The Ethereum Foundation kicked off a four-week audit contest for its upcoming Fusaka upgrade, offering up to $2M in rewards to white hats who find bugs before the hard fork hits mainnet—potentially as early as Q4 2025.
What’s the Scoop?
- Audit Window Opens: Running from Sept. 15 to Oct. 13, the contest is hosted by Sherlock and co-sponsored by Gnosis and Lido. Week one offers 2x rewards, followed by 1.5x in week two to encourage early participation.
- Fusaka Upgrade Scope: The upgrade bundles a dozen EIPs focused on security, throughput, and efficiency, including Peer Data Availability Sampling—a feature designed to improve rollup capacity by decentralizing blob data checks.
- Building on Past Audits: Sherlock previously led Ethereum’s Pectra bytecode review, part of the Foundation’s strategy to combine crowdsourced contests with standing bounties for better pre-launch security.
Bankless Take:
The auditing process is an essential aspect of any major coding initiative. Although the consequences of a bug in Ethereum could be much greater than the committed $2M bounty reward, this audit contest should help to flush out any remaining upgrade flaws.
