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

Kamino Lend'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 #

Kamino Lend is a Solana native Rust/Anchor program, not an EVM ERC-4626 vault. OpenZeppelin virtual-share offset pattern does not apply to Solana architecture.

Detail #

ERC-4626 is an EVM token standard (Ethereum Improvement Proposal). Kamino Lend is a Solana-native program using the Anchor framework (Rust), with no EVM deployment. The OpenZeppelin virtual-share offset (OZ >= 4.9) is an EVM/Solidity construct. The analogous Solana risk (precision loss in cToken exchange rate) was identified by Certora and patched before exploitation. Not applicable by architecture.

Methodology #

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