PANews reported on May 6th that, according to The Block, after suffering a bridging attack worth approximately $292 million last month, Kelp DAO has decided to abandon LayerZero and instead adopt Chainlink's cross-chain infrastructure. Kelp DAO will use Chainlink's cross-chain interoperability protocol, which requires 16 independent node operators to verify cross-chain transactions, making it the first major protocol to leave LayerZero after the attack.

In the attack, LayerZero-powered OFT bridges used a 1-of-1 single validator configuration, and 47% of LayerZero applications at the time used the same configuration. LayerZero subsequently announced the discontinuation of the single validator signing configuration. Kelp DAO stated that migrating to Chainlink CCIP directly resolved the architectural vulnerability in the attack. rsETH will also adopt a cross-chain token standard. As part of the DeFi United rescue effort, LayerZero has donated and loaned approximately 10,000 ETH to Aave.
