forward P/E, typical for a cyclical stock at its peak, suggests much future growth is already priced in. AI may extend the current cycle but cannot eliminate the industry's inherent volatility. For investors, the critical question is preparedness for the inevitable downturn when the cycle turns.
