v4-security-foundations

To prevent vulnerabilities in Uniswap v4 hooks, use a security-first foundation that enforces pool manager verification and safe delta accounting. This approach defines threat models and provides templates for robust, auditable hook development.

Best practices for delta accounting in v4 hooks involve using risk-aware design patterns that properly track token balances and enforce pool manager verification. Audit-ready templates ensure these accounting mechanisms remain robust against manipulation.

Set up safe v4 hook permissions by starting with a base template that has all callbacks disabled by default. Enable only the specific hook permissions you need in getHookPermissions to minimize the attack surface before deployment.

Yes, v4 hook development requires explicit threat modeling to identify risks and establish access-control scaffolding. Building hooks with proven security foundations reduces vulnerability risk for teams shipping auditable checklists.

The safest way to implement upgrade patterns for v4 hooks is to use predefined, safe upgrade templates provided by a security foundation. This ensures upgrades maintain delta accounting integrity and do not introduce access control vulnerabilities.

No, you should not skip access-control scaffolding for v4. A base hook template provides a safe starting point with permissions disabled, but you must actively implement risk-aware access controls and threat models for your specific use case.
