- [Audits](https://city-protocol.gitbook.io/docs/security/security-and-risk/audits.md): Independent audit reports for City Protocol's components and products, and the proof-of-solvency dashboards.
- [Oracle and NAV design](https://city-protocol.gitbook.io/docs/security/security-and-risk/oracle-and-nav-design.md): How a NAV report becomes eligible for settlement, and what happens when an update fails.
- [Risk isolation and emergency controls](https://city-protocol.gitbook.io/docs/security/security-and-risk/risk-isolation-and-emergency-controls.md): How failures stay contained, where liquidation and unwinding can occur, and how the system pauses.
- [Contract security](https://city-protocol.gitbook.io/docs/security/security-and-risk/contract-security.md): The Curated Vault contract surface, role separation, settlement, limits and monitoring in technical detail.
- [Cross-chain architecture](https://city-protocol.gitbook.io/docs/security/cross-chain-architecture.md): The networks City Protocol runs on, how $CIT is bridged, and the risks of operating across chains.
