ERC-4626 virtual-share offset (OZ ≥4.9)

Convex Finance's assessment for RD-F-074 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

The Booster contract (0xF403C135812408BFbE8713b5A23a04b3D48AAE31, Solidity 0.6.12) is not an ERC-4626 vault and does not use share-based accounting in an ERC-4626 pattern. No virtual-share offset mitigation is relevant. Per PD-024, F074 is applicable only to ERC-4626 vault protocols.
