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

Aerodrome 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 #

Aerodrome does not use ERC-4626 vault architecture. Aerodrome Pools LP positions are ERC-20 tokens (constant-product Solidly-style AMM); Slipstream positions are NFT-based (Uniswap v3-style). Neither is an ERC-4626 vault. The share-inflation attack this factor targets is not applicable. OZ version is 4.8.0 (per data cache) but ERC-4626 is not used.

Curator note
Aerodrome data cache â€” OZ versionData cache oz_contracts_version: '4.8.0'; ERC-4626 not used in either AMM product â€” OZ version is below 4.9 but irrelevant as ERC-4626 is not the LP share model.retrieved 2026-05-04

Methodology #

Determine whether ERC-4626 vaults use OpenZeppelin ≥4.9 virtual-share offset pattern to prevent first-depositor share-inflation.
