Gate News message, April 20, according to Gate market data. As of the time of writing, AAVE (Aave) is trading at $92.32. Over the past 24 hours, it is down 6.53%, with a high of $99.17 and a low of $88.71. The 24-hour trading volume is $16.9544 million. The current market cap is approximately $140.1 million. Aave is an open-source decentralized lending protocol that provides deposit and borrowing services for users. The deposit interest rates for depositors and the loan interest rates for borrowers are calculated algorithmically based on the platform’s borrowing amount and deposit amount. The platform also uses Chainlink oracles to ensure fairness in the collateral price. AAVE’s recent important news: 1️⃣ **Kelp DAO cross-chain bridge hacked, triggering a liquidity crisis** The hacker exploited a LayerZero cross-chain bridge vulnerability to steal rsETH worth $291 million, and then used the illegally obtained rsETH to provide collateral and borrow on Aave, causing the utilization rate of Aave’s core lending pool to reach 100%. The incident triggered a chain reaction: Aave’s net withdrawals totaled $6.2 billion, and total deposits fell from $45.8 billion to $35.7 billion. This event directly hit market confidence and is the main reason for the recent decline. 2️⃣ **Multiple institutions and whales panic-selling** After the incident, multiple whale addresses sold AAVE heavily on-chain, including the "smaugvision" address selling 20,015 tokens, the 0xFC5 address selling 20,000 tokens, and the 0xA2E address selling 19,665 tokens—totaling nearly 60,000 tokens. The well-known whale "ThisWillMakeYouLoveAgain" even cut losses and stopped the loss by selling 29,400 AAVE for $2.73 million, with losses exceeding $6 million. Large-scale selling further intensified downward pressure on the market. 3️⃣ **DAO governance approves a large financing plan to support long-term development** The Aave DAO passed the first grant proposal under the Aave Will Win framework with 75% support. Aave Labs will receive $25 million in stablecoins and 75,000 AAVE (about $6.8 million) unlocked linearly over four years. Founder Stani clearly laid out the strategic direction: all product revenues will flow back to the DAO treasury, with the goal of expanding the protocol’s scale from $40 billion to the trillion-level. This financing plan provides a solid foundation for the protocol’s long-term development, but in the short term the market still needs to absorb the impact of the hacker incident. 4️⃣ **Smart money addresses build positions against the trend** On-chain data shows that over the past seven days, approximately $2.9 million worth of AAVE has flowed out of exchanges. Smart money addresses are accumulating AAVE, with their holdings increasing to 359,880 tokens. The top 100 traders saw a net inflow of $2.18 million, and the leading profit-taking wallets maintained their positions without moving, suggesting that institutional investors are optimistic about Aave’s long-term prospects and providing some support for the current price.

Between 07:15 and 07:30 (UTC) on 2026-04-19, the ETH spot price fluctuated in the 2298.13 to 2322.69 USDT range, with an amplitude of 1.06% and a return of -0.76%. During this period, market attention increased; the sharp drop in price triggered widespread user focus, along with a clear surge in trading volume within a short time, indicating a sudden escalation in liquidity pressure. The main driver behind this deviation is that on-chain whale accounts actively sold ETH to repay DeFi platform borrowings in order to avoid forced liquidation. Based on on-chain tracking and fund-flow monitoring, from April 18 to 19, more than 42,000 ETH per-transaction large transfers were rapidly sent into a certain mainstream exchange, and at the same time there was a sharp spike in net inflows to the exchange. This concentrated sell pressure directly weakened spot market prices. Under proactive deleveraging behavior, selling pressure was released in the short term, creating a sudden market shock. In addition, during the period of price deviation, the ETH derivatives market saw a significant rise in passive liquidation volume, especially as leveraged long positions encountered strong liquidations during the price decline, further increasing supply pressure in the spot market. Meanwhile, ETH spot ETF funds continued to see net outflows; in mid-April, there were multiple days with single-day outflows exceeding $40-50M, with the largest single day reaching $200M. This reflects a warming of short-term institutional risk-avoidance sentiment, which led to a deeper shift downward in buy-side liquidity depth. The launch of a new public chain ecosystem also attracted some ETH liquidity migration, further weakening the capital protection layer of the mainnet. Multiple structural feedback effects amplified the downside move. At present, leverage risk in the ETH market remains prominent. Some whales still have large borrowings outstanding; if the price continues to move downward, potential liquidation risks may flare up again. ETF fund flows, on-chain large transfers, and capital-attraction moves tied to the new-chain ecosystem all need close monitoring. With increased short-term volatility risk, it is recommended to watch key support zones, exchange net inflow indicators, and DeFi on-chain liquidation dynamics in order to promptly grasp the latest market signals.
