Ethereum Exploit Hits TrustedVolumes for $5.87M

A major DeFi security incident has unfolded on the Ethereum blockchain as TrustedVolumes, an independent market maker used by multiple DeFi protocols, suffered a $5.87 million exploit.

According to Blockaid, a blockchain security firm, the attack targeted a TrustedVolumes resolver contract tied to RFQ swap execution infrastructure on Ethereum. The attacker wallet identified by researchers extracted around $5.87 million in digital assets, including approximately 1,291 WETH, 206,000 USDT, nearly 17 WBTC, and more than 1.26 million USDC.

The exploit seems to be linked to a custom RFQ swap proxy controlled by TrustedVolumes rather than any core 1inch protocol infrastructure. Security researchers have connected the exploiter address to the March 2025 Fusion V1 incident that previously impacted liquidity execution systems within the broader 1inch ecosystem, although Blockaid stressed this latest exploit involves a separate vulnerability.
