Security Audit Report for Rhea Finance's Agg-Oracle

The target of this audit is the private code repository of Agg-Oracle of Rhea Finance. The reviewed update extends the protocol’s oracle infrastructure by integrating Atlas and Outlayer as dedicated price-data sources. The changes introduce source-specific payload decoding and validation, signature verification, authorized-signer configuration, price normalization, price-reporting interfaces, and token-to-feed mappings. The contract’s storage layout and migration procedures have also been updated to accommodate the new signerrelated state while maintaining compatibility with previously stored oracle data.

Please refer to the report for the detailed audit scope.

Our audit methodology employs automated vulnerability scans, manual verification, and business logic analysis to uncover potential security issues coupled with gas and code quality optimization recommendations.

In summary, we did not identify any potential issues within the audited codebase. However, we have some recommendations and notes that should be considered to further enhance the protocol's quality, security, and reliability. With no potential issues identified, the project demonstrates a relatively high level of security. It should also be noted that the scope of our audit was strictly limited to the specific code versions detailed in the report. Any updates subsequent to our review would necessitate a re-evaluation.
