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

Babylon Protocol'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 #

Babylon uses Bitcoin Taproot UTXO accounting (Bitcoin mainnet) and Cosmos SDK module accounting (Genesis chain). No ERC-4626 vaults exist anywhere in the core protocol. Virtual-share offset is an EVM/Solidity/OpenZeppelin pattern inapplicable to this architecture. data cache: non_evm_substrate: true. Taxonomy PD-024: ERC-4626 offset is lending-only.
