Hunt the Bug, Save the Chain: Uncovering Bugs in EIP Implementations | Devcon SEA

Thu, Oct 2, 2025, 12:00 AM

In this workshop you can find a bug in an EIP implementation on a test network! The Ethereum Foundation Testing Team oversees cross-client execution specification testing, which is critical to avoid consensus issues at the smart-contract execution level. You'll implement tests for a new EIP from scratch using the ethereum/execution-spec-tests framework and execute them on a local test network with a faulty client. Anyone attending has the chance to find the issue and break the network!
