Audit Philosophy
The SDK is designed with the assumption that it may be reviewed by external auditors, grant committees, or ecosystem partners. Transparency and explicit boundaries are preferred over implicit trust.
Codebase Structure
- Clear separation between core logic and provider integrations
- Minimal side effects and explicit data flow
- Configuration-driven behavior where possible
- No hidden network calls or undocumented dependencies
Data Handling Guarantees
- No raw identity documents are stored by the SDK
- No personally identifiable information is written on-chain
- Verification states are abstracted and minimized
- Logging avoids sensitive or correlatable data
Configuration & Secrets
Provider credentials and sensitive configuration values are expected to be supplied via environment variables or secure secret managers.
- No secrets are committed to the repository
- Example configuration files exclude real credentials
- Rotation and revocation are supported without redeploying code
Third-Party Dependencies
- Dependencies are intentionally minimized
- Provider SDKs are isolated behind abstraction layers
- Dependency upgrades are reviewed for breaking or risky changes
Recommended Audit Focus Areas
- Verification state transitions and enforcement logic
- Boundary between off-chain verification and on-chain usage
- Provider response validation and normalization
- Failure modes and fallback behavior
Known Limitations
This SDK does not claim to guarantee regulatory compliance in all jurisdictions. Final responsibility for compliance rests with the integrating application.
Continuous Improvement
Security and compliance requirements evolve. The SDK treats audit readiness as an ongoing process and welcomes responsible disclosures and improvement proposals.
