折腾了一个多星期的 Aave 坏账风波已基本迎来尾声。

随着 DeFi United 已募集到了足够解决问题的资金(截至发文已募集 132704 ETH,价值约 3.02 亿美元),Aave 官方也在 4 月 28 日中午发布了关于修复 rsETH 抵押状况并恢复市场正常运行的技术实施方案。

Odaily注:前情提要可参阅《DeFi再次被盗2.92亿美元,这下连Aave都不安全了?》;《2.9亿窟窿下的三方博弈:Aave、L0、Kelp谁能买单?》;《Aave正因自己的愚蠢,拱手让出DeFi借贷的王座》。

背景回溯

关于 Kelp DAO 如何失窃 116500 rsETH 的细节已不用多提,重点在于被盗之后的赃款流向。

黑客得手之后,先是将这 116500 枚 rsETH 分散至多个地址。其中一部分被作为抵押存入以太坊主网上的 Aave V3 并借出 WETH,另一部分被桥接至 Arbitrum 并在该网络上的 Aave 抵押借出 WETH,其余少部分赃款则通过不同渠道转移。

目前,与黑客相关的 7 个地址在 Aave 和 Compound 上仍持有活跃的 rsETH 抵押头寸,约占最初被盗 116500 枚中的 107000 枚。

解决方案

为了实现修复目标,Aave 在拟设的实施方案中设置了两个目标。其一为恢复 rsETH 的抵押支撑;其二为清理 Aave、Compound 等借贷市场中的受影响头寸,以回收约 107000 枚 rsETH 的超额抵押资产,进而修复市场受损情况。

先来说说第一个目标 —— 恢复 rsETH 的抵押支撑。

目前的 rsETH 实质上是属于“资不抵债”状态,虽然底层质押中 ETH 仍然完好,但黑客已通过抵押借贷完成出逃,这部分缺口的存在就导致 rsETH 与 ETH 的兑换报价出现了“脱锚”。

因此 Aave 提到,为了恢复 rsETH 的抵押支撑,就需要将 rsETH 和 ETH 之间的兑换比例拉回到 1 :1.07。这将通过 DeFi United 推动实现,该组织现已获得足够的 ETH 承诺出资,以恢复系统的完整运作,但最终执行仍取决于治理批准、执行时间安排以及相关协议的签署。

若方案能够顺利推进,DeFi United 将通过向 rsETH 的桥接锁仓合约(RSETH_OFTAdapter 0x85d456b2...98ef3)存入 ETH 来完全恢复 rsETH 的抵押支持。具体流程如下:

分批将 DeFi United 的 ETH 转换为 rsETH;
将这些 rsETH 转入相关锁仓合约;
使桥接系统能够安全恢复并全面运行。
LayerZero 和 Kelp DAO 方面会实施额外安全措施,以确保桥恢复后的安全性。

再来看第二个目标 —— 清理借贷市场中的受影响头寸。

rsETH 的抵押支撑恢复之后,理论上 Aave 的借贷市场便已不存在坏账(此时抵押价值已大于借出价值),但仍需将与黑客相关的几个异常抵押头寸清理(预计可回收 13000 ETH),以恢复市场的正常运行。

对此,Aave 表示将在以太坊与 Arbitrum 依次上发起治理提案,通过“受控的清算流程”来清理异常头寸。具体的解决流程为:

暂时调整 rsETH 预言机价格,以触发高效清算;
清算过程中会产生暂时性亏空(后续步骤将弥补该亏空);
回收的 rsETH 抵押品将转移至 DeFi United 管理的多签地址。

Aave 强调,上述参数调整仅为临时措施,仅用于恢复执行,所有调整将在完成后恢复,不会对 Aave 协议造成长期影响。在解决问题期间,以太坊主网、Arbitrum、Base、Mantle 和 Linea 上的 WETH 与 rsETH 存款均将保持冻结状态。

