OpenZeppelin, as Security Member of the ARDC, was asked to review a live Arbitrum DAO proposal (id: 108365…9297) which would modify the Arbitrum Security Council from a seven-of-twelve to a nine-of-twelve signing threshold for non-emergency actions.
Overall, we found the proposal to be well-formed, to follow established methodologies set forth by the Arbitrum Constitution, and to pose no other risks to the protocol even if only part of the call chain succeeds. You can review our full analysis in the report linked below.
