Wu Shuo learned that EtherFi has completed comprehensive security reinforcement for the weETH cross-chain bridge on most deployed chains, with no attack incidents reported; this adjustment includes fixing the LayerZero message sending and receiving library, fixing the DVN set and raising the verification threshold to 4/4, and tightening the path-level rate limit parameters of its proprietary bridge contract. After the adjustment, the LayerZero multi-signature no longer has on-chain permission to modify the weETH bridge configuration, and all cross-chain messages must be verified by all 4 DVNs and constrained by the path-based rate limiting mechanism to limit potential risk spread.
