What Auditors Should Check
If you're auditing a protocol with similar architecture to XSD Token, these are the critical security checks that could have prevented this incident (September 2023).
- Verify all logic paths related to Flash Loan Attack are guarded by proper access controls and input validation - see the Flash Loans Attacks attack class for patterns
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
