The attacker behind the $61 million July 30 Curve Finance attack has returned 4,820.55 Alchemix ETH (alETH), worth approximately $8,889,118, to the Alchemix Finance team and 1 Ether (ETH), approximately $1,844, to the Curve Finance team. The Alchemix Finance protocol alETH-ETH pool on Curve is one of the pools originally exploited.
The Curve Finance protocol was attacked through a reentrancy bug on July 30, and over $61 million worth of crypto was lost in the attack. The exploit affected the Alchemix Finance alETH-ETH, JPEG’d pETH-ETH and Metronome sETH-ETH pools. The JPEG’d pool, in particular, was front-run by a miner extractable value (MEV) bot, causing the proceeds from the attack to go to the bot instead of the attacker. The emergency mutisignature wallet suspended all rewards for affected pools on Aug. 2.
