ERC-4626 virtual-share offset (OZ ≥4.9)
JustLend DAO'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 #
JustLend jTokens are TRC-20 receipts using the Compound v2 cToken exchange-rate accounting model on TRON (TVM). ERC-4626 is an Ethereum standard; jTokens on TRON are not ERC-4626 vaults and the OZ ≥ 4.9 virtual-share offset mechanism is architecture-specific to ERC-4626 and not applicable here. The Compound v2 cToken exchange-rate model has its own first-depositor vulnerability path (assessed under RD-F-070 and RD-F-075).

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