ether.fi: WeETH cross-chain bridge security has been strengthened, LayerZero multi-signature permissions have been restricted, and the DVN threshold has been increased.
CoinFeed reported on April 24th that ether.fi announced on its X platform that its team has completed protocol-level security hardening of the weETH cross-chain bridge on most deployed chains, with no vulnerabilities found. This proactively closes potential risks and puts all security-related bridging parameters under complete control of ether.fi. Specific changes include: locking the LayerZero send/receive message library, locking the DVN set and increasing the threshold to 4/4, and tightening the pairwise rate limit on ether.fi-owned bridging contracts. After the changes, LayerZero's multisignature cannot modify the weETH bridge configuration on-chain, and each inbound message must be verified by all four DVNs. Next, ether.fi will evaluate introducing a second independent cross-chain stack in addition to LayerZero and conduct a systemic risk assessment of the chains hosting weETH.
