        "content": "Here\u2019s a breakdown of the recent ~US$300 million exploit tied to Aave, what went wrong, and exactly which Aave lending pair(s) suffered losses:\n\n---\n\n## \ud83d\udd0d What Happened\n\n- The vulnerability originated from **KelpDAO**, which stems from a bridge exploit in its cross-chain infrastructure (LayerZero\u2019s EndpointV2). The attacker used this to mint or release approximately **116,500 rsETH** (liquid restaking token), equal to ~$292\u2013$293 million. ([crypto-economy.com](https://crypto-economy.com/aave-borrowing-jumps-300m-exposing-liquidity-stress-after-kelpdao-exploit/?utm_source=openai))  \n- These **rsETH tokens were unbacked**\u2014meaning there was no real collateral behind them. ([forbes.com](https://www.forbes.com/sites/digital-assets/2026/04/18/withdraw-now-inside-aaves-sudden-200m-bad-debt-crisis/?utm_source=openai))  \n- The attacker then **deposited the phony rsETH into Aave** (versions V3 and V4 on both Ethereum mainnet and Arbitrum) as collateral and borrowed *real tokens* against it\u2014primarily **WETH** and **wstETH**. ([forbes.com](https://www.forbes.com/sites/digital-assets/2026/04/18/withdraw-now-inside-aaves-sudden-200m-bad-debt-crisis/?utm_source=openai))  \n\n---\n\n## \u2139\ufe0f Which Aave Pair Lost Money?\n\n- The main pair that resulted in actual loss/bad debt is **rsETH (collateral) / WETH (borrowed)** on **Aave V3 on Ethereum mainnet**. ([forbes.com](https://www.forbes.com/sites/digital-assets/2026/04/18/withdraw-now-inside-aaves-sudden-200m-bad-debt-crisis/?utm_source=openai))  \n- Specifically, the attacker borrowed **52,834 WETH** on Ethereum and **29,782 WETH + 821 wstETH** on Arbitrum using the fake rsETH collateral. Because the collateral was worthless, those borrowed assets represent bad debt. ([forbes.com](https://www.forbes.com/sites/digital-assets/2026/04/18/withdraw-now-inside-aaves-sudden-200m-bad-debt-crisis/?utm_source=openai))  \n\n---\n\n## \ud83d\udcb0 How Much Was Lost?\n\n- Aave is looking at **~US$196\u2013200 million in bad debt** from this exploit. That\u2019s the amount of real, borrowed tokens that Aave can\u2019t recover, because the collateral (rsETH) backing them is fake. ([phemex.com](https://phemex.com/blogs/aave-lost-deposits-bad-debt-kelp-fallout-defi-lending?utm_source=openai))  \n- Meanwhile, the protocol experienced massive panic withdrawals: total value locked (TVL) dropped by **$6\u20138 billion** within hours, even though most other lending pools (those not linked to rsETH) did *not* have exposure incurred losses. ([phemex.com](https://phemex.com/blogs/aave-lost-deposits-bad-debt-kelp-fallout-defi-lending?utm_source=openai))  \n\n---\n\nIf you want, I can also map out which Aave versions (V3 vs V4) on which chains (ETH vs Arbitrum etc.) were affected for non-rsETH pairs or look into what safety mechanisms Aave has (or will have) for covering this kind of bad debt. Do you want me to pull those together?"

