Katana | Security Overview — Audits, Proofs & Controls
Katana security overview covering OP Stack components, SP1 proof infrastructure, Agglayer, audits, internal assessments and governance safeguards.
Security scope
Katana security spans the execution stack, proof system, bridge, token contracts, DeFi integrations and governance. A strong assessment looks at the entire dependency graph rather than one contract in isolation.
Execution and proof stack
Katana uses an OP Stack-style Geth execution environment augmented with zero-knowledge proof infrastructure. Security therefore includes both traditional EVM execution risk and proving-system risk.
Agglayer and interoperability
Cross-chain infrastructure expands the security perimeter. Bridge contracts, messaging rules and remote chain assumptions can become critical dependencies for assets entering or leaving Katana.
Audits and internal review
Katana documents external security reviews of core components along with internal security assessment processes. Audits are evidence of review, not guarantees against all future vulnerabilities.
Governance safeguards
Admin multisig controls, timelocks and a Security Council add operational layers for upgrades and emergency response. Integrators should understand which contracts are upgradeable and who can pause or modify behavior.
Application security
Apps built on Katana still need their own secure coding, oracle design, approval UX, input validation and monitoring. Base-layer security does not automatically make every deployed protocol safe.
Frequently Asked Questions
Does Katana use security audits?
Katana documents external audits and internal security assessment processes for core components.
Do audits eliminate all risk?
No. Audits reduce risk but cannot guarantee the absence of vulnerabilities.
What can the Security Council do?
It provides independent oversight and emergency-response capabilities within Katana governance.
Do dApps need their own security review?
Yes. Application contracts and integrations introduce separate risks.
