Dedaub was commissioned by the Ethereum Foundation to perform an audit/study of the impact of Ethereum Improvement Proposal (EIP) 3074 (AUTH and AUTHCALL) on existing contracts.
order to appraise the impact of the proposed change, we performed
extensive queries over the source code and bytecode of deployed
contracts, inspected code manually, examined past
transactions/balances/approvals, and informally interviewed developers.
