First-depositor / share-inflation guard

dYdX v4 (dYdX Chain)'s assessment for RD-F-075 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Same rationale as RD-F-074. dYdX v4 MegaVault is Cosmos-native; there is no ERC-4626 first-depositor share-inflation vulnerability surface. The dYdX appchain has no EVM runtime and no ERC-4626 vault pattern anywhere in the v4 protocol. Per PD-024 (Cosmos-native-not-ERC-4626 rationale). No gap_reason required.

Methodology #

Determine whether the vault has a first-depositor guard (seed deposit on deploy, virtual-share offset, or floor-check).
