Security Audit Report for MegaETH's Staking Contracts

The target of this audit is the code repository of Staking Contracts of MegaETH. The Staking Contracts of MegaETH is a KPI-based staking system for the MEGA token on the MegaETH chain. Users can stake MEGA tokens and earn MEGA tokens based on achieved KPI milestones (i.e., tranches). Each tranche is created with a reward token and maturity curves that scale rewards according to the staking duration. This update introduces three key features: (1) a pending reward mechanism, (2) integration with Predicate2 attestations, and (3) a linear maturity curve.

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.
