v4-security-foundations

Secure Uniswap v4 hooks require a security-first framework focusing on threat modeling, delta accounting, and access control to prevent fund loss. Review the threat model and enable only necessary protections before implementing callbacks.

V4 hook vulnerabilities that drain user funds typically stem from incorrect authorizations and improper delta handling. Applying defense-in-depth patterns and risk-oriented guidance mitigates these security threats during development and auditing.

Implement access control for a Uniswap v4 hook by applying patterns for PoolManager verification and router allowlisting. These security-first practices ensure only authorized callers execute sensitive hook callbacks.

Audit Uniswap v4 hooks for delta accounting issues by using template and checklist resources designed for risk-aware hook design. This framework guides testing to identify incorrect delta handling that could lead to fund loss.

Safe upgrade practices for v4 hook smart contracts involve applying defense-in-depth patterns and risk-oriented guidance. Reference security-first foundations to maintain authorization integrity and prevent vulnerabilities during contract upgrades.
