Ether.fi announced on the X platform that the team has completed protocol-level security enhancements for the weETH cross-chain bridge across most deployment chains. According to PANews, no vulnerabilities have occurred, and potential risks have been proactively mitigated, with all security-related bridge parameters now fully controlled by ether.fi. Specific changes include locking the LayerZero send/receive message library, locking the DVN set and raising the threshold to 4/4, and tightening the pair rate limit on ether.fi's bridge contracts. Following these changes, LayerZero's multi-signature cannot modify the weETH bridge configuration on-chain, and each inbound message requires verification by all four DVNs. Ether.fi's next step is to evaluate the introduction of a second independent cross-chain stack outside of LayerZero and conduct a systematic risk assessment of the chains where weETH is located.
