Aave Labs has announced the successful completion of a 345-day security audit for the Aave V4 protocol, with no critical vulnerabilities detected. The audit, which cost $1.5 million, involved a comprehensive security-first approach, including manual audits, formal verification, invariant testing, fuzz testing, and a public security competition. Over 900 participants submitted more than 950 reports during the six-week competition. Major audit firms such as ChainSecurity, Trail of Bits, and Blackthorn confirmed the absence of high-severity vulnerabilities. Aave V4's new hub-and-spoke modular design has resulted in a smaller codebase, improving audit efficiency. Aave Labs plans to maintain its formal verification framework and invariant testing suite, alongside establishing a continuous bug bounty program to ensure ongoing security.
