TechFlow reports that on March 5, Aave Labs announced the completion of a comprehensive security review for the Aave V4 protocol, spanning approximately 345 days and costing a total of $1.5 million. The project adopted a “security-first” strategy, implementing multi-layered security controls from the architectural design phase onward. The security review included manual audits, formal verification, invariant testing, fuzz testing, and a six-week public security competition, which attracted over 900 participants submitting more than 950 reports.
Audit results showed that no high-severity vulnerabilities were identified by any of the major auditing firms—including ChainSecurity, Trail of Bits, and Blackthorn. Aave V4 features a new hub-and-spoke modular architecture, resulting in a smaller codebase compared to V3 and thereby improving audit efficiency. Aave Labs stated it will continue maintaining its formal verification framework and invariant test suite, and plans to launch an ongoing bug bounty program to ensure the protocol’s long-term security.