完成清算后的理想状况为:rsETH 价格预言机将恢复; 回收的 rsETH 将通过 Kelp DAO 标准赎回流程兑换为 ETH;这些 ETH 将用于填补 Aave 在以太坊和 Arbitrum 市场中的亏空。

至于 Compound,也将采取类似的清理方式,在 DeFi United 提供流动性支持的情况下,预计可额外回收约 16776 ETH。

待两大目标都有效完成后,Aave 解除所有相关市场中的 rsETH 与 ETH 暂停和冻结状态,随后会恢复 ETH 及其他资产的贷款价值比(LTV)等参数配置。

待解问题

Aave 补充提到,尽管上述方案有望在不出现社会化损失的情况下实现修复目标,但仍存在以下几点不确定性。

一是尽管已获得足够 ETH 承诺,但资金部署仍依赖最终协议与治理批准; 二是受影响头寸的清理依赖治理提案顺利通过与执行; 三是攻击者若刻意干扰,可能导致亏空未完全形成,需要额外清算步骤; 四是LayerZero 与 Kelp 已部署额外安全措施,但在生产环境验证前仍存在残余风险;

但无论如何,已搅扰 DeFi 市场许久的“Kelp DAO 被盗,Aave 坏账”事件看起来终于是要有个尾声了,后续需要看的就是方案能否在实际环境下如预期般推进。

正如 The Rollup 创始人 Andy 的评论:“接下来几天对 DeFi 来说至关重要,任务艰巨,且必须既快速又稳妥地完成。这既是一次技术挑战,更是一场社会协同的考验。能实时见证这一切的发展,确实有种不真实的感觉。”

希望好运站在 DeFi 这一侧。

A New Metric Rainbow Pattern in Bitcoin May Signal the Price!

Bitcoin has fallen to its lowest valuation level according to the Rainbow Chart model, which is based on long-term price trends. Its volatility-adjusted Z-score has also dropped to its lowest level in the past 10 years. Analyst Axel Adler Jr. from CryptoQuant stated that Bitcoin is trading within a range describable as a "fire sale price" on the Rainbow Chart. The current price indicates an extremely steep discount relative to the long-term price trajectory within this model. The Rainbow Chart measures not just Bitcoin's price drop. It compares the current price to the long-term historical trend, showing how far the market has deviated. The adjusted Z-score has fallen to -2.293, the lowest level recorded for this indicator since 2016. During the 2022 market downturn, the score was -1.979. According to the analyst, this indicator, which accounts for volatility fluctuations across different market cycles, suggests Bitcoin's current downward divergence has surpassed the level observed at the bottom of the previous bear market. However, the extremely low valuation does not definitively confirm that a final bottom has been reached. While current prospects point to a potentially attractive price range within the model, confirmation of a market direction change requires data from other indicators. *This is not investment advice.

Ban on Mining Takes Effect in Moscow Region and Kursk Oblast

A ban on cryptocurrency mining has come into effect in Moscow, the Moscow region, and eight border districts of Russia's Kursk region. The decree was signed by Prime Minister Mikhail Mishustin on July 31. In Kursk, the affected areas include the Belovsky, Bolshe-Soldatsky, Glushkovsky, Korenevsky, Lgov, Rylsky, Sudzhansky, and Khomutovsky districts, as well as the city of Lgov. The prohibition will remain in force until December 31, 2032. Moscow authorities have stated that mining consumes a significant amount of energy without benefiting the economy. In the Kursk region, the restriction is attributed to an energy deficit. A similar ban is already in place in 13 other energy-deficient Russian regions, including Irkutsk Oblast, Buryatia, and Zabaykalsky Krai.

