★ Reinitializable implementation (no _disableInitializers)
BlackRock USD Institutional Digital Liquidity Fund (BUIDL)'s assessment for RD-F-143 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
DSToken v4 uses an initialized() guard (visible in ABI), suggesting an initialization lock. Whether constructor calls OZ's _disableInitializers() is not confirmed from ABI alone. Custom proxy's setTarget() mechanism reduces direct re-init risk vs. standard UUPS. Conservative score: yellow. If _disableInitializers() absent in constructor → red.

Methodology #
Determine whether the implementation contract does not call `_disableInitializers()` in its constructor, leaving re-initialization possible.
