Bridge validator-set rotation recency
Axelar Network's assessment for RD-F-155 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Axelar validator set requires periodic key rotation per protocol design. The 2024 vulnerability disclosure (chain-halt via auto-deregistration) was patched via governance proposal 256. No confirmed validator-set freeze or stale key issue identified. However, the exact date of the most recent OperatorshipTransferred event on AxelarAuthWeighted was not extracted in this session — requires axelarscan.io event log or Etherscan event filter. Yellow pending curator confirmation of last rotation date.
