最新报道:Coinbase VP Conor Grogan revealed a shocking $480,000 Ethereum transaction fee paid by a user who accidentally burned 112,745 ETH (worth $400M at the time) in 2019. The massive fee occurred due to a coding error in a smart contract that set the fee equal to the transaction amount. Grogan noted the incident highlights Ethereum's "unforgiving" nature, as the funds were permanently lost. While rare, such mistakes underscore the risks of blockchain transactions where errors can't be reversed. The case remains one of crypto's most expensive mistakes, demonstrating the need for careful coding and transaction verification in DeFi operations.
