Constructor calls _disableInitializers()
Circle USYC's assessment for RD-F-023 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
ETH YieldCoin implementation constructor explicitly calls _disableInitializers() per verified Etherscan source: 'constructor(address _authority) { if (_authority == address(0)) revert BadAddress(); _disableInitializers(); }'. BSC USYCSatellite constructor ambiguous from WebFetch — response said 'does not explicitly call _disableInitializers()' but may rely on OZ Initializable state variable pattern instead. Given 96% of TVL is on BSC, the ambiguity on the BSC satellite is materially relevant. Yellow pending direct BSC source inspection.

Methodology #
Determine whether implementation contract constructors call `_disableInitializers()` to prevent re-initialization of the implementation directly.
