This repository documents the security audit history of the same evolving codebase:
- SAI (Single Collateral DAI): Initial implementation with comprehensive audits
- Dappsys: Core infrastructure development and security validation
- MCD (Multi Collateral DAI): Evolution to multi-collateral system
- RAI: Non-pegged stable asset built on the evolved codebase
- Core Contracts: Security validation of the refined implementation
- HAI Protocol: DeFi-native stablecoin on Optimism
- Enhanced Features: New core features with security validation
- AZUSD: Latest evolution of the codebase
- HAI-onOP Fork: Azos forked the HAI contracts as the foundation
Azos employs a comprehensive audit approach that leverages the full audit history:
- Direct Code Audit: Professional security firms audit our current implementation
- Evolutionary Validation: Running historical audit reports against our forked codebase
- Security Preservation: Ensuring our modifications maintain the security of the original
- Comprehensive Coverage: Full audit validation across the entire codebase evolution
- ✅ Completed: Azos Halborn Security Audit (Direct - 2025)
- ✅ Completed: MakerDAO Era Audits (2016-2018)
- ✅ Completed: Reflexer Era Audits (2020-2021)
- ✅ Completed: HAI Era Audits (2023-2024)
- 🔄 Ongoing: Continuous validation of the evolved codebase
When reviewing Azos audits, consider:
- Evolutionary Context: How the codebase has evolved from 2016 to 2025
- Security Preservation: How each iteration maintained security standards
- Vulnerability Prevention: How issues were addressed across iterations
- Code Integrity: How the core security patterns have been preserved
- Comprehensive Coverage: Full validation of the entire codebase evolution
Each audit serves as a validation of the evolving codebase:
- Historical Audit Reports: Running audits from each era against our current implementation
- Security Preservation: Verifying our modifications maintain the security of each iteration
- Vulnerability Prevention: Ensuring we haven't introduced new issues
- Code Quality: Maintaining the same security standards throughout evolution
- Comprehensive Validation: Full audit coverage of the entire codebase history
To add new Azos protocol audits:
- Add direct audit reports to the
./Azos/directory - Add evolutionary audit reports to their respective protocol directories
- Update this README with the new audit information
- Submit a pull request
This repository contains official Azos protocol audit reports and the complete audit history of the evolving codebase. All audit reports remain the property of their respective authors and auditing firms.
