Proposal Review
OpenZeppelin, the Security Member of the ARDC, reviewed the AIP: ArbOS 31 “Bianca” proposal and its execution instructions. If enacted, the proposal execution will activate Stylus, Alternate Signature Verification, and Automatic Treasury Deposits using seven on-chain governance action contracts (GACs) that alter the ecosystem in the ways described in the proposal description.
The new, on-chain contracts match their audited versions with the exception of the contracts in the OffchainLabs/fund-distribution-contracts for fund distribution which were not fully covered by the audit scope and with some files receiving some optimization changes since the final audit commit. We recommend getting a confirmation on whether the latest version of these files were covered in the audit.
