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

Meteora'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 #

ERC-4626 vault virtual-share offset (OpenZeppelin >= 4.9 pattern) is an EVM/Solidity-specific primitive for preventing first-depositor share inflation. Meteora is a Solana-native protocol written in Rust, deployed as BPF programs — ERC-4626 does not exist in this architecture. Taxonomy PD-024 (lending-only) and substrate mismatch (Solana vs EVM) both render this not_applicable.

Methodology #

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