- Ethereum mainnet witnessed four separate smart contract exploits within a 48-hour period, resulting in cumulative losses exceeding $1.5 million.
- The ETH price tested holding $2,250 support and as a 20-and-50-day exponential moving offer a dynamic support to buyers.
- The crypto fear and greed index at 33% accentuate the intact bearish sentiment among market participants.
The recent Kelp DAO rsETH exploit has raised the market awareness on vulnerabilities of the DeFi ecosystem. Attracker has started utilizing autonomous AI agents to find and execute vulnerabilities in seconds, which means traditional human audits are no longer enough. To survive this, industry must evolve from static security models to active, AI-integrated defense systems to close the exploit window and reclaim the stability of the digital economy.
Ethereum Smart Contract Vulnerabilities Lead to $1.5M Theft
Over the past 48 hours, four smart contract attacks occurred on Ethereum mainnet, resulting in more than $1.5 million in cryptocurrency losses.
One attack involved an on-chain aggregator. The hackers stole approximately 429 ETH (equivalent to $983,000 at the time) by swapping 384 yvWETH. The attack was made possible by a lack of access controls in an execute function and an open approval from the victim to the contract. Details of the attack can be seen on Etherscan at 0xebaaab69baa3cd2543eb80ecfb8e3ed226b9e5a6f5694891a8adf4edbcbd8107.
The second attack targeted a third-party vault contract connected to TradingProtocol. The attack resulted in a loss of $398,000. The root cause is believed to be inadequate permission checks. The associated transaction hash is 0x6b04344d5627df59d3bc645e7454f4605a90272852a91e435e370376643353b3.
Another attack was based on a reentrancy attack of the BCB contract. Some $39,800 was stolen before the mechanism kicked in. The exploit transaction is logged as 0x879b365b169dbf79c7f6fc7c2f7fd57eb1e53f0be8cf97ed817a7ff3d2e0ba69.
In the fourth attack, QNT tokens worth $124,900 were stolen. The hackers exploited an arbitrary call vulnerability related to EIP-7702 inside an unprotected BatchCall implementation. The transaction reference is 0x4f31f68df9f240492f13df9ab23207ea231ec1b5a89af9c31cde58e7d98cb18c.
The incidents took place in a short time frame on the Ethereum network. The events highlight the narrowing gap between the discovery of vulnerabilities and their exploitation, which seems to have shifted from days to hours to minutes or even seconds due to the use of sophisticated tools, such as AI, to understand the code. The attacks underscore issues in permissioning, reentrancy, and the handling of external calls in deployed contracts.
In a recent tweet, decentralized security infrastructure GoPlus Security (GPS) highlighted their attempt to prevent these attacks with an AI-driven smart contract vulnerability discovery engine called Deepscan. Their security system plans to use graph analysis, dynamic fuzzing, LLM workflows, and continuous auditing to provide efficient, lifecycle smart contract security.

Key EMA Support Holding ETH Price From a +20% Fall
Despite the aforementioned attack, the Ethereum price showed notable resilience above the $2,250 support. The Ethereum price is up ETH0.00% ahead of U.S. market hours on Wednesday to currently trade at $2,390.
The 20-and-50-day EMA slopes are offering additional support to buyers, maintaining the short-term recovery trend. If the bullish momentum persists the price of Ethereum could jump 9% and challenge the resistance trendline of inverted flag pattern.
A potential breakout from this barrier will invalidate the bearish pattern, and bolster ETH for rally towards $2,721 and $3,000.
On the contrary, if the coin price loses the EMA support, the sellers could drag the coin another 6.5% to retest the flag support. A bearish breakdown from this floor would strengthen the sellers grip over this asset and drive a prolonged downtrend $1,745.
