★ Public initialize() without initializer modifier
Circle USYC'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 #
Ethereum YieldCoin implementation initialize() uses onlyInitializing modifier from OZ Initializable; prevents re-initialization. BSC USYCSatellite initialize() uses the same onlyInitializing modifier pattern per verified source. Teller implementation uses OZ Initializable checks. No unprotected initialize() found on any verified implementation.
