Analysis of 2,665 LayerZero OApp contracts shows nearly half rely on single-validator security configurations, the same setup that exposed KelpDAO’s rsETH to exploitation.
Dune Analytics published an open analysis on Monday examining Decentralized Validator Network (DVN) security configurations across ~2,665 active OApp contracts on LayerZero over the past 90 days. The research found that 47% of OApps operate with a 1-of-1 DVN security floor—the most minimal configuration requiring only a single validator—while 45% use 2-of-2 configurations and approximately 5% employ 3-of-3 or higher. KelpDAO’s rsETH token, which was targeted in a recent exploit, fell into the 1-of-1 bracket.
The analysis provides open-source methodology and queryable data, inviting community feedback on DVN security standards across the LayerZero ecosystem. The findings highlight structural vulnerabilities in cross-chain bridge security, as single-validator configurations create single points of failure for protocol assets and user funds routed through LayerZero’s omnichain infrastructure.
