Signer rotation recency
Concrete's assessment for RD-F-031 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Safe has nonce=26 with 26 executions since Oct 2025 (~7 months). No explicit signer rotation (addOwner/removeOwner/changeThreshold) events observed in accessible tx history. Signer set appears stable. However, signer set was only established ~7 months ago (Oct 2025) with no prior rotation history available.
