Security Audit Report for bitgetwallet's bgw-swap-aggregator-solana

The target of this audit is the private code repository of bgw-swap-aggregator-solana of bitgetwallet. This update introduces partner-integrated swap entrypoints for the Solana swap aggregator, enabling protocol fees to be split between the platform and a designated integration partner. It adds partner fee parameters, partner-specific fee collection for both SPL tokens and native SOL, and new swap wrappers across v1, v2, and v3 routes. The update also reorganizes swap modules into versioned directories, exposes the new instructions in the program interface, adds fee split logging, and includes a custom heap allocator for Solana builds.

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.
