In the wake of a significant cryptocurrency hack that shook the foundations of the decentralized finance (DeFi) world, Coinbase, the United States’ largest cryptocurrency exchange, finds itself embroiled in controversy. The reason? Coinbase has held onto approximately $1 million in profits linked to the incident, sparking a heated debate within the cryptocurrency community and shining a spotlight on the intricacies of asset recovery in DeFi.
The hack, which unfolded on that fateful day in July, exposed vulnerabilities within specific liquidity pools, resulting in the loss of a staggering $73 million in digital assets. This event sent shockwaves across the cryptocurrency landscape, primarily due to Curve Finance’s pivotal role in the Ethereum DeFi ecosystem.
One of the pools affected by the breach contained both ether (ETH) and alETH, an ether derivative issued by Alchemix, a DeFi lending platform. Prior to the hack, this pool boasted 7,259 ETH and 4,822 alETH. Regrettably, the attacker managed to siphon away the majority of these tokens, leaving behind a mere 1 ETH and 3,856 alETH.
The inherent imbalance in the ETH-to-alETH ratio within this pool created an intriguing arbitrage opportunity following the exploit. A vigilant trading bot seized this moment, acquiring the remaining alETH tokens at a substantial discount. Swiftly, these tokens were exchanged for frxETH, another derivative of ETH, and then further transformed into ETH itself. While this astute trading bot pocketed a respectable profit of 43 ETH from these well-timed maneuvers, the lion’s share of the gains flowed towards the validator responsible for processing these transactions. In this particular case, that validator was none other than Coinbase.
This intricate sequence of transactions operates under the banner of “Maximal Extractable Value” (MEV), a strategic approach to ordering blockchain transactions to capitalize on spontaneous trading opportunities. The arbitrage fee paid to Coinbase represented the second-highest MEV payout ever recorded on the Ethereum blockchain.
In the aftermath of the hack, a public bounty and a stern ultimatum successfully coerced the attacker into returning the entire haul of stolen ETH and alETH, amounting to a substantial $22 million, back to Alchemix. Moreover, individuals known as “white hat” actors, acting in good faith, stepped in and restored $13 million worth of assets, a story previously detailed by CoinDesk. In a remarkable display of ethics, a trading bot operator operating under the alias c0ffeebabe.eth voluntarily relinquished the 43 ETH profit accrued from the alETH imbalance.
However, the situation takes a perplexing twist when it comes to Coinbase. The exchange has opted to retain approximately $1 million in profits unintentionally acquired during the hack. Alchemix has taken a principled stance, appealing to Coinbase to reimburse these funds to the victims, underlining that Coinbase knowingly profited from the exploit.
Despite extensive negotiations and discussions, Coinbase remains resolute in its position of neutrality and decentralization, steadfastly resisting calls to return the funds. This decision has ignited a fervent debate within the cryptocurrency community, centered around the ethical obligations of service providers when confronted with criminal activity on their platforms.
This scenario serves as a stark reminder of the intricate dynamics at play in the cryptocurrency realm, where the principles of decentralization often collide with the challenge of establishing accountability and providing recourse for victims of cryptocurrency theft.
