ERC-4626 virtual-share offset (OZ ≥4.9)
Aave v3's assessment for RD-F-074 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Aave v3 Pool is not an ERC-4626 vault. The aToken/debtToken accounting uses the proprietary liquidityIndex / variableBorrowIndex model with virtual accounting (v3.1+). GHO Safety Module (stkGHO) uses a staking model, not ERC-4626. Umbrella (v3.6, June 2025) uses a different backstop model. No ERC-4626 satellite vault identified in the Aave v3 core protocol scope. Factor is not applicable.

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