Fusaka Upgrade To Undergo Rigorous Testing In New Ethereum Foundation-Backed Audit Contest
In Brief
The Ethereum Foundation has launched a four-week Fusaka audit to identify bugs before its planned late 2025 mainnet upgrade focused on security and throughput.
Ethereum Foundation, a non-profit supporting the Ethereum ecosystem, has announced the launch of the Fusaka audit contest, co-sponsored by Gnosis and Lido, and hosted on the Sherlock platform. The contest will run for four weeks, starting from September 15th, with the goal of maximizing scrutiny of the Fusaka upgrade to identify vulnerabilities before they can impact the network.
An audit contest is a time-limited competition where security researchers are incentivized to search for vulnerabilities within the Fusaka codebase. Only findings that comply with the defined rules and have an impact will be rewarded. Once the contest concludes, all findings will be reviewed, validated, and compiled into an official report to track and mitigate the vulnerabilities. Lessons learned will be shared, and top researchers will be recognized for their contributions.
In order to increase the incentive, valid findings reported during the first week of the contest will receive a 2x multiplier, while findings reported in the second week will receive a 1.5x multiplier on the points rewarded.
Gnosis has contributed $100,000, while Lido has contributed $25,000 to the contest. Beyond the funding, the co-sponsorship is strategically important for the ecosystem, as Ethereum upgrades impact the broader community. Spreading support across multiple organizations highlights that protocol security is a shared responsibility, not solely that of one entity.
Sherlock, a smart contract security platform where the contest will take place, works across the entire lifecycle of protocols by conducting collaborative audits with leading researchers, hosting large-scale contests to ensure maximum coverage, providing post-launch bug bounty programs, and offering financial coverage to enhance accountability. The platform is dedicated to maintaining the security of the Ethereum network, having previously conducted an audit of the Pectra Bytecode upgrade at the end of 2024.
Identifying Vulnerabilities In Fusaka Upgrade Ahead Of Upcoming Rollout
The contest aims to intensify scrutiny of the Fusaka code and identify potential vulnerabilities at an early stage. After the contest, a post-mortem of valid findings will be compiled into an official report. In addition to the contest, the Ethereum Foundation’s ongoing Bug Bounty program continues to offer up to $250,000 for identifying broader protocol issues.
The Fusaka upgrade encompasses a collection of approximately twelve Ethereum Improvement Proposals (EIPs) that focus on enhancing security, throughput, and efficiency. A key feature is Peer Data Availability Sampling, which helps distribute blob data checks across nodes, thereby increasing capacity for rollups. Although the upgrade is currently planned for late 2025, Tomasz Stańczak, co-executive director of the Foundation, has noted that the timeline may be delayed if there is insufficient coordination.
