About

The EthClient Summit is a technical forum where Ethereum client developers and their users meet face-to-face. It's a space for engineering excellence, sharing roadmaps, and surfacing real-world challenges.

This event is designed for teams actively building or operating on Ethereum clients.

FOR CLIENT TEAMS

Share your roadmap and highlight tradeoffs. Get direct feedback from people running your software in production. Align on upcoming features together.

FOR INFRASTRUCTURE TEAMS

Engage directly with client developers. Surface operational challenges like RPC performance, tracing quirks, indexing, and reorg handling. Help shape solutions upstream.

FOR ECOSYSTEM BUILDERS

Rollup, staking, and explorer teams who run or fork clients daily. Share how client decisions ripple into your stack. Collaborate on making the foundation more robust.

// Together we'll align on features, solve problems, and strengthen Ethereum's foundations.
