Kelp has accused LayerZero of approving a setup that was exploited in a $292 million bridge hack, allegedly orchestrated by a North Korean hacker group. In response to the breach, Kelp has decided to migrate its rsETH from LayerZero's OFT standard to Chainlink's Cross-Chain Interoperability Protocol (CCIP). This move aims to enhance security and prevent future vulnerabilities in cross-chain transactions.
