Kelp DAO points to LayerZero's default "1 out of 1" validator config as the root cause of the $290M bridge hack. Attackers compromised 2 LayerZero servers, rerouted DVN traffic, and stole ~116.5k rsETH. Kelp DAO had discussions with LayerZero about DVN config in July but no explicit change requests were made. LayerZero's docs showcase 1/1 as default, used by ~40% of integrations. Kelp's core restaking contracts remain secure.
