According to Wu, EtherFi announced that it has completed a comprehensive security upgrade for the weETH cross-chain bridge on most deployed chains, with no attack incidents reported. The adjustments include fixing the LayerZero messaging library, securing the DVN quorum by raising the verification threshold to 4/4, and tightening the path-level rate limit parameters of its proprietary bridge contracts. After the update, the LayerZero multisig no longer has on-chain permissions to modify the weETH bridge configuration. All cross-chain messages must be verified by all 4 DVNs and are constrained by a path-specific rate-limiting mechanism to mitigate potential risk spread. https://(wublock123.com)/news/etherfi-weeth-cross-chain-security-upgrade-dvn-4-4-restrict-layerzero-multisig-60031
