Binance hackers conducting large cryptocurrency trades to move stolen funds inadvertently triggered a $119 million loss, with Ethereum validators, block builders, and arbitrage bots capturing the majority of that value between October 29 and October 30, 2024, according to blockchain analysis by Bitquery.
The attackers were converting stolen stablecoins and other assets into ETH and TRX to move funds beyond the reach of stablecoin issuers. Their buying pressure pushed prices in Uniswap’s main WETH/USDT liquidity pool to 38% above the broader market, creating immediate arbitrage opportunities for automated traders.
The scale of the disruption was extraordinary. Ethereum block builders received 10,251 ETH in tips during the frenzy period, compared to 4.6 ETH during an equivalent period the previous night, a 2,200-fold increase. Validators operating through staking services like Lido collected 11,217 ETH across a four-and-a-half-hour window, with block builders retaining 564 ETH after distributing payments to network participants.
Capturing arbitrage profits required priority access to Ethereum’s limited blockspace. Trading bots engaged in bidding wars through the MEV market, competing for the same opportunities. The competition generated 10,251 failed Ethereum transactions during the frenzy, compared to 3,500 failed transactions during the equivalent period the previous night.
Hackers paid $71.5 million above market prices to acquire ETH on Ethereum and $22.4 million above market prices on Tron, where they exchanged approximately 234 million USDT for TRX at unfavorable rates. Trading firms captured $60 million in profits after costs, while Ethereum block builders and validators received $29.5 million in combined payments.
Individual bot operators experienced mixed outcomes. The MEV bot operator jaredfromsubway captured $2.87 million in trading discrepancies but paid $2.95 million in fees, recording a $110,000 loss. An unnamed bot captured $3.24 million in trading opportunities while paying $3.51 million in fees, resulting in an $820,000 loss.
Beyond Ethereum arbitrage, attackers sold stolen tokens including UNI, PEPE, and ENA below market prices, sacrificing an additional $24.8 million. Traders exploiting Tron price discrepancies before fees generated $12.4 million in profits from the hackers’ inefficient conversions.
The hack itself involved approximately $6.3 billion in stolen cryptocurrency, according to prior reporting. The October 30 Bitquery investigation quantified how the attackers’ rushed, high-volume trades created a cascade of extractable value across multiple blockchain ecosystems and MEV infrastructure layers.
