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

SUNSwap (sun.io)'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 #

SUNSwap V1–V4 are Uniswap-family AMM pool contracts on TVM (TRON Virtual Machine), not ERC-4626 vaults. V1 uses constant-product LP tokens; V2/V3 use NFT-represented positions (NonfungiblePositionManager); V4 uses singleton pool manager. No ERC-4626 vault wrapper exists or has been confirmed. TVM does not implement ERC-4626 as an on-chain standard. PD-024 lending-only N/A.

Methodology #

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