Ethereum Launches Fusaka Audit Contest with $2 Million Prize Pool

The Ethereum network has unveiled the Fusaka audit contest, a significant initiative aimed at bolstering the security of its upcoming upgrade. Co-sponsored by blockchain entities Gnosis and Lido, the contest is hosted on the Sherlock platform and will run for four weeks, commencing on September 15, 2025, according to Ethereum’s official blog.

Contest Details and Incentives

The Fusaka audit contest is designed to rigorously examine the Fusaka upgrade by incentivizing security researchers to identify and report vulnerabilities. To encourage early participation, findings reported in the first week will receive a 2x multiplier on their points, while those in the second week will have a 1.5x multiplier. This strategy aims to maximize participation and scrutiny from the get-go.

Gnosis and Lido have contributed financially to this initiative, with Gnosis providing $100,000 and Lido contributing $25,000. The collaboration underscores the importance of shared responsibility in securing Ethereum’s protocol, highlighting that network security is a collective effort rather than the burden of a single entity.

Understanding Audit Contests

An audit contest is a structured competition that challenges participants to find vulnerabilities within a specified timeframe. Researchers must adhere to predefined rules and only impactful findings are rewarded. Post-contest, all submissions are thoroughly reviewed and compiled into an official report to ensure vulnerabilities are addressed, and insights are disseminated.

Ongoing Security Measures

Beyond the Fusaka audit, Ethereum’s ongoing Bug Bounty Program continues to offer rewards of up to $250,000 for vulnerabilities that could affect the broader Ethereum network. This program complements the audit contest by providing continuous security incentives.

About Sherlock

Sherlock, the platform hosting the audit contest, is renowned for its comprehensive approach to smart contract security. Since its inception in 2021, Sherlock has conducted numerous audits, including the Pectra Bytecode upgrade in late 2024. The platform offers a full suite of security services, from collaborative audits to large-scale contests and post-launch bug bounty programs, ensuring robust protection for blockchain projects.

By launching the Fusaka audit contest, Ethereum seeks to reinforce its commitment to security, leveraging community collaboration to safeguard its network against vulnerabilities before the upgrade is fully implemented.
