Aave V4 Completes 345-Day Security Audit with No Critical Vulnerabilities Found

Aave Labs recently announced that the Aave V4 protocol has completed a comprehensive security review lasting approximately 345 days, with a total investment of $1.5 million. The project adopted a "security-first" strategy, implementing multi-layered security controls from the initial architecture design phase. The security review included manual audits, formal verification, invariant testing, fuzz testing, and a six-week public security competition that attracted over 900 participants who submitted more than 950 reports. Audit results showed that all major audit firms—including ChainSecurity, Trail of Bits, and Blackthorn—found no high-severity vulnerabilities. Aave V4 introduces a new hub-and-spoke modular design, resulting in a smaller codebase compared to V3 and enhancing audit efficiency. Aave Labs stated it will continue maintaining its formal verification framework and invariant testing suite, and plans to establish an ongoing bug bounty program to ensure the protocol’s long-term security.
