From Mar. 6, 2024 to Mar. 8, 2024, Cata Labs engaged Veridise to review the security of an extension to their Generalised Incentives protocol. The review covered a smart contract implementing standardized incentives structure for relaying messages through an Arbitrary Message Bridge (AMB). Compared to the previous version, which Veridise has audited in the past, the new version allows for attaching deadlines to messages being sent (after which the message will not be executed) and allows relayers to be paid for notifying an application of a message timeout. Veridise conducted the assessment over 6 person-days, with 2 engineers reviewing code over 3 days. The auditing strategy involved a tool-assisted analysis of the source code performed by Veridise engineers as well as extensive manual code review.
