Constructor calls _disableInitializers()

Yearn Finance's assessment for RD-F-023 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

OZ _disableInitializers() is a Solidity UUPS/Transparent proxy construct. Yearn V3 is Vyper with a sentinel-value initialization lock (self.asset = self in __init__). V2 vaults are not proxied implementations. The OZ-specific Solidity mechanism is architecturally inapplicable to Vyper-based vaults.

Methodology #

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