On-chain analysis by Dune on April 21, 2026, revealed that nearly half of LayerZero OApps used the 1-of-1 DVN setup, the lowest security tier. The report cited KelpDAO’s rsETH—a recent attack target—as one example. The findings suggest many cross-chain projects have a low tolerance for security redundancy.

BlockBeats report: On April 21, following the KelpDAO attack, Dune published an analysis on X revealing the security configurations of DVNs for all active OApps on LayerZero over the past 90 days. The data shows that among approximately 2,665 unique contracts, about 47% use the lowest security level of 1-of-1 DVN configuration, 45% use 2-of-2, and approximately 5% use 3-of-3 or higher configurations.


Analysis indicates that KelpDAO's rsETH falls into the 1-of-1 configuration category, highlighting the widespread lack of security redundancy in current cross-chain applications.
