What Auditors Should Check
If you're auditing a protocol with similar architecture to Sportsbet.io, these are the critical security checks that could have prevented this incident (June 2024).
- Verify all logic paths related to Access Control are guarded by proper access controls and input validation - see the Access Control 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