Mining Artificial Intelligence: Why Bitcoin Miners Are Changing Their Business Model

"Bitcoin miners pivot to AI: Economic pressures and new opportunities drive business model shift." Major publicly-traded US bitcoin mining companies are shifting their business model away from solely cryptocurrency mining. They are repurposing their infrastructure for artificial intelligence (AI) and high-performance computing (HPC). This move is driven by rising mining costs and declining profitability following the 2024 halving and a 2025 BTC price drop. According to a CoinShares report, the average cost to mine one BTC exceeded its market price in late 2025, making operations unprofitable for many. Companies like IREN, HUT 8, and TerraWulf are now leveraging their existing data centers, power access, and cooling systems to provide infrastructure for AI firms. This transition is facilitated by multi-billion dollar contracts with tech giants; for example, HUT 8 secured a $7 billion deal, and IREN partnered with Microsoft for $9.7 billion. While this pivot requires replacing specialized ASIC mining hardware with GPUs suitable for AI computations, it offers a more stable and potentially lucrative revenue stream. The shift has temporarily reduced Bitcoin's hash rate, but a recovery is expected. Most mining companies' stock prices have risen significantly since the announcement of their AI ventures. Analysts predict that AI-related income could soon constitute the majority of these firms' revenue, fundamentally changing their core business from cryptocurrency mining to AI infrastructure provisioning.

Kerbrat from Robinhood Promotes Tokenization While Memecoins Dominate Its Tokenless L2

Robinhood Crypto's senior vice president, Johann Kerbrat, has emphasized the company's focus on building the technical network infrastructure for tokenization, calling it "just the beginning," rather than on launching tokens. The centerpiece is Robinhood Chain, a tokenless, EVM-compatible layer-2 network built on Arbitrum technology, which settles on Ethereum and uses ETH for gas fees. The network's primary offering is stock tokens, providing 24/7 blockchain-based exposure to companies like Nvidia and Apple for users outside the U.S., though these tokens confer no legal shareholder rights. Despite its focus on tokenized real-world assets (RWAs), currently valued at around $12.81 million, memecoins overwhelmingly dominate trading volume on Robinhood Chain. Research indicates over 99% of trading volume comes from memecoins, with the network's mascot-inspired token, $CASHCAT, surging over 5,500% in a week. Kerbrat, who recently called assets without utility "not a long-term purpose," acknowledged the chain is also "great for memes." The network has seen significant growth since launch. DeFiLlama data shows a Total Value Locked (TVL) of approximately $536 million, a stablecoin market cap of around $634 million, and 24-hour DEX trading volume of about $440 million. Notably, Ethena's USDe stablecoin has grown to constitute nearly 43% of the network's stablecoins. In mid-July, the chain was processing over 7 million daily transactions, surpassing Coinbase's Base. Robinhood is currently covering gas fees for eligible wallet users on swaps, bridges, and perps, but this subsidy is set to end in September. Separately, Robinhood reported Q2 cryptocurrency transaction revenue of $100 million, a 38% year-over-year decline, while its prediction markets generated $156 million, exceeding crypto revenue for the first time.

Explaining 'Liquidation Cascades': How $19 Billion in Cryptocurrency Vanished in One Day

This article explains how "liquidation cascades" led to a $19 billion wipeout in cryptocurrency markets in a single day. It details that most speculation occurs in perpetual futures, leveraged derivative contracts. When prices move against a trader's position, triggering a margin call and automatic sale, it can start a chain reaction. Each forced sale pushes the price down further, liquidating the next over-leveraged position like dominoes, especially when open interest is concentrated at similar price levels. The piece highlights the October 10, 2025 event, where a major geopolitical announcement triggered a massive sell-off. Over 24 hours, leveraged positions worth over $19 billion were liquidated, affecting 1.6 million traders, with long positions making up the vast majority. Total open interest on major exchanges plummeted by 43%. The phenomenon repeated in 2026, with several other "cascade" events causing billions more in liquidations. The article concludes that these cascades are not rare accidents but the market's standard mechanism for shedding excess leverage. The same conditions—high leverage, crowded positions, and clustered stop-loss levels—repeatedly set the stage for these events, with fuel accumulating again after each crash.
