Role separation: upgrade ≠ fee ≠ oracle
Hyperlane's assessment for RD-F-035 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Mailbox.sol uses a single onlyOwner pattern for all admin operations. Upgrade role (ProxyAdmin v1 → 3-of-6 Safe) and operational config (Mailbox owner) are distinct contracts/address paths. No separate fee-collection role. Oracle config (setDefaultIsm) is an owner function. Partial role separation exists between upgrader and config owner, but config functions are not role-separated among themselves.
