Security Audit Report for AlphaX-Protocol's AlphaX-Protocol-Contract-Tron

The target of this audit is the code repository of AlphaX-Protocol-Contract-Tron of AlphaX-Protocol. This project is a TRON-based custody vault and gasless transfer system. The contract DEXVaultV1 is an upgradeable custody vault that allows users to deposit assets and permits withdrawals when predefined risk controls are satisfied. The gasless wallet layer consists of the contract GasFreeController, the contract GasFreeAccount, and the contract GasFreeFactory. Users can store funds in their own GasFreeAccount contracts, sign transactions off-chain, and rely on a relayer to pay for transaction costs during execution. The contract GasFreeController handles EIP-712-based permit execution, while the contract GasFreeFactory deploys deterministic accounts through CREATE2. Note that for contract DEXVaultV1, we only audit its compatibility with Tron.

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 find any critical issues within the audited codebase. However, we have identified some non-critical issues that should be addressed. Additionally, we have put forth recommendations and notes that should be taken into consideration. It is important to note that the scope of our audit was strictly limited to the specific code versions mentioned in the report. Any updates made subsequent to our review would require a re-evaluation.
