Security Audit Report for Rhea Finance's xRHEA Token

The target of this audit is the private code repository of xRHEA Token of Rhea Finance. This incremental audit reviews the xRHEA staking contract upgrade, which introduces time locked unstake requests, configurable exit fees, fee distribution and retry mechanisms, and quota controlled instant unstaking for approved accounts. The audit further covers high precision virtual pricing, state migration, asynchronous NEP-141 callback handling, reward accounting, storage management, and the integration of the upgraded unstake workflow with the existing withdrawal implementation.

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.