They disabled new supplies and prevented any new borrowing against these assets. ([governance.aave.com](https://governance.aave.com/t/rseth-incident-report-april-20-2026/24580?utm_source=openai))  \n- They also **froze WETH borrowing** in several markets (Ethereum Core, Prime, Arbitrum, Base, Mantle, Linea) to stop any additional borrowing against WETH collateral. ([governance.aave.com](https://governance.aave.com/t/rseth-incident-report-april-20-2026/24580?utm_source=openai))  \n- The interest rate models for WETH were adjusted in many markets to make borrowing less cheap at high utilization, helping reduce stress and curtail contagion risk. ([governance.aave.com](https://governance.aave.com/t/rseth-incident-report-april-20-2026/24580?utm_source=openai))  \n\nThese actions aim to contain the damage so it doesn\u2019t escalate into affecting markets beyond rsETH-WETH positions.\n\n---\n\n## \ud83d\udee1\ufe0f Backstop Mechanisms\n\nAave has built-in tools to cover losses (or at least part of them). Here\u2019s how those stack up:\n\n1. **The Umbrella Safety Module**\n   - This replaced the older \u201cSafety Module.\u201d It lets users stake aTokens (e.g. aWETH), which can be slashed to cover bad debt. ([forbes.com](https://www.forbes.com/sites/digital-assets/2026/04/18/withdraw-now-inside-aaves-sudden-200m-bad-debt-crisis/?utm_source=openai))  \n   - BUT: It\u2019s likely *insufficient* to cover the full shortfall (~$190\u2013$200 million), given its available size. ([ccn.com](https://www.ccn.com/education/crypto/kelp-dao-rseth-292m-hack-aave-liquidity-crisis-explained/?utm_source=openai))  \n\n2. **Aave DAO Treasury**\n   - Governance can decide to use treasury funds to help cover deficits. There\u2019s some liquidity already in the treasury, but again, it\u2019s likely not enough on its own for the full amount. ([ccn.com](https://www.ccn.com/education/crypto/kelp-dao-rseth-292m-hack-aave-liquidity-crisis-explained/?utm_source=openai))  \n\n3. **Stakers / Loss Socialization**\n   - If the damage exceeds what Umbrella + Treasury can absorb, there\u2019s a strong possibility that losses get *socialized*\u2014i.e. shared by those who hold relevant aTokens or have staked in the backstop, such as aWETH stakers. ([weex.com](https://www.weex.com/wiki/article/why-aave-froze-rseth-markets-after-the-kelp-dao-exploit-98353?utm_source=openai))  \n\n---\n\n## \ud83d\udea8 Will This Bleed Into Other Asset Pairs?\n\nAs of now, it seems unlikely\u2014if things go well. But there are risk paths.\n\n- The bad debt is currently **concentrated in the rsETH-WETH pair**, on Aave V3 and V4, and on affected chains like Ethereum and Arbitrum. Other lending markets\u2014USDC, DAI, wBTC, and those on chains without rsETH exposure\u2014had *zero direct exposure* to rsETH. ([phemex.com](https://phemex.com/blogs/aave-lost-deposits-bad-debt-kelp-fallout-defi-lending?utm_source=openai))  \n\n- The freeze of rsETH and preventive freezes of WETH borrowing was done precisely to *limit contagion*. So far, no reports show other pairs have been damaged directly. ([governance.aave.com](https://governance.aave.com/t/rseth-incident-report-april-20-2026/24580?utm_source=openai))\n\n---\n\n## \ud83e\udd14 Possible Outcomes: Who Bears What\n\nHere are two main scenarios being discussed.\n\n| Scenario | What Happens | Who Pays |\n|---|---|---|\n| **Uniform Loss Socialization** | Losses spread across all rsETH holders. Aave\u2019s exposure ~**$123\u2013$130M** bad debt. | Aave absorbs through backstops (Umbrella, Treasury), possibly slashing among stakers. Much of the cost might be taken from those who hold rsETH\u2014especially on chains where it\u2019s a simple IOU/wrsETH. ([financefeeds.com](https://financefeeds.com/aave-faces-up-to-230-million-loss-after-rseth-exploit-drains-collateral/?utm_source=openai)) |\n| **L2-Isolated Losses** | Losses mostly borne by rsETH holders on *Layer 2* chains (Arbitrum, Mantle, etc.), with L1 (Ethereum Core) mostly unaffected. Total downside ~$230M. ([governance.aave.com](https://governance.aave.com/t/rseth-incident-report-april-20-2026/24580?utm_source=openai)) | L2 stakers/rsETH holders or KelpDAO/tied backers. Aave Umbrella only protects L1 markets\u2014can\u2019t automatically rescue L2 losses. ([governance.aave.com](https://governance.aave.com/t/rseth-incident-report-april-20-2026/24580?utm_source=openai)) |\n\n---\n\n## \ud83d\udd0e Bottom Line\n\n- **Aave has tools** to backstop much of the loss\u2014but almost certainly *not* enough to completely insulate all affected parties without sacrifice. Umbrella + Treasury won\u2019t fully cover worst-case scenarios.  \n- **Other asset pairs** appear to be safe *for now*. The protocol\u2019s stops (freezing, interest rate changes) were fast. Unaffected markets have not been hit in terms of bad debt.  \n- **Risk will fall on holders of the compromised collateral assets** (rsETH/wrsETH), especially on chains where backing was weak or bridge paths were flawed. Depending on governance decisions, some costs may also touch WETH suppliers and aWETH stakers.  \n\nIf you like, I can pull up exactly how big the Umbrella safety module is, how much is in Aave\u2019s treasury, and estimate what portion of the shortfall remains uncovered\u2014so you can see just how deep the hole might be."
