★ Public initialize() without initializer modifier
Hyperlane's assessment for RD-F-022 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
All examined implementation contracts use the OZ initializer modifier on initialize(): Mailbox (`external initializer`), HypERC20Collateral (`public initializer`), HypNative (`public initializer`), HypERC20 (`initializer`), HypERC4626Collateral (initializer present). No unprotected initialize() found. Score: green.

Methodology #
